Rating (out of 5): 3

Vitamin D is increasingly recognized for its roles beyond bone health, including its involvement in the reproductive system. Multiple scientific studies suggest that vitamin D receptors are present in reproductive tissues such as the ovaries, uterus, placenta, and testes. This has led researchers to investigate its influence on fertility and reproductive function in both men and women.

In women, vitamin D deficiency has been associated with conditions such as polycystic ovary syndrome (PCOS), endometriosis, and infertility. Some studies indicate that adequate vitamin D levels may support normal menstrual cycles, ovarian follicle development, and implantation. For instance, observational studies have found correlations between higher vitamin D status and better outcomes in assisted reproductive technologies, such as in vitro fertilization (IVF), including higher pregnancy rates.

In men, vitamin D may play a role in supporting healthy testosterone levels and sperm quality. Some research has observed positive associations between vitamin D status and semen parameters, though evidence from intervention trials is still limited and somewhat inconsistent.

Overall, while there is a growing body of scientific literature exploring the link between vitamin D and reproductive health, the evidence is not yet definitive or robust enough to warrant routine supplementation solely for reproductive health purposes. More controlled clinical trials are needed to establish clear recommendations. However, the presence of vitamin D receptors in reproductive tissues and initial clinical data provide moderate scientific support for its role in the reproductive system.
