FSH and eCG impact follicles development and expression of ovarian FSHR and caspase-9 in mice.

ABSTRACT: The study aimed to investigate the effects of FSH and eCG on the ovarian and follicular development, expression levels of FSHR and caspase-9 of ovaries in vivo. One hundred and five prepuberty mice were allocated into FSH-1, FSH-2, FSH-3, eCG-1, eCG-2, eCG-3 groups and control group (CG). Mice in FSH-1, FSH-2 and FSH-3 were intramuscularly injected with 5, 10 and 20 IU FSH twice (on day 0 and 4), respectively. Mice in eCG-1, eCG-2 and eCG-3 were intraperitoneally injected with 10, 20 and 40 IU eCG on day 0 and 4. Mice in the CG were injected with 0.5 ml normal saline on day 0 and 4. Left and right ovaries of each mouse were dissected aseptically on days 7, 14 and 21, respectively. The results showed that on days 14 and 21 the ovarian sizes and follicle numbers of FSH-3 and eCG-3 gro
