卵巢低反应专家共识

卵巢低反应(POR)是卵巢对促性腺激素(Gn)刺激反应不良的病理状态。POR诊断标准满足以下3条中的2条即可:1高龄(≥40岁)或存在卵巢反应不良的其它危险因素;2前次IVF周期卵巢低反应,常规方案获卵数≤3个;3卵巢储备下降[窦卵泡数(AFC)5~7个或抗苗勒管激素(AMH)0.5~1.1μg/L]。其病因主要与年龄、遗传和免疫因素、环境因素等有关。在IVF助孕中建议采用常规的Gn RHa长方案、Gn RHa短方案和Gn RHA方案进行促排卵,也可采用非传统的微刺激方案、自然周期方案等方法。另外,使用生长激素(GH)、雄激素(A)、雌激素、口服避孕药(OC)等及中医中药来预处理有利于患者治疗结局的改善。     

卵泡期长效长方案在卵巢储备良好但前次黄体期短效长方案助孕失败患者中的应用:一项自身对照研究

目的:探讨卵泡期长效长方案对卵巢储备功能良好但前次黄体期短效长方案助孕失败患者的妊娠结局是否有所改善。方法:回顾性分析106例前次黄体期短效长方案助孕失败后行卵泡期长效长方案再次助孕的卵巢储备功能良好(AFC5)患者212个周期的临床资料,按照促排卵方案分为黄体期短效长方案(A组)与卵泡期长效长方案(B组)。结果:Gn启动日E2值、hCG注射日E2值和子宫内膜厚度以及移植胚胎数组间比较均无统计学差异(P0.05)。B组Gn启动日、hCG注射日血LH值和早期流产率均显著低于A组(P0.001),而Gn使用总剂量、Gn使用天数、获卵数、MII卵数、MII卵率、2PN数、可移植胚胎数、胚胎种植率、生化妊娠及临床妊娠率均显著高于A组(P0.001)。结论:在卵巢储备功能良好但前次黄体期短效长方案助孕失败的女性中,再次助孕采用卵泡期长效长方案可显著提高获卵数及卵子质量,并显著提高妊娠率,降低早期流产率,是理想的治疗方案。     

基础FSH/LH比值及晚卵泡期LH水平对体外受精-胚胎移植结局的影响

目的:探讨患者基础FSH/LH比值及控制性超促排卵(COH)时降调后hCG注射日血清LH水平对IVF-ET结局的影响及与COH各参数的关系。方法:回顾性分析首次进行IVF/ICSI-ET助孕、应用GnRH-a长方案降调节的不孕妇女,共427个周期。结果:ROC曲线显示FSH/LH比值与IVF-ET临床妊娠率无明显相关性;FSH/LH≥2与FSH/LH<2组间虽然临床妊娠率无差异,但FSH/LH≥2组Gn用量增加,获卵数少,优质胚胎数少,存在统计学差异(P<0.05)。hCG注射日血清LH≥0.65IU/L者妊娠率(55.8%)明显高于LH<0.65IU/L者(24.6%)。结论:基础FSH/LH比值增高能较早反映卵巢储备功能并指导超排方案及Gn用量;降调节后卵泡晚期(hCG注射日)的LH水平过低(<0.65IU/L),将会导致临床妊娠率下降。     

黄体期改良超长方案在子宫内膜异位症患者IVF中的应用

目的:探讨改良后的黄体期超长方案降调节在子宫内膜异位症(EMs)和卵巢储备功能稍低患者行IVF治疗中的临床效果。方法:选取行IVF并确诊为EMs的患者112例,其中58例患者给予传统黄体期长效长方案降调节作为对照组,54例患者第1次降调节不理想后再次给予降调节者作为研究组,对比分析研究组和对照组患者的周期取消率、促性腺激素(Gn)使用量、Gn使用天数、获卵数、受精率、临床妊娠率、早期流产率及重度卵巢过度刺激综合征(OHSS)发生率。结果:研究组患者的临床妊娠率和受精率提高,周期取消率、流产率和重度OHSS发生率都有所降低。结论:改良黄体期长方案能够提高EMs患者的临床妊娠率和受精率,同时减少了周期取消率,是一种经济有效的降调节方案。

