HCG is prescribed to men for conditions like hypogonadism, where it helps stimulate the testes to produce more testosterone. It is also used to treat male infertility by boosting sperm production, and can help restore natural testosterone levels in men after steroid use or to prevent testicular atrophy.

HCG works by stimulating the testes to produce more testosterone and sperm. It mimics the action of luteinizing hormone (LH), which signals the testes to increase testosterone production, supporting both hormone balance and fertility.

When using HCG, men may notice improvements in testosterone levels, energy, mood, and libido. It can also help with fertility by increasing sperm count and quality, though results can vary depending on the individual and the condition being treated. Some may experience mild side effects, such as mood swings or water retention.
