Published: January 2024

Background and Aims: Sperm DNA fragmentation (SDF) is caused by apoptosis, oxidative stress or incomplete chromatin maturation and can result in male infertility and poor reproductive outcomes. Despite growing trends, there are no specific recommendations on specific diagnostic tests used, assay cut-offs or abstinence periods prior to SDF testing. Therefore, we conducted a global survey to evaluate the approaches used to diagnose SDF, towards a consensus in the field of SDF research and clinical management. Method: The survey collected cross-sectional global data from 55 countries following the CHERRIES protocol. 436 respondents included clinicians, researchers and reproductive biologists from academic, public and private health sectors, all of whom utilize SDF testing in their routine patient care and practice (Fig. 1). Results: Survey results showed that TUNEL (28.6%), SCSA (24.1%), SCD (19.1%) and Comet (5.3%) were most frequently used to diagnose SD (Fig. 2A). Assays were chosen primarily due to their availability (70.0%), cost (44.05%) and accuracy (35.48%). Published evidence on assays (25.71%), training of staff (25.48%), cost to patients (21.67%), assay time (18.81%), ease of interpretation (18.33%) and performance (17.38%) were taken lesser into consideration when selecting SDF diagnostic tests (Fig. 2B). Assay cut-offs of “30% or higher” (33.7%) were most frequently used to diagnose SDF (Fig. 2C). Finally, an abstinence period of 3-5 days was mostly recommended (53.6%; Fig. 2D). The results of this survey provide valuable data on SDF assays used in clinical practice as well as factors affecting assay choices such as availability of resources, personnel and complexity in assay processing. As decreased abstinence period is associated with lower SDF, testing is recommended with an abstinence period of less than five days. We observed that there was a lack of standard cut-off values, and every laboratory should establish its own reference values based on predictive values for fertility outcomes. Conclusion: We present new data associated with SDF testing in real-world practice, on a global scale. The trends and conclusions derived from the study are recommended for inclusion into the 6[Formula: see text] Edition WHO Manual, towards optimized patient care.

Published: January 2024

Background and Aims: Several studies have found that diet is critical during a female’s pregnancy. The nutritional condition of pregnant women can have long-term consequences for their children, particularly the growth of the reproductive system. However, previous studies have various opinions regarding whether or not the nutritional status of the maternal correlates with seminiferous tubule diameter and the Sertoli cell amount of their offspring. This study aims to observe the effect of low protein diet on pregnant mice towards the offspring’s seminiferous tubule diameter, Sertoli cell, and vacuole. Method: Ten female ddY mice were split into two groups and given two months of treatment with either a normal protein diet (14%) or a low protein diet (10%). The mice were mated to produce offspring after treatment. Each group had five male progenies that were raised until they were three months old before being terminated to retrieve their testicles. Hematoxylin-eosin staining was used for histological analysis of the testicle sample. Testicles samples were observed for seminiferous tubule, Sertoli cell, and vacuole. Data was presented as mean & standard deviation. ANOVA and the Mann-Whitney U test was used to analyze the data. Statistical significance was accepted at p<0.05. Results: There were no statistical differences between the offspring’s seminiferous tubule diameter and Sertoli cell count in the normal protein diet group and the low protein diet group (6.28±1.79 vs 6.47±0.79; 4.72±3.13 vs 4.84±2.81). On the contrary, the low protein diet group has a higher vacuole amount than the normal protein diet group (6.76±4.59 vs 3.64±3.07; P=0.004). Conclusion: A maternal low-protein diet did not affect the Sertoli cell population or the length of the child’s seminiferous tubules but led to a significant increase in vacuoles.

