Human placenta extract injection, commonly known as Placentrex, is used in regenerative medicine for wound healing, gynecological conditions, and infertility support. It contains bioactive compounds such as peptides, amino acids, and growth factors that stimulate tissue repair, improve blood circulation, and reduce inflammation. Clinically, it is effective in treating chronic ulcers, burns, pelvic inflammatory disease, and ovarian cysts, while also enhancing endometrial receptivity in fertility treatments. In dermatology, it supports skin regeneration and is applied in oral submucous fibrosis and anti-aging therapies. Though generally safe, mild local reactions may occur, and its use during pregnancy is discouraged.
