Clinical Use
Lutropin alfa is the first pure human LH preparation and is of rDNA origin. According to
physicochemical and biological assays, it is indistinguishable from human LH of natural origin. It
is indicated for use in infertile women who are undergoing ART, specifically those with severe
LH deficiency. It is meant to be coadministered with follitropin alfa so as to stimulate follicular
growth in these women. When the follicles are of correct size, as determined by ultrasound
examination, hCG would be administered to stimulate ovulation.
