Female infertility Hormone replacement therapy
SustEN 100 Injection works by preparing the uterus for pregnancy and maintaining a healthy environment for fetal development. It thickens the uterine lining to support implantation and prevents contractions that could lead to early pregnancy loss. Additionally, it helps regulate the menstrual cycle and balances other reproductive hormones. In hormone therapy, it supports overall hormonal stability and helps manage symptoms related to hormonal imbalances.
