ABSTRACT
Antiphospholipid syndrome （APS） is an autoimmune disease characterized by the persistent presence of antiphospholipid antibodies， which are associated with thrombosis and pregnancy-related complications. APS may have adverse effects on female reproductive function by affecting ovarian function， endometrialization， and other mechanisms， and may lead to embryo implantation failure and pregnancy loss during in vitro fertilization and embryo transfer （IVF-ET） treatments. The routine screening and management of APS before IVF-ET in infertile populations remains controversial and requires individualized risk assessment and appropriate management measures to improve the success rate of assisted reproductive technologies （ART） and reduce maternal and fetal risks during pregnancy. This review summarizes the effects of APS on female infertility and outcomes of ART， as well as the management of the population affected by APS， providing new insights for clinical diagnosis and treatment.

ABSTRACT
OBJECTIVE@#To evaluate the influence of different transcutaneous electrical acupoint stimulation (TEAS) modes on ovarian responses and pregnancy outcomes in patients with infertility undergoing in vitro fertilization and embryo transfer (IVF-ET).@*METHODS@#Two hundred infertility patients undergoing IVF-ET were divided randomly into experimental groups (TEAS groups: E-I, E-II, E-III, and E-IV, 40 cases each group) and a control group (mock TEAS group, 40 patients) using the random number method. The patients in the experimental groups received TEAS treatment of 20, 30, 40 and 50 mA for the E-I, E-II, E-III and E-IV groups, respectively. The control group received a treatment of 5 mA. TEAS was applied at acupoints of Guanyuan (RN 4), Zhongji (RN 3), Sanyinjiao (SP 6), Zigong (EX-CA 1), and Taixi (KI 13), once a day for 30 min each time for a treatment period of 10-13 d. Treatment effect was assessed using the following indicators: endometrial thickness on the 6th day of gonadotropin treatment (GN6 day), endometrial thickness on the day on chorionic gonadotropin administration (HCG day), number of ovarian follicles on HCG day, number of ova captured, amount of estrogen required for each harvested ova, number of mature ova divided by the total number of ova, percentage of high-quality embryos, and clinical pregnancy.@*RESULTS@#Endometrial thickness in the experimental groups on the HCG day was significantly better than that of the control group after TEAS stimulation (P=0.01). TEAS exhibited a greater impact on the number of ova captured (P=0.003). However, the effect of TEAS stimulation on the high-quality embryo rate and clinical pregnancy in patients was not statistically significant (P>0.05).@*CONCLUSIONS@#TEAS is an effective method in improving the ovarian state. When the stimulus intensity was at 40 mA and above, it could be helpful to improve the patient's endometrial condition and endometrial receptivity and to retrieve more oocytes.

Objective: To investigate the effects of gonadotropin-releasing hor-mone-antagonist (GnRH-ant) on the proportion and toxicity of mice uterine nature killer (uNK) cells during implantation window. Methods: Sixteen C57BL/6 mice were randomly divided into GnRH-ant group and control group, with 8 mice in each group. From the 3rd day of the estrous cycle, GnRH-ant (1.5 μg/100 g) was injected intraperitoneally into the mice of the GnRH-ant group for 7 days continuously, and the control group was injected with the same volume of normal saline at the same time point. On the 7th day, the mice of the two groups were injected with human menopausal gonadotropin (40 U/100 g). The next day, they were injected with human chorionic gonadotropin (100 U/100 g) and sacrificed after 48 h. The uterus tissues were taken out for primary digestion to obtain single-cell suspension. Flow cytometry was used to analyze the proportion of uNK cells and the expression levels of toxicity molecules perforin (Pf) and granzyme B (Gz-B). Results: Compared with the control group, the proportion of uNK cells in GnRH-ant group increased (P=0.000), the proliferation level increased (P=0.000), the apoptosis level decreased (P=0.004), and the expression of toxicity molecules Pf (P=0.000) and Gz-B (P=0.034) were up-regulated. Conclusion: GnRH-ant may up-regulate the proportion of uNK cells and enhance their toxicity in the implantation window period of mice.
