HCG Human Chorionic Gonadotropin 5000 IU injection is a hormone therapy widely used for treating infertility in women by inducing ovulation and supporting assisted reproductive techniques like IVF, and for male hypogonadism to boost sperm production and testosterone levels. In young boys, it can help correct undescended testicles when caused by hormonal deficiency. The injection works by mimicking the luteinizing hormone, which enables egg release from the ovaries and supports normal reproductive functions in both sexes. It is always administered under the supervision of a physician, who customizes the treatment plan to match the medical condition and therapeutic goals.