长方案超促排卵过程中LH变化趋势对IVF/ICSI-ET结局的影响

目的:探讨控制性超促排卵(COH)周期中LH变化趋势对体外受精/卵胞质内单精子注射-胚胎移植(IVF/ICSI-ET)结局的影响。方法:回顾性分析228个IVF/ICSI长方案周期,1按h CG注射日与降调节后Gn启动前血清LH水平的变化趋势,分为降低趋势组和升高趋势组;2将升高趋势组及降低趋势组根据COH中期与降调节后LH水平变化趋势分为A组和B组(升高趋势中的降低组和升高组),C组和D组(降低趋势中的降低组和升高组);3按照LH降低幅度将A组和C组分为A1组(下降幅度50%)和A2组(下降幅度≥50%)、C1组(下降幅度50%)和C2组(下降幅度≥50%),比较各组IVF/ICS-ET结局的差异。结果:1降低趋势组与升高趋势组获卵数、胚胎数、总的受精率、卵裂率、可利用胚胎率、优质胚胎率比较,差异均无统计学意义(P0.05),而胚胎种植率(26.09%vs 35.22%,P0.05)、临床妊娠率(45.11%vs 58.67%,P0.05)显著较升高趋势组低,早期流产率较升高组略高(26.08%vs 15.91%),但差异无统计学意义(P0.05)。2A组与B组、C组与D组相比较IVF/ICSI结局均无统计学差异。3 A1组、A2组的受精率、临床妊娠率、胚胎种植率、可利用胚胎率组间比较,差异均无统计学意义,但优质胚胎率A1组较高(65.48%vs40.68%,P0.05);C1组、C2组IVF/ICSI结局相比无统计学差异。结论:IVF/ICSI-ET长方案,h CG注射日较Gn启动前血清LH升高,有助于提高胚胎种植率、临床妊娠率,且在COH中期LH下降幅度50%,能显著提高优质胚胎率。故在COH的过程中适时添加LH,选择合适的血清LH水平启动COH,有助于改善助孕结局。     

卵巢正常反应不孕症患者体外受精不同长方案促排卵效果的研究

目的探讨卵巢正常反应不孕症患者体外受精/卵胞质内单精子显微注射(IVF/ICSI)促排卵时应用口服避孕药(OC)长方案和黄体中期长方案的促排卵效果及临床结局。方法选择接受长方案IVF/ICSI助孕的卵巢正常反应患者共4 677个周期;根据年龄分为≤35岁组和35岁组,不方便超声监测排卵或自然周期超声监测卵泡不破裂的患者共2 762个周期,应用OC长方案(OC组);自然周期超声监测正常排卵的患者共1 915个周期,应用黄体中期长方案(黄体中期组);常规行IVF/ICSI,比较上述不同年龄人群2种促排卵方案的临床和实验室相关指标。结果 (1)OC组促性腺激素(Gn)启动日雌二醇(E2)[≤35岁组:(24.63±10.62)ng/L,35岁组:(24.24±10.40)ng/L]和促黄体生成素(LH)水平[≤35岁组:(0.92±0.59)IU/L,35岁组:(0.82±0.66)IU/L]均明显低于黄体中期组[≤35岁组:(25.89±12.80)ng/L,35岁组:(25.71±10.93)ng/L;≤35岁组:(1.37±0.59)IU/L,35岁组:(1.01±0.70)IU/L](P0.05);(2)OC组人绒毛膜促性腺激素(h CG)注射日E2水平[≤35岁组:(4 143.8±2 769.9)ng/L,35岁组:(3 597.5±2 160.4)ng/L]和因卵巢过度刺激综合征(OHSS)行全胚冷冻率(≤35岁组:9.1%,35岁组:10.2%)均明显高于黄体中期组[≤35岁组:(3 850.8±2 092.4)ng/L,35岁组:(3 213.4±1 804.5)ng/L;≤35岁组:4.9%,35岁组:5.9%](P0.05),但h CG注射日的内膜厚度[≤35岁组:(10.75±2.25)mm,35岁组:(10.47±2.38)mm]却明显小于后者[≤35岁组:(11.62±2.43)mm,35岁组:(11.09±2.68)mm](P0.05);(3)在年龄35岁的OC组Gn总用量[(3 775.4±1 200.0)IU]和使用时间[(13.5±2.2)d]明显高于黄体中期组[(3 516.9±1 156.1)IU,(12.4±2.2)d](P0.05);(4)2种降调节方案患者的获卵数、ICSI成熟卵数、双原核(2PN)受精率、平均移植胚胎数、优质胚胎率和早期流产率均无明显差异(P0.05),但OC组的着床率(≤35岁组:41.4%,35岁组:25.5%)和临床妊娠率(≤35岁组:55.7%,35岁组:37.5%)明显小于黄体中期组(≤35岁组:46.7%,35岁组:31.4%;≤35岁组:65.6%,35岁组:46.9%)(P0.05)。结论 (1)OC长方案可加深垂体抑制,尤其是35岁的高龄患者需增加Gn用量才能达到与黄体中期长方案相似的促排卵效果;(2)OC长方案可能通过影响子宫内膜厚度及容受性而降低着床率和临床妊娠率;(3)OC长方案使h CG注射日E2水平更高,易诱发OHSS的发生。故对卵巢功能正常的不孕患者,IVF/ICSI助孕时尽量选择黄体中期长方案。     

