Follicle-stimulating hormone (FSH) administration is effective in patients with hypogonadotropic hypogonadism, which suggests it might be useful in patients with oligozoospermia and normal FSH levels. Although, many studies have evaluated the efficacy of FSH in these patients, in this Perspectives article, the authors argue that FSH can be effective in idiopathic oligozoospermic men if patients are carefully selected.