Published: January 2024

Background and Aims: Jakarta is a metropolitan city of Indonesia and most people in Jakarta are working on various occupation such as technology-based and highly skilled occupations are common (construction workers, engineers, programmer, entrepreneurs) and desk-based workers. Those occupation, stress from those occupation and environment may impair male fertility. This study was aimed to determine specific occupations, occupational stress and environment and their association with sperm parameter. Method: A descriptive cross-sectional study was used, and 24 male participants underwent IUI treatment in Yasmin Fertility Clinic, Jakarta were recruited. Sperm concentration, motility, morphology, velocity was analyzed using Computer Assisted Sperm Analysis (CASA) and sperm DNA fragmentation index was assessed using Sperm Chromatin Structure Assay (SCSA). Interview was also conducted to obtain information on age, length of marriage, biological children, occupational exposure, occupational-related psychological stress. The results were compared to parameter in WHO manual 6th edition. Results: All 24 participants experienced exposure to potential disruptor to fertility such as vehicle emission, smoke inhalation and computer radiation (Fig. 1). Their raw semen parameters were lower compared to WHO manual 6th edition. Further results indicated that washing increased the value of all standard parameters and reduced sperm DNA fragmentation index in all samples. Further results showed abnormal morphology and sperm on fresh ejaculate are affected by stress intensity and frequency. However, total motility and abnormal morphology are significant correlated to stress intensity and frequency on both before and after sperm washing (Table 1). Conclusion: Types of occupation and highly exposed to air pollution and/or demands prolonged time of sitting behaviour pose higher risk of sperm quality deterioration. Also, psychological stress resulted from workload may associate with sperm parameters outcome.

Published: January 2024

Background and Aims: The Sperm DNA Fragmentation (SDF) assay has been a promising tool for evaluation of male fertility in assisted reproductive technology (ART). Our primary aim is to assess the impact of SDF levels (<15% and ≥15%) on the laboratory and clinical outcomes; and secondary aim to evaluate those outcomes among 3 ART subgroups namely IVF–ICSI Split, IVF and ICSI cycles. Method: This retrospective cohort study was conducted on 1148 males who presented along with their partners for infertility management at the PIVET Medical Centre between 2013 and 2022 and had their SDF assay performed by Halosperm. They undertook 1600 ART cycles with outcomes divided into 2 groups based on SDF levels <15% and ≥15%. Categorical data were analyzed by Chi-squared or Fisher’s exact test. Results: The overall rates of fertilization, blastocyst development, good–quality blastocyst, clinical pregnancy, miscarriage and livebirth rates were comparable between the <15% and ≥15% SDF groups. Nevertheless, when comparing these outcomes according to female age groups, the clinical and livebirth rates were significantly higher in women <35 years in the SDF <15% (44.1%, p=0.04; 38.6%, p<0.01). Among the 3 ART modalities, the fertilization rates were optimised in both SDF groups by ICSI (75.5%, p<0.0001; 74.1%, p<0.0001), however ICSI also has the lowest blastocyst rate in both SDF groups (p<0.0001 and p<0.001). The IVF-ICSI Split modality generated the highest rate of good-quality blastocysts in both SDF groups <15% (44.9%, p<0.0001) and ≥15% (50.0%, p<0.001). Although the clinical pregnancies were not highest in the IVF modality, it carried the lowest miscarriage rate resulting in the highest live birth rate in SDF <15% group where the women were aged <40 years. Conclusion: The SDF assay is predictive of clinical and livebirth rates for women aged <35 years. IVF is an effective modality among women aged <40 years where the SDF level is <15%.

