Serial Progesterone Level Measurements During the Menstrual Cycle in Subfertile Women

Study Overview
=================
Brief Summary
-----------------
Ovulatory dysfunction is identified in 15% of all infertile couples and it accounts for 40% of female infertility. Ovulatory dysfunction may be more subtle in women with regular menses. Detecting the day of ovulation is necessary for optimizing natural conception, diagnosis of cycle disturbances and also timing for embryo transfer in natural cycle frozen-thawed embryo transfers. In order to diagnose ovulatory dysfunction, ovulation physiology and change of reproductive hormones during the menstrual cycle should be understood. In the present study we aimed to evaluate serial serum hormonal cut-off levels referenced to ovulation in subfertile women with regular menses.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| subfertile women<br>Subfertile women with regular menses (menstrual cycle length range from 21 to 35 days) will be examined by transvaginal ultrasonography at menstruation, before the anticipated date of ovulation and after ovulation. Serum hormone levels will be measured at menstruation, before ovulation and after ovulation with a serial manner. | Diagnostic Test: Serum progesterone levels<br>* In order to show change of serum progesterone levels, serial venous blood sampling will be done and also transvaginal ultrasonography will be performed to show ovulation.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of serum progesterone levels referenced to ovulation | Serum progesterone levels will be measured when dominant follicule is 17 mm in diameter and then serial measurements of hormones will be done and ovulation will be detected both hormonally and ultrasonographically. The range of serum progesterone will be reported referenced to ovulation. | Progesterone levels will be measured serially when dominant follicule reaches 17 mm in diameter and after that 1-2 days interval until to ovulation; 1 week after ultrasound and hormone-detected ovulation | 
| Change of reproductive hormone levels referenced to ovulation | Serum estradiol and luteinising hormone (LH) levels will be measured when dominant folicule is 17 mm in diameter and then serial measurements of hormones will be done and ovulation will be detected both hormonally and ultrasonographically. The ranges for serum hormones will be reported. | Estradiol and LH levels will be measured serially when dominant follicule reaches 17 mm in diameter and after that 1-2 days interval until to ovulation. |
