简要总结
The purpose of this trial is to compare the efficacy and safety of the PPOS protocol to the GnRH antagonist protocol in patients with PCOS who are undergoing IVF/ICSI cycles.
详细描述
Polycystic ovary syndrome (PCOS) is a common metabolic dysfunction and heterogeneous endocrine disorder. It is the most common cause of anovulatory infertility, affecting approximately 10%-18% of reproductive age women worldwide.
It is usually characterized by a clustering of hyperandrogenism, hypersecretion of luteinizing hormone (LH) and hyperinsulinaemia, which could result in the arrest of ovarian follicular growth, oligo-ovulation or anovulation, menstrual dysfunction, hirsutism, infertility, pregnancy and/or neonatal complications.
Women with PCOS undergoing IVF or Intracytoplasmic sperm injection (ICSI) treatment because of infertility are increasing in number, and these patients have been well described, typically characterized by producing an increased number of oocytes but are often of poor quality leading to lower fertilization, implantation, and pregnancy rates and a higher miscarriage rate and incidence of ovarian hyperstimulation syndrome.
Increasing evidence raises the issue that impaired oocyte maturation and developmental competence in women with PCOS are possibly linked to abnormal endocrine/ paracrine factors, metabolic dysfunction and alterations in the intrafollicular microenvironment during folliculogenesis and follicle maturation.
Several clinical ovarian stimulation protocols have been used so far in women with PCOS undergoing IVF treatment to prevent a premature LH surge during controlled ovarian stimulation (COS); these primarily include gonadotropin-releasing hormone (GnRH) agonist or antagonist protocols.

研究组 & 干预措施
PPOS group
Patients will be coadministered with Human Menopausal Gonadotrophin (HMG) 150-225 international unit/day (IU/d) via intramuscular injection and oral DYG 20mg/d from menstrual cycle day 3 (MC3) to the day of triggering. The starting dose of HMG is 150IU/day for patients with a high antral follicle count >20 or slightly elevated basal FSH (7-10IU/L), and a daily dose of 225IU HMG is used for the other patients. The dose will be adjusted after day 5 of stimulation based on the ovarian response as assessed by serum hormone levels and transvaginal ultrasonography
