Folliculogenesis in response to exogenous stimulation by human urinary follicle stimulating hormone (huFSH) and human menopausal gonadotropin (hMG) was evaluated in the domestic queen (Felis catus). The role of LH and/or FSH in folliculogenesis was examined by measuring concentrations of estradiol 17 beta (E2) arid progesterone (P) in the serum. Additionally, changes in the number and size of follicles from before the administration of exogenous hormones to surgical oocyte collection were monitored. Findings indicated that in queens receiving huFSH or hMG followed by human chorionic gonadotropin (hCG) to induce ovulation, the numbers of follicles from 1 to 3 mm increased with statistical significance (P < 0.005) from before the initiation of treatment to surgical collection of oocytes. Although E2 Concentrations in cats receiving hMG increased above baseline by the third exogenous hormone injection, mean E2 concentrations did not increase in the groups that received both huFSH and hCG, or hCG only, until after the administration of hCG. This suggests that the exogenous administration of LH contained in both hMG and hCG was necessary for E2 to rise to levels associated with estrus.
