Definition

Any recombinant form of the endogenously produced heterodimer glycoprotein luteinizing hormone (LH) normally made by the anterior pituitary gland, that can be used for the treatment of LH deficiency. Upon administration, recombinant LH mimics the biological activity of endogenous LH. In females, this triggers ovulation and the development of the corpus luteum. In males, LH stimulates Leydig cells to produce testosterone.
