Can acne drug or hormone shots help men with low sperm count?
Disease control By invitation onlyThis study tests two treatments—isotretinoin (an acne medication) and hCG (a hormone)—to see if they can help men with low or no sperm count produce moving sperm. About 100 men aged 19 to 50 will take one of the drugs for three months. The goal is to find new options for male inf…
