Pregnyl®

Pregnyl® is an injectable, highly purified preparation of human chorionic gonadotropin. It mimics the normal surge of luteinizing hormone (LH) that occurs mid-way through a normal menstrual cycle, and causes ovulation to begin.

It is the next step after follicle stimulation with Follistim® AQ Cartridge (follitropin beta injection).  Although follitropin beta in the Follistim® AQ Cartridge causes the follicles to mature, it does not induce ovulation. Pregnyl® helps to induce ovulation and release the mature egg from the follicle.

For detailed instructions on using Pregnyl®, read the Pregnyl® Use Instructions.
