Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Vitamin A is scientifically recognized as essential for normal reproductive system function in both males and females. In females, vitamin A (retinol and its derivatives) is required for ovarian follicle development, placental development, and embryogenesis. Deficiency in vitamin A has been linked to infertility, impaired fetal development, and increased risk of maternal mortality. In males, vitamin A is critical for spermatogenesis; animal studies, particularly in rodents, show that vitamin A deficiency leads to degeneration of the seminiferous epithelium and cessation of sperm production. Human clinical data are more limited, but vitamin A deficiency is associated with increased risk of reproductive problems in populations with poor nutrition. The scientific evidence supporting vitamin A’s role is mostly based on mechanistic, observational, and animal studies, with limited but supportive data from human populations. Vitamin A’s importance is so well established that it is classified as an essential micronutrient for reproduction by health authorities such as the World Health Organization. However, direct supplementation to enhance fertility is not generally recommended unless deficiency is present, due to the risk of toxicity at high doses. In summary, vitamin A is scientifically validated as critical for reproductive health, though the strength of evidence in supplementing beyond normal dietary intake for reproductive benefits in well-nourished individuals is moderate.
