A study recently published in the European Journal of Endocrinology has found that sunshine can promote fertility in both men and women.
The fertility-boosting effect is believed to be a result of increased production of Vitamin D.
Vitamin D is important in maintaining sex hormone levels in both men and women.
Men experience an increase in testosterone levels following sun exposure. Testosterone is essential for sperm production.
The sun boosts progesterone and estrogen in women by 13% and 21%, respectively, which are important for the regulation of female menstrual cycles.
