Vitamin D is a nutrient that plays a vital role in many aspects of health, including fertility. Studies have suggested that low vitamin D levels may be associated with an increased risk of infertility in both men and women.
In women, low vitamin D levels have been linked to ovulatory dysfunction, which can make it more difficult to conceive. One study found that women with low vitamin D levels were more likely to experience infertility and take longer to conceive compared to women with adequate vitamin D levels. Another study found that vitamin D supplementation improved pregnancy rates in women undergoing fertility treatments.
In men, low vitamin D levels have been linked to reduced sperm motility and abnormal sperm morphology. One study found that men with vitamin D deficiency had a higher rate of infertility compared to men with normal vitamin D levels.
