Leuprolide Acetate (Lupron) is related to a naturally occurring hormone called gonadotropin releasing hormone (GnRH). Leuprolide Acetate has also been used to treat endometriosis, uterine fibroids, early puberty, and as part of the process to stimulate multiple eggs for assisted reproductive technologies. The strength of Leuprolide Acetate is 1mg/0.2ml. Leuprolide Acetate is administered as a subcutaneous injection using insulin syringes. Insulin syringes are used because the measurement on the syringe is in units (i.e.: 10 units is equivalent to 0.1ml/cc). For the role it plays in assisted reproductive technologies, Leuprolide Acetate is used to reduce the amount of estrogen and testosterone in the body. This decrease in estrogen production will prevent ovulation and stop menstrual periods.
