Insufficient testosterone level can be treated with anti-estrogen drugs, aromatase inhibitors and gonadotropins. 1. Anti-estrogen drugs: block the negative feedback inhibition of estrogen, promote the secretion of gonadotropins, and then stimulate the interstitial cells to produce testosterone, which is conducive to the production of spermatozoa, and play the role of testosterone, such as Tamoxifen. 2. Aromatase inhibitors: can inhibit the conversion of androgens into estrogens, increase testosterone levels, and promote sperm maturation and spermatogenesis. Testolactone, anastrozole and letrozole are commonly used in the clinic. 3. Gonadotropins: For the first time, they are used in patients with insufficient gonadotropin secretion. Studies have shown that gonadotropins can improve pregnancy and live birth rates in patients with idiopathic male infertility. The specific medication for testosterone needs to consult a medical professional and take the medication under medical supervision.
