Merck announced that the Food and Drug Administration (FDA) has approved Gonal-f RFF Redi-ject prefilled pen, a new version of Gonal-f (follitropin alfa injection) prefilled pen. 

Gonal-f was initially approved in 2013 for the treatment of of female infertility and for the induction of spermatogenesis in men with hypogonadotropic hypogonadism without testicular failure. The recombinant human follicle-stimulating hormone (r-FSH) supplements or replaces naturally occurring FSH, which is essential to treat infertility. It stimulates ovarian follicular growth in women without primary ovarian failure.
