HCG (Human Chorionic Gonadotropin) 10000 IU is commonly used in fertility treatments. It stimulates the production of hormones such as estradiol and progesterone in women, promoting ovulation and supporting pregnancy. Additionally, HCG is used in male infertility treatments to increase sperm production. The HP-hCG 1000 IU injection is a high-quality form of HCG that plays a vital role in regulating the reproductive system in both men and women.