ABSTRACT
Objective • To compare the pregnancy outcomes between the patients undergoing single embryo transfer and double embryo transfer by in vitro fertilization and embryo transfer, and analyze the influencing factors. Methods • From Jan. 2011 to Jun. 2016, women who underwent single embryo transfer or double embryo transfer with in vitro fertilization and embryo transfer and successfully conceived in Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine were followed up to the pregnancy outcomes. According to the number of embryo transfer, the patients were divided into single embryo transfer group and double embryo transfer group. Univariate analysis (t test, Chi-square test) and multivariate Logistic regression analysis were used to compare the pregnancy outcomes between two groups, and analyze the influencing factors of adverse outcomes. Results • A total of 19 030 patients (98.69%) were followed up to the pregnancy outcomes. Stratified analysis showed that there were significant differences in the composition of pregnancy outcomes (P=0.000) and the number of live births (P=0.000) between two groups. For the neonatal birth quality, the infants born by the patients with single embryo transfer had higher birth weights than those born by the patients with double embryo transfer (P=0.000), and the proportions of newborns with low birth weights and full-term newborns with low birth weights were higher among the patients with double embryo transfer compared to those with single embryo transfer (P=0.000). In addition, there was no statistically significant difference in he incidence of birth defects between the infants born by the patients with single embryo transfer and double embryo transfer. Multivariate Logistic regression analysis showed that the risk of abortion or labor induction among the patients with double embryo transfer was higher than those with single embryo transfer with age, infertility causes and embryo type adjusted (OR=0.88, P=0.025). Conclusion • The risk of adverse pregnancy outcomes is higher among the patients with double embryo transfer than those with single embryo transfer.

ABSTRACT
[Objective] To investigate the effects of different doses of gonadotropin releasing hormone agonist (GnRH-α) on the down-regulation of normal ovarian reserve,and compared the down-regulation level as well as the clinical outcome of in vitro fertilization and embryo transfer (IVF-ET) cycles.[Methods] This RCT study included 63 infertility couples of age＜35 yrs.women with normal ovarian reserve function who were intended to received GnRH-α long protocol treatment.Of the 63 women were randomly divided into three groups according to the dose of triptorelin,21 received daily 0.05 mg short-acting GnRH-α,21 received daily 0.1 mg short-acting GnRH-α,while 21 received reduced-dose depot of 1.25 mg GnRH-αt.[Results] In the three groups,the average duration of down-regulation reached after injection of GnRH-α,the level of LH and E2,the total number of antral follicles,the number of antral follicles of ＜4 mm and 8～9 mm were similar.The serum follicle-stimulating hormone level on the day of gonadotropin initiation were significantly higher in the two short-acting groups compared with the long-acting group [(3.92 ± 1.12) U vs.(3.03 ± 1.14) U vs.(2.05 ± 1.12) U,P＜ 0.001].Four hours after the GnRHa injection,the serum FSH,LH levels were higher in short-acting 0.05 mg group than the short-acting short-acting 0.1 mg group.Both number of days of gonadotropin stimulation and gonadotropin doses were similar in three groups.On the day of hCG administration,the numbers of 14-18mm diameter follicles [(3.91 ±2.12) vs.(5.81 ±3.55) vs.(6.43±3.39),P＜0.001] as well as the proportion of follicles with diameter ≥18 mm/≥10 mm [(33.1％± 13.2％) vs.(24.0％±12.4％) vs.(30.1％±12.2％),P＜0.05],were both statistically significant different in three groups.Although serum LH level on hCG day was significantly increased in 0.05 mg group [(2.47±1.33) U vs.(1.80±0.69) U vs.(1.43±0.53) U,P＜0.05].No premature LH surge and premature ovulation was observed.The number of retrieved oocyteswas significant different [(10.14±4.80) vs.(11.51±2.42) vs.(12.79±2.73),P＜0.05].However,no significant differences was found regard to the number of MII oocytes,and the serum estrogen level per egg was significant higher in 0.05 mg group [(282.33±42.13) U vs.(221.62±32.02) U vs.(200.03±37.89) U,P＜0.001].The live birth rate (LBR) of these three groups in fresh cycles were 61.9％,55.0％,and 50.0％,respectively.The cumulative LBR were 85.7％,76.2％,and 75.0％,respectively.A increased trend was observed in the clinical pregnancy rate,cumulative clinical pregnancy rate and cumulative LBR in 0.05 mg group than the other two groups.[Conclusion] For women with normal ovarian reserve,as the GnRH-α dosage decreased,the down-regulation of pituitary reduced,while serum LH levels on the day of hCG trigger increased.The number of oocytes retrieved was decreased,the proportion of cycles which retrieved ＞ 15 oocytes was also lower.However,the average estrogen level per egg was significant increased,and a better clinical outcome of IVF-ET was received.