Published: January 2024

Background and Aims: About 1% of men suffer from azoospermia, a condition of having no sperm in the ejaculate. Non-obstructive azoospermia, which affects 60% of azoospermia patients, is the most severe form of male infertility and requires testicular sperm extraction for sperm retrieval. Despite a 50% success rate, if no mature sperm is found, NOA men have no choice become biological fathers. To overcome this, researchers have attempted to use spermatid injection techniques, such as round spermatid injection (ROSI) or elongating/elongated spermatid injection (ELSI), to give hope for pregnancy. Spermatids are immature sperm but contain a haploid genome as spermatozoa. The aim of this prospective cohort study was to evaluate the effectiveness of ROSI and ELSI in cases where spermatozoa were unavailable. Method: Ninety-nine men diagnosed with NOA were recruited for the study. When the male partners lack spermatozoa in the testicular biopsy but have normal good-looking spermatids, they are consulted to join in the research. The intervention group received ROSI and ELSI, while the control group received spermatozoa injection into oocytes (ICSI). The primary outcome measures were fertilization, embryo development, clinical pregnancy, and live birth rate. Results: The overall fertilization rate (2PN) per MII oocyte injected after ROSI was low at 31.0% compared to ELSI and ICSI at 67.7% and 77.2%, respectively. The pregnancy rate after ROSI was also low, with 3.3% per transferred cycle and 2.2% per embryo transferred. The pregnancy rate of ROSI was much lower than ELSI (42.9%) and ICSI (55.6%). Normal pregnancy and live birth resulted in three groups (Table 1). Conclusion: ROSI and ELSI can be considered alternative methods of infertility treatment in cases where spermatozoa are unavailable.
#241 : Impact of Antioxidants in Improving Semen Parameters Like Count, Motility and DNA Fragmentation in Sub-Fertile Males: A Randomized, Double Blind, Placebo Controlled Clinical Trial
Authors: Patki Ameet 
Published: January 2024

Background and Aims: Male infertilities are solely responsible for 20-30% of infertility cases. Oxidative damage of sperm DNA is positively linked with oligoasthenoteratozoospermia (OAT), and male infertility. The antioxidants are being explored worldwide to combat OAT, sperm DNA fragmentation and reactive oxygen species. The objective of the study was to assess the effectiveness of an antioxidant blend in improving sperm count, semen parameters and reducing DNA fragmentation index (DFI) in sub-fertile males. Method: A prospective, double-blind, randomized, placebo-controlled trial was conducted in 300 sub-fertile males (25–45 years) from ten study sites in India. Subjects were randomized in either the antioxidant blend treatment group or placebo group. We assessed changes in sperm count, motility, normal morphology, semen volume, and percent DFI before and after treatment (90 days). To further stratify data on different criteria post hoc analysis was performed. Statistical analysis was performed using SPSS 10.0 software. Results: There were improvements in sperm count, semen volume, sperm motility, and sperm normal morphology in the treatment group. There was improvement in sperm count in severe oligospermia subjects (sperm count < 5 million/mL, 5–10 million/mL, 10.1–15 million/mL), and high-extremely higher baseline DFI (20–30%, 31–40% and above 40%), as per post hoc analysis. There was no premature discontinuation and adverse events were reported during the study, indicating safety and well-tolerability of treatment. Conclusion: Study results confirmed the well-researched fact of antioxidants being effective to reduce oxidative stress and thus improve sperm DNA integrity and also improved semen parameters particularly in males aged 40 and above.
#337 : Six Characters of Seminiferous Tubules Appearances During Micro-Tese Related with Different Sperm Retrieval Rate
Authors: Zhang Jing , Chen Hong , Zhao LuGang , Liu GuiHua , Liang XiaoYan , Fang Cong 
Published: January 2024

Background and Aims: For non-obstructive azoospermia (NOA) patients, micro-TESE is considered to have higher sperm retrieval rate (SRR) than traditional surgery. However, various clinical parameters are not reliable predictors for the presence of focal spermatogenesis and SRR. This study summarized the characters of seminiferous tubules appearances and investigated their relationship with SRR. Method: This was a retrospective study. From September 2014 to April 2023, 638 NOA patients treated with micro-TESE were divided into six groups according to the seminiferous tubules appearances (Group-A: homogeneously thick, Group-B: homogeneously thin, Group-C: seminiferous tubules were severe thin and loss the tubal appearance, Group-D: the testicles were filled with hyperplastic Leydig cells, seminiferous tubules were severe thin and rare, Group-E, thick tubules mixed with thin tubules, Group-F, extensive testicular microlithiasis). Age, testicular volume, serum FSH, testosterone level, SRR and the heterogeneous seminiferous tubules presenting rate (HSTPR) were compared. Results: Sperms were successfully retrieved in 333 cases (SRR=52.2%). There were no statistical differences in age, testicular volume, FSH and testosterone level between the patients who succeeded and failed to obtain sperm (Table 1, all [Formula: see text]>0.05). The constituent ratio of etiology was different in the six groups (Table 2, [Formula: see text]<0.05). Between the six groups, testicular volume, FSH, testosterone, SRR and HSTPR were statistically different (Table 3, all [Formula: see text]<0.05). Conclusion: Age, testicular volume, FSH and testosterone were insufficient to predict the SRR of NOA patients. Micro-TESE is commended to terminated when sperm are retrieved in case that the seminiferous tubules are rare or too thin to present tubal appearance, thick tubules mix with thin tubules or extensive testicular microlithiasis present (Group C-F). If the tubules appear homogeneously thick or thin, micro-TESE would has less advantage comparing with conventional multiple TESE because of the difficulty to identify the differences between the tubules even if the sperm is finally retrieved (Group A-B).
#338 : Insights into the Zona-Pellucida Mediated Selection of Fertilization-Competent Spermatozoa
Authors: Leung Erica Tsz Ying , Lee Chuk-Lun , Chiu Philip C.N. 
Published: January 2024

