Used for triggering ovulation in women with anovulation or oligo-ovulation and for assisted reproductive techniques.
How It Works
Ovidrel Pen works by stimulating the ovaries to release eggs after other medications have been used to promote follicle development.
Good to know: Ovidrel is not addictive.
