Although the level of evidence for the effects of vitamin D on vaginal health is low in our study , we concluded that vitamin D may improve the vaginal health of women , especially during menopause
Menopause is associated with the onset of climacteric symptoms due to low estradiol levels , which may cause insufficient maturation of the vaginal mucosa .
Vitamin D may regulate the growth and differentiation of cells that are adversely affected due to low estradiol levels , thereby restoring vaginal health .
The objective of this systematic review , the first on this subject , was to investigate the effect of vitamin D on the  vaginal health of menopausal women .
Role of Vitamin D in urogenital health of geriatric participants
Introduction : Role of Vitamin D is very well known for the functioning of many body organs . However , its role in the postmenopausal women in relation to various genitourinary disorders has been recognized recently . The main objective of this study was to evaluate role of Vitamin D in vaginal health , prolapse , bladder and bowel function , and bacterial vaginosis ( BV ) . Material s and Methods : This was a r and omized controlled study in which 200 geriatric female patients of 65–78 years of age divided into two groups comprising study and control group with 100 participants in each . Detailed obstetrical , gynecological , and clinical history was elicited . Detailed examination regarding the prolapse , urinary and bowel functions , and bacterial infections was done followed by follow-up of 3 and 6 months each . Chi-square and independent t-test used for data analysis . Results : Mean modified vaginal health index ( MVHI ) among patients with pelvic floor diseases was statistically significant with P = 0.0472 . There was a visible increasing trend in Vitamin D deficiency with increase in time since menopause ( P = 0.1193 ) . Patients with pelvic floor disease had mean Vitamin D statistically significant with P = 0.0462 . With increase in  Vitamin D levels , MVHI was found to be better . The association of mean Vitamin D levels among patients with urinary incontinence as compared to controls was significant with P = 0.0460 . Association of mean Vitamin D levels in patients with fecal incontinence and BV as compared to controls was not statistically significant with P = 0.6304 and 0.79 , respectively . Low Vitamin D levels were associated with high mean parathyroid hormone ( PTH ) levels statistically significant with P = 0.034 . MVHI was found to increase significantly with Vitamin D supplementation at 3 and 6 months ' follow-up . There was increase in Vitamin D and calcium levels and fall in serum PTH levels at 3 and 6 months . Conclusions : Vitamin D levels were associated with a decreased risk of pelvic floor disorders , improved MVHI in women in geriatric age group
