促性腺激素在卵泡的生长发育、募集、选择、优势化及排卵过程中起重要作用,已广泛应用于超促排卵中。然而如何安全、有效、经济的使用促性腺激素是生殖医学研究的热点。FSH使用的时间应根据患者卵巢功能的状态和所需获卵数的多少与用途而定。增加FSH的起始剂量和第2周期的剂量不一定能增加卵巢的反应性和妊娠率。检查FSH/LH比值更能筛选出基础内分泌在正常范围内的育龄妇女中处于早期卵巢功能减退的患者,给予适当的补充,但是FSH和LH都有自己的阈值,具体数值到目前为止还没有完全定论。 Gonadotropins play an important role in follicular growth and development, recruitment, selection, predominance and ovulation, and have been widely used in ovulation induction. However, how to use gonadotropin safely, effectively and economically is the hot point of reproductive medicine research. FSH use of time should be based on the status of patients with ovarian function and the number of oocytes and use required may be. Increasing the initial dose of FSH and the dose of the second cycle may not necessarily increase ovarian reactivity and pregnancy rates. FSH / LH ratio screening more screened endocrine within the normal range of women of childbearing age in early ovarian dysfunction in patients with appropriate supplementation, but FSH and LH have their own threshold, the specific value has not yet been completely Conclusion.