减少GnRHa剂量对长方案促排卵卵巢反应性的影响

Effects of oral contraceptive pretreatment on IVF outcomes in women following a GnRH agonist protocol

Research questionDoes oral contraceptive pretreatment impact IVF–embryo transfer cycle outcomes in women following the gonadotrophin-releasing hormone agonist (GnRHa) protocol?DesignThis retrospective study was designed to compare cycle outcomes after oral contraceptive pretreatment versus the standard protocol in women within the GnRHa long protocol or the GnRHa short protocol. A total of 2052 women undergoing their first IVF treatment with the GnRHa long protocol and 3557 women with the GnRHa short protocol between 2012 and 2017 were enrolled.ResultsNo significant differences in the rates of clinical pregnancy (long protocol: 49.2% versus 46.7%; short protocol: 39.4% versus 38.0%) or live birth (long protocol: 44.3% versus 41.3%; short protocol: 32.8% versus 31.4%) after fresh embryo transfer were observed between the oral contraceptive group and the control group in either the long protocol or the short protocol.ConclusionsOral contraceptive pretreatment has no effect on IVF outcomes in either the GnRHa long protocol or short protocol.     

GnRHa flare and IVF pregnancy rates.

OBJECTIVES: GnRH agonist administered early in the menstrual cycle (flare) causes an endogenous discharge of FSH and LH. Flare has been used in conjunction with gonadotropin ovarian stimulation for IVF 'poor responders'. There is an ongoing controversy regarding whether flare protocols improve pregnancy rates in 'poor responders'. The current study was designed to compare a GnRHa flare protocol with long suppression GnRHa IVF in 'poor responders'. METHODS: Seventy-three newly diagnosed poor responders who failed long GnRHa suppression IVF attempts were compared retrospectively with 128 age-matched IVF patients previously known poor ovarian responders treated with a long GnRHa suppression protocol. 'Poor responders' consisted of patients with peak E(2) less than 1000 pg/ml and/or less than five mature follicles with diameter >15 mm on the day of hCG administration. Student's t-test was used to analyze the data and the chi-squared test was used to compare fertilization and pregnancy rates. RESULTS: The flare protocol produced higher peak E(2) levels (1647+/-747 vs. 720+/-258 mIU/ml, P<0.05) and a larger number of mature follicles (5.8+/-2.2 vs. 4.0+/-1.0 P<0.05) in the study vs. the control group. A 30% pregnancy rate was achieved during this second IVF attempt using GnRHa flare protocol in the study group vs. 37 in the control group (P>0.05, NS). CONCLUSIONS: A comparison between the flare protocol group and the age-matched control group of poor ovarian responders subject to down regulation protocol, revealed higher peak E(2) levels and more mature follicles, respectively. However, both groups yielded comparable pregnancy rates. The use of high dose gonadotropin treatment in our study groups seems to be the only explanation for their subsequent successful outcome. We concluded that GnRH agonist flare protocol does not result in better IVF outcome compared with long GnRH agonist suppression protocol in IVF poor responders.     

GnRH Antagonist Improved Blastocyst Quality and Pregnancy Outcome After Multiple Failures of IVF/ICSI–ET with a GnRH Agonist Protocol

