In 1901, Georg Kelling of Dresden, Germany, performed the first laparoscopic procedure in dogs, and, in 1910, Hans Christian Jacobaeus of Sweden performed the first laparoscopic operation in humans.[35] In the ensuing several decades, numerous individuals refined and popularized the approach further for laparoscopy. In patients with low gonadotropins and low estrogen, the treatment of choice is hMG, and the protocol is similar to that for patients with primary amenorrhea. This may take the form of miscarriages or extrauterine pregnancies. A vasectomy can be reversed, but reversals aren't usually successful. LH mainly functions to stimulate testosterone secretion from the Leydig cells of the testicle, while FSH stimulates Sertoli cells to facilitate germ cell differentiation.
