What happens when blood levels of FSH fall off?

When blood levels of follicle-stimulating hormone (FSH) fall, it can lead to a decrease in the stimulation of ovarian follicles in females and spermatogenesis in males. In women, this may result in irregular menstrual cycles or decreased fertility, while in men, it could contribute to reduced sperm production and testosterone levels. Overall, low FSH levels can disrupt normal reproductive functions and hormonal balance.