BACKGROUND: To determine the efficacy of a gonadotrophin-releasing hormone (GnRH) antagonist, cetrorelix, in improving the quality of embryos and pregnancy outcome, we performed a study in patients with a history of multiple failures of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles with a GnRH agonist (GnRHa) long protocol. METHODS: Forty women with no live births after conventional IVF or ICSI embryo transfer (ET) and subsequent blastocyst transfer (BT) with a GnRHa long protocol entered this study. The treatment protocol consisted of a daily dose of clomiphene citrate 100 mg for 5 days and gonadotrophin injections daily from cycle day 4 onward. Cetrorelix, 0.25 mg/day, was started when the leading follicle reached 14 mm. Induction of ovulation was triggered with human chorionic gonadotrophin (HCG) (N = 36) or GnRHa (N = 4). It was possible to perform BT in 38 patients. RESULTS: Comparison of the results with the results for BT with the previous GnRHa protocol showed no significant differences in number of oocytes retrieved or the zygote- and blastocyst-development rate. With the cetrorelix protocol, however, number of patients whose embryos had developed to at least one expanded blastocyst on day 5 was significantly higher than with the GnRHa protocol (25 vs. 9) (p < 0.001), and 16 of the women became pregnant (42.1%), with 7 delivering 9 infants, 4 ending in abortion (25%), and 5 in progressing. CONCLUSIONS: The use of a GnRH antagonist in controlled ovarian hyperstimulation improves the outcome of pregnancy of patients with a history of multiple failure of IVF/ICSI-ET in a GnRHa protocol, most likely due to improvement of the quality of the blastocysts generated.     

改良超长方案在卵巢储备功能低下高龄患者中的应用

目的:探讨改良超长方案行体外受精-胚胎移植(IVF-ET)助孕的高龄(年龄≥40岁)且卵巢储备功能低下(窦卵泡3~7个)患者的治疗结局。方法:采用随机对照前瞻研究的方法,将行IVF-ET的120例高龄且卵巢储备功能低下患者随机分成:改良超长方案组(A组,n=55)和拮抗剂方案组(B组,n=65),比较A、B组间IVF-ET结局。结果:A组的Gn使用总量(3 955.2±1194.3 IU)、Gn使用天数(11.7±1.9 d)、hCG注射日E2水平(2 452.7±1 285.6 pg/ml),hCG注射日子宫内膜厚度(12.1±2.3 mm)均明显高于B组(分别为2 022.5±610.1 IU、9.1±1.7 d、1 257.7±696.0 pg/ml、11.3±2.0 mm),P<0.05;周期取消率、优质胚胎率、妊娠率、着床率、流产率、宫外孕发生率组间均无统计学差异(P>0.05)。A组hCG注射日LH水平(1.0±0.5 mIU/ml)及P/E2值(0.3±0.2)明显低于B组(3.4±2.4 mIU/ml及0.5±0.2),P<0.05。结论:改良超长方案经过GnRHa的预处理,使患者充分降调节,hCG注射日可以获得良好的LH水平、P/E2值及内膜厚度;而hMG的使用,既可降低患者费用,又可以适当补充LH,提高子宫内膜容受性。因此,对于高龄且卵巢储备功能低下的患者,改良超长方案是一个经济有效的治疗选择。     

Low dose gonadotropin-releasing hormone agonist treatments with early discontinuation for controlled ovarian hyperstimulation in an<Emphasis Type="Italic">in vitro</Emphasis> fertilization program

Aim:  The purpose of the present study was to investigate the applicability of a protocol for controlled ovarian hyperstimulation (COH) featuring early discontinuation of low dose gonadotropin-releasing hormone agonist (GnRHa) for ovulation induction for in vitro fertilization (IVF).
Methods:  Four hundred and eighty-seven women undergoing 555 IVF cycles were recruited into the study. Controlled ovarian hyperstimulation was achieved by using either a short protocol of low dose GnRHa (for 5 days only; groups 1 and 2) or a modified long protocol with early discontinuation of GnRHa (groups 3 and 4). Groups 1 and 3 received urinary follicle-stimulating hormone (FSH) and groups 2 and 4 received recombinant FSH. Oocyte retrieval was performed 34 to 36 h after human chorionic gonadotropin (hCG) injection, followed by embryo transfer 3 days later.
Results:  Luteinizing hormone (LH) levels on the hCG injection day were lower with the modified long protocol (groups 3 and 4) than with the short 5-day treatment (groups 1 and 2). There were higher LH levels in group 1 than in groups 2, 3 and 4, resulting in a worse fertilization rate and clinical pregnancy rate. There were no statistically significant differences between groups 2, 3 and 4 in the rates of fertilization, clinical pregnancy and delivery. A higher estradiol (E₂) level in group 3 than in groups 1, 2 and 4 resulted in a worse implantation rate.
Conclusion:  Early cessation of GnRHa may not induce a premature LH surge in controlled ovarian hyperstimulation, while a low dose also offers a useful alternative to a long protocol of IVF. Ovarian stimulation with recombinant follicle-stimulating hormone (rFSH) is considered to be favorable in this low dose GnRHa treatment. (Reprod Med Biol 2003; 2 : 25–30)
