The researchers studied the levels of sexual hormones in the semen of men with fertility issues. They found that patients with low sperm count or no sperm had different hormone levels compared to men with normal sperm. Specifically, the levels of LH and FSH were higher in men with fertility issues, while the level of T was lower. These hormone changes may be linked to problems with sperm production and maturation. Understanding these hormone differences could help develop new treatments for male infertility.
