Vitamin A (as retinyl acetate) is scientifically validated as important for the reproductive system in both males and females. Vitamin A is essential for normal reproductive function. In females, it supports the development of oocytes (egg cells), embryonic development, and is necessary for proper placental formation and function. In males, Vitamin A is crucial for spermatogenesis (the production of sperm). Deficiency in Vitamin A has been shown in both animal and human studies to result in infertility, impaired spermatogenesis, and disrupted ovarian function. For example, seminal work in the 20th century demonstrated that Vitamin A-deficient male rats became sterile due to halted spermatogenesis, while supplementation restored fertility. In females, deficiency leads to impaired fertility and poor embryonic development. The World Health Organization recognizes Vitamin A as an essential micronutrient for reproductive health, particularly in populations at risk of deficiency. However, while Vitamin A is essential for normal reproductive system function, there is limited evidence that supplementation above recommended daily allowances improves fertility in well-nourished individuals. Excessive Vitamin A intake can also be teratogenic (cause birth defects) if taken in high doses during pregnancy. Thus, the use of Vitamin A to support the reproductive system is scientifically justified, but supplementation should be approached with appropriate caution and only to correct deficiencies.
