Human menopausal gonadotropins Crowe discovered that the gonads were under the control of the anterior hypophysis. [175] Zondek and Aschheim discovered that FSH and LH were responsible for the development of the gonads in immature animals and confirmed Crowe's work. [135, 136] In the 1930s, ovulation induction was attempted by using gonadotropins from a mare, but its use was discontinued because of the development of antibodies. [176, 177] Borth et al demonstrated the effect of FSH and LH extracted from menopausal urine. [178, 179] Gemzell reported the first ovulation induction using human pituitary gonadotropin in 1958, and the first pregnancy was reported in 1960. [180, 181] Lunenfeld reported preliminary results using hMG; however, in 1963, it was definitely established as a real ovulation induction agent. [182, 183, 184] Human menopausal gonadotropin (hMG [eg, Repronex, Menopur]) contains 75 U of FSH and 75 U of LH per mL, although the concentration may vary among batches (ranges from FSH at 60-90 U and LH at 60-120 U). This is caused by hormonal issues like thyroid hypo- or hyperfunction, hyperprolactinemia, or polycystic ovarian syndrome (PCOS) — all of which can lead to infertility.  Absence of periods: Temporary life stress or overexercising may cause you to occasionally skip a period.
