背景資料

Follicle stimulating hormone （FSH） is a hormone synthesised and secreted by gonadotropes in the anterior pituitary gland. FSH and LH act synergistically in reproductionIn women， in the ovary FSH stimulates the growth of immature Graafian follicles to maturation. As the follicle grows it releases inhibin， which shuts off the FSH production.
In men， FSH enhances the production of androgen-binding proteinby the Sertoli cells of the testes and is critical for spermatogenesis.
In both males and females， FSH stimulates the maturation of germ cells. In females， FSH initiates follicular growth， specifically affecting granulosa cells. With the concomitant rise in inhibin B FSH levels then decline in the late follicular phase. This seems to be critical in selecting only the most advanced follicle to proceed to ovulation. At the end of the luteal phase， there is a slight rise in FSH that seems to be of importance to start the next ovulatory cycle.
Like its partner， LH， FSH release at the pituitary gland is controlled by pulses of gonadotropin-releasing hormone（GnRH）. Those pulses， in turn， are subject to the estrogen feed-back from the gonads.

溶解建議

提供的人卵泡刺激素產品為白色無菌凍干粉末，凍干粉里不含有其它添加劑.推薦使用無菌的18MΩ的超純水來溶解，濃度不低于100ug/ml，便于后續(xù)稀釋.

保存建議

Lyophilized FSH although stable at room temperature for 3 weeks， should be stored desiccated below -18℃. Upon reconstitution FSH-beta should be stored at 4℃ between 2-7 days and for future use below -18℃. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please prevent freeze-thaw cycles.
