WebFSH inhibits cervical cancer development by regulating cell proliferation and apoptosis. FSH (10–40 mIU/mL) significantly inhibited ( P <0.05 or <0.01) the number of HeLa cells ( Figure 1A ). In subsequent in vivo and in vitro experiments, 20 mIU/mL FSH was used ( Figure 1A ). Mice were injected with HeLa cells. WebFurthermore, estradiol selectively inhibits FSH secretion by a direct action on the pituitary gland. This action of estradiol provides an explanation for the selective reduction in FSH responses to GnRH seen during pubertal maturation in girls and during the mid-follicular stage of the menstrual cycle. cyoa inflation https://gitamulia.com