Background and Aims: Human zona pellucida (ZP) selectively interacts with high-quality spermatozoa characterized by superior morphology and normal chromatin structure to achieve fertilization. Human ejaculate contains millions of spermatozoa with varying degrees of fertilization potential and genetic quality, of which only thousands of motile spermatozoa can bind to the ZP at the fertilization site. However, direct evidence for ZP-mediated sperm selection process is lacking. This study aims to demonstrate that spermatozoa-ZP interaction represents a crucial step in selecting fertilization-competent spermatozoa in humans. Method: Human spermatozoa and oocytes were obtained with written consents from the donors attending our assisted reproduction program. Acrosome intact, ZP-bound and unbound spermatozoa were recovered using the modified spermatozoa-ZP coincubation assays. ZP-binding protein expression on ZP-bound and unbound spermatozoa were examined by immunofluorescence staining. And the genetic integrity and epigenetic landscapes were evaluated by TUNEL assay, COMET assay, acridine orange staining, chromomycin A3, and immunofluorescence staining for 5-methylcytosine. Results: The time course data demonstrated that ZP interacted with a small proportion of motile spermatozoa. Heat shock 70 kDa protein 2 (HSPA2) and sperm acrosome associated 3 (SPACA 3) are two protein markers associated with the sperm ZP-binding ability. ZP-bound spermatozoa had a higher percentage of positive HSPA2 (85.8% vs. 45.9%, p<0.05) and SPACA3 signals (86.3% vs. 30.5%, p<0.05) than the unbound ones. The signal intensities of both markers were stronger in the ZP-bound spermatozoa than the unbound ones. ZP-bound spermatozoa had a significantly higher level of normal morphology, DNA integrity, chromatin integrity, protamination and global methylation when compared to the unbound ones. Conclusion: Our results validated the functional role of spermatozoa-ZP interaction in providing diagnostic information regarding the fertilization potential and genetic qualities of spermatozoa independent of those derived from the standard semen analysis.
#363 : Kisspeptins and Human Reproduction: New Challenges in the Management of Couple Infertility
Authors: Sellami Afifa , Daoud Salima , Abdelkafi Olfa , Amor Maroua Ben , Moalla Faradis , Rebai Tarak 
Published: January 2024

Background and Aims: Human reproduction is strictly controlled by a complex neurohormonal system including the gonadotropin-releasing hormone (GnRH) production, which stimulates anterior pituitary gonadotropes secretion and thereby gonadal function. Now, it is well known that GnRH neurons are regulated by Kisspeptins, a family of neuropeptides encoded by the Kiss1 gene and produced mainly in the arcuate and periventricular nuclei of the third ventricle in the hypothalamus. This review aims to provide an updated view in the physiological effects of kisspeptins in male and female reproduction and to highlight future research challenges in therapeutic alternatives for the management of couple infertility. Method: A non-systematic review of the literature was performed by screening PubMed up to April 2023 using the search terms including “Kisspeptin”, “gonadotropin-releasing hormone”, “male infertility”, “female infertility”, “sperm”, “oocyte”, and “Assisted Reproductive Technology”. Results: Many reports suggested the importance of kisspeptins in various aspects of male and female reproduction, from sexual differentiation and puberty onset to adult regulation of gonadotropin secretion and the metabolic control of fertility. Kisspeptin is involved in oocyte development, quality of semen, steroidogenesis in both the ovaries and testes, sexual desires and pregnancy. Recently, a potential clinical relevance of kisspeptins was noted with emerging interests in applied medicine. Some investigations are being carried out to develop these neuromodulators as a diagnostic marker in male and female infertility. Kisspeptin analogs could constitute a new therapeutic strategy based on hormonal manipulation of the hypothalamic-pituitary-gonadal axis. Conclusion: Further clinical trials are needed to provide the required evidence for the use of kisspeptin to trigger reproductive axis, gonadic functions and gametes differentiation guiding future clinical practice in couple infertility.

