Drug information of Urofollitropin


Drug group:

Urofollitropin is a purified form of a hormone called follicle-stimulating hormone (FSH). This hormone is important in the development of follicles (eggs) that are produced by the ovaries in women. Urofollitropin is used together with other medicines to treat infertility in women with FSH deficiency. Urofollitropin is also used to help the ovaries produce multiple eggs for use in "in-vitro" fertilization. Urofollitropin alone will not cause ovulation (production of an egg by the ovaries). You will need to receive other medicines to stimulate ovulation.

Mechanism of effect

Stimulates ovarian follicular growth in women who do not have primary ovarian failure.


Used for the treatment of female infertility, urofollitropin or follicle stimulating hormone (FSH) stimulates ovarian follicular growth in women who do not have primary ovarian failure. FSH, the active component of urofollitropin is the primary hormone responsible for follicular recruitment and development.