ABSTRACT
The impact of prior cesarean section (CS) on the pregnancy and neonatal outcomes of in vitro fertilization and embryo transfer (IVF-ET) was investigated.A retrospective analysis was performed on 144 patients with prior CS between January 2013 and December 2015.The pregnancy,delivery,and neonatal outcomes of patients who had previous CS delivery and received IVF-ET were analyzed.The control group comprised 166 patients who had only previous vaginal delivery (VD) and received IVF-ET during the same period.The results showed that the basal follicle stimulating hormone level,estradiol level on human chorionic gonadotropin (hCG) day,gonadotrophin dosage,duration of stimulation,retrieved oocytes,fertilization rate,high-quality embryo rate,multiple birth rate,abortion rate and ectopic pregnancy rate had no significant difference between the two groups (P＞0.05).The pregnancy rate (40.28％ vs.54.22％) and implantation rate (24.01％ vs.34.67％) were significantly lower (P＜0.05),and the ratio of embryo difficulty transfer (9/144 vs.0/166) was significantly higher in CS group than in VD group.The risk of pernicious placenta previa and postpartum hemorrhage in twin deliveries was significantly increased in CS group as compared with that in VD group (P＜0.05),and gestational age and neonatal birth weight were significantly reduced in twin deliveries as compared with singleton deliveries in both groups (P＜0.05).It was suggested that the existence of CS scar may impact embryo implantation and clinical pregnancy outcome,and increase the difficulty of ET.We should limit the number of transfer embryos to avoid multiple pregnancies and strengthen gestational supervision in patients with cesarean scar.
ABSTRACT
Objective To investigate the influence of ovarian arterial blood flow index on pregnancy outcomes in patients undergoing in vitro fertilization and embryo transfer (IVF-ET).Methods Totally 136 infertile patients undergoing IVF-ET from February 2014 to April 2016 were divided into pregnant group and non-pregnant group.The monitoring through transvaginal B of two groups for chorionic gonadotropin (HCG) day and ovarian artery resistance index (RI),pulsatility index (PI) and umbilical artery diastolic flow velocity height ratio (S/D) on 2nd day of menstruation (M2) was conducted.The difference of blood flow indexes in two groups was analyzed.Results Compared with those in non-pregnant group,RI,PI and S/D in pregnant group were decreased on M2,and the difference was statistically significant (P ＜ 0.05).RI and PI were also decreased significantly on HCG day,and the difference was statistically significant (P ＜ 0.05),but S/D showed no significant changes (P ＞ 0.05).RI and PI decreased significantly on HCG day in two groups (P ＜ 0.05) when compared with those on M2,but in non-pregnant group,the comparison of S/D on HCG day showed no statistical significance (P ＞ 0.05).Conclusions There is close relationship among RI and PI of ovarian artery and ovarian reserve function.RI and PI are effective indexes to predict outcomes in IVF-ET,and provide scientific basis for the preparation and treatment for IVF-ET.
ABSTRACT
[Objective]To compare early serum beta-human chorionic gonadotropin (β-hCG) levels after cleavage or blastocyst embryo transfers (ET) in predicting pregnancy outcome.[Methods]A total of 2421 IVF-ET cycles in our center performed from June 2010 to May 2015 and resulted in clinical intrauterine pregnancies were analyzed retrospectively. The predictive value was compared betweenβ-hCG on day 14 after cleavage ET andβ-hCG on day 12 after blastocyst ET.[Results]Serumβ-hCG levels of patients re?sulted in clinical intrauterine pregnancies were significantly higher with blastocyst ET compared with cleavage ET. This significant dif?ference was also existed in patients resulted in miscarriage, ongoing pregnancy (OP) or live birth (LB). However, this significant differ?ence was only existed in frozen embryo transfers. For a frozen cleavage ET, the cut-off value was 475 U/L (sensitivity 79%, specificity 61.3%) in predicting LB. For a frozen blastocyst ET, the cut-off value was 575 U/L (sensitivity 74.9%, specificity 59.2%) in predicting LB.[Conclusion]In frozen embryo transfers, early serumβ-hCG level after blastocyst ET is higher than cleavage ET. The cut-off val?ue in predicting pregnancy outcome is different according to the stage embryo transferred. Early serum β-hCG can effectively predict live birth after blastocyst or cleavage ET.