Published: January 2024

Background and Aims: In premenopausal and menopause women, a woman will start to experience mood problem and in more severe cases can cause depression. Researchers have connected the relation between hormonal changes that occur with the emersion of the symptom. In Indonesia, the awareness of the community to check themselves due to mental disorders is still quite low. This leaves many cases of depression have not been revealed. The main objective of this study was to find out the relation of menopause and depression by evaluating the subjects result of Hamilton Depression Rating Scale (HAM-D). Method: This research used thematic analysis of semi-structured interview based on Hamilton Depression Rating Scale (HAM-D). The collected data were analysed using IBM SPSS Statistic 23.0 for windows. The populations in this study are all women aged between 40-60 years, totaling 60 people. The choosing of the patients based on some criteria: 1) the data was taken from women aged 40 and above; 2) showing symptoms of premenopausal or menopause; 3) The researcher did not consider patient’s history of depression and other mental disorder; 4) That person have agreed to the informed consent. Results: Measurements Hamilton Depression Rating Scale (HAM-D) classified someone as suffering severe depression disorder if the test score is 24 and above, moderate depression if the score between 17-23, mild depression score is 8-16, and normal if the score is below 8. The statistically significant score is set up at p <0.05 if there is correlation between menopausal and depression. Women experiencing menopause tend to tend to experience depression; (Correlation Coefficient = 0.176); (p=0.179 or p>0.05) compared to those of women without menopause or premenopausal. Conclusion: The changes into menopausal phase increase the risk of being depressed even though it is low.
#370 : Hormone Replacement Therapy and Risk of Cardiovascular Diseases in Postmenopausal Women Aged 50-59 Years: A Systematic Review of Randomized Controlled Trials
Authors: Sutanto Reynardi Larope , Sugiyanto Michael , Wiweko Budi 
Published: January 2024

Background and Aims: Cardiovascular diseases are the leading cause of mortality worldwide. Due to declining estrogen levels, women are at higher risk of contracting cardiovascular diseases. Although hormone replacement therapy (HRT) has the potential to prevent cardiovascular diseases, its safety and efficacy are still controversial. The window of opportunity theory suggests that initiating HRT during the early stages of menopause could have the most significant benefits. This review aims to assess available evidence on the effects of HRT in preventing cardiovascular disease in early postmenopausal women aged 50-59 years old. Method: Systematic literature searching was conducted on four databases: Pubmed, EMBASE, EBSCOhost, and ProQuest. Using previously designed keywords, we searched for randomized controlled trials assessing the association between HRT and various cardiovascular outcomes. Critical appraisal was conducted using the Cochrane Risk of Bias 2.0. Results: Six post-interventional analyses from 2 randomized controlled trials with a total of 9,838 subjects were included. The review only assessed the data from subjects aged 50-59 years old without any known comorbidities. Despite varying statistical significance among studies, we observed a relatively consistent trend that estrogen-only HRT lowers the risk of cardiovascular events, thus supporting the window of opportunity theory. However, there was also an increase in the risk of cardiovascular events in estrogen-progesterone combination compared to placebo or estrogen-only HRT. Conclusion: By taking into account aspects of patient characteristics, age during first administration, regimens, and therapy duration, hormone replacement therapy has the potential to prevent cardiovascular diseases in early postmenopausal women aged 50-59 years old.
