Objective:To figure out the clinical factors contributing to the oocytes utility rate (OUR) of high responders in in vitro fertilization (IVF)-embryo transfer treatment.Methods:OUR was defined by the number of usable embryos for transfer and (or) cryopreservation divided by the number of oocytes retrieved in a freeze-all cycle. The cycles with ≥15 eggs were included from January 2013 to December 2019. Those with OUR at the top 10% (Group A) and the bottom 10% (Group B) were picked and compared for patients′ characteristics, parameters relating to ovary stimulation and pregnant outcomes. Multifactorial logistic regression was applied to reveal the risk factors affecting OUR in them.Results:A total of 43 patients were included in Group A (OUR: 77.4%, 601/776) and 47 for Group B (OUR: 11.9%, 104/874). Previous IVF/intracytoplasmic sperm injection (ICSI; OR=0.10, 95% CI: 0.01-0.81) and endometriosis ( OR=0.16, 95% CI: 0.03-0.84) were negative factors for OUR ( P<0.05); dual suppression protocol ( OR=3.74, 95% CI: 1.06-26.86) and longer days of stimulation ( OR=3.24, 95% CI: 1.25-8.42) were protective factors in terms of ovarian stimulation ( P<0.05), on contrary to that, any decline of estradiol during the stimulation led to poorer OUR ( OR=0.16, 95% CI: 0.04-0.64). Although two groups had similar quantities of eggs and metaphase of meiosis Ⅱ (MⅡ) oocytes, distinguished cumulative clinical pregnancy rate and cumulative live birth rate were seen in Group A and group B respectively [95.3% (41/43) vs 40.4% (19/47) and 90.7% (39/43) vs 31.9% (15/47), all P<0.01]. Conclusions:High responders with attempted IVF/ICSI and endometriosis should be considered as risk factors for OUR. Over ovarian stimulation, dual suppression and a slightly longer stimulating duration could be tried; besides, estradiol decline should be prevented for a better OUR.

OBJECTIVETo observe the therapeutic efficacy and safety of gonadotropin-releasing hormone agonist (GnRHa) combined Wenshen Xiaozheng Decoction (WXD) in auxiliary treating endometriosis after laparoscopy.
METHODSOne hundred and thirty-four endometriosis patients with confirmative pathological diagnosis were assigned to three groups depending on whether they would receive adjuvant therapy or Chinese medicine treatment, i.e., the control group, the observation 1 group, and the observation 2 group. The 22 patients in the control group received no adjuvant therapy after laparoscopy. The 42 patients in the observation 1 group were treated with GnRHa 3.6 mg by subcutaneous injection starting from the 1st day to the 5th day of menstruation, once per 28 days. The 70 patients in the observation 2 group were treated with GnRHa 3.6 mg by subcutaneous injection in combination with WXD starting from the 1st day to the 5th day of menstruation, once per 28 days. They also took WXD for 7 doses, one cycle per every 28 days. The treatment lasted for three to six months. Serum levels of estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and cancer antigen 125 (CA125), as well as clinical efficacy, and adverse drug reactions were observed before and after treatment.
RESULTSThere was statistical difference in serum levels of E2, FSH, or LH between the control group and the observation 1 and 2 groups (P < 0.05). There was no statistical difference in serum levels of E2, FSH, or LH between the observation 1 group and the observation 2 group (P > 0.05). There was statistical difference in the clinical efficiency among the 3 groups (P < 0.05). There was statistical difference in the pre-post difference of CA125 levels among the three groups (P < 0.01). Compared with the control group, there was no statistical difference in the pre-post difference of CA125 levels between the observation 1 group and the observation 2 group (P > 0.05). No obvious adverse reaction occurred during the treatment.
CONCLUSIONSGnRHa combined WXD showed confirmative clinical efficacy in treating endometriosis after laparoscopy. It also could lower serum levels of E2, FSH, and LH levels. So it was an ideal solution for treatment of endometriosis.