ABSTRACT
Objective To compare the embryo development and pregnancy outcomes of patients by using two different 17?gauge aspiration needles in transvaginal ultra?sound guided oocyte retrieval. Methods A retrospective study was performed to analysis the embryo development and pregnancy outcomes of patients by using different oocytes aspiration needle:import needle(group A)and domestic needle(group B),including puncture follicles,oocytes rate,cleavage,available embryos,high?quality embryo,the total fertility rate,bleeding, moderately severe OHSS incidence,pregnancy rate,embryo implantation rate and abortion rate,etc. Results There was no significant statistical difference in the two different ovum aspiration needles. Conclusion The embryo development and pregnancy outcomes were similar with both needles. Each needle has its advantages and flaws in transvaginal ultra?sound guided oocyte retrieval ,and we should make a comprehensive choice weighing the practical situation of patients,cost,effectiveness and the doctors' preferences.
ABSTRACT
In recent years,assisted reproductive technology(ART)is developing rapidly,especially in vitro fertilization and embryo transfer(IVF-ET)technology.The rate of clinical pregnancy in our country is about 40％,and how to improve the rate of clinical pregnancy of IVF-ET has been the focus of the scholars research content.Environmental factors including culture system,temperature,humidity,pH value and volatile organic compounds,all of these can affect the success of IVF-ET.Now the common environmental factors affecting IVF-ET research progress were reviewed as follows.
ABSTRACT
In vitro fertilization and embryo transfer(IVF-ET) technology is one of the important means to treat infertility in recent years,although it had made remarkable progress in the field of reproductive medicine,but IVF-ET pregnancy success rate is not very ideal,the reasons that influent the success of IVF-ET include both parents donor of various unfavorable factors and stimulate ovulation itself produces all sorts of malpractices,its influence factors are complicated.In recent years,how to reduce the adverse factors affecting IVF-ET,to improve the success rate of pregnancy of IVF-ET has become the hot topics in the study of domestic clinical intervention in IVF-ET,and the domestic research shown that the quality of the follicle and endometrial environment is the key to determine the success of IVF-ET.
ABSTRACT
<p><b>Objective</b>To explore the prevalence of anxiety and its inducing factors in men undergoing in vitro fertilization and embryo transfer (IVF-ET).</p><p><b>METHODS</b>We randomly selected 202 men undergoing IVF-ET in the Infertility and Reproduction Center of the Second Xiangya Hospital of Central South University. On the first day of the IVF-ET cycle, we completed an investigation among the men using a self-designed questionnaire, Self-Rating Anxiety Scale (SAS), Social Support Rating Scale (SSRS), and 3 subscales (marital satisfaction, husband-wife communication, and sexual relationship) of Olson Marital Inventory.</p><p><b>RESULTS</b>Mild anxiety was found in 55 (27.2%) of the included men while the other 147 (72.8%) were non-anxiety males. Compared with the non-anxiety group, the anxiety group showed significant decreases in the total SSRS score (38.65±4.87 vs 36.44±4.21), objective support score (9.22±1.82 vs 8.36±1.18), and utility degree of social support score (6.89±1.50 vs 6.24±1.61) on the first day of the treatment cycle (P<0.01) as well as in the total scores of marital satisfaction (103.04±9.97 vs 96.89±9.90), husband-wife communication (32.29±4.24 vs 30.56±5.43), and sexual relationship (38.03±5.27 vs 34.20±4.41) (P<0.05). There were statistically significant differences in the incidence rate of anxiety in the men with different housing conditions, monthly incomes, treatment costs, attitudes towards IVF-ET, pressure from social opinion, status of parenthood (P<0.01). Multivariate logistic regression analysis indicated that the major factors associated with anxiety included the attitude towards IVF-ET, pressure from social opinion, and sexual relationship in the men undergoing IVF-ET (P<0.05).</p><p><b>CONCLUSIONS</b>The incidence rate of anxiety is high in males undergoing IVF-ET and it is associated with various factors. Psychological aid is needed to these male patients from the staff of the reproduction center.</p>
ABSTRACT
<p><b>Objective</b>To investigate the effects of the DNA fragmentation index (DFI) and malformation rate (SMR) of optimized sperm on embryonic development and early spontaneous abortion in conventional in vitro fertilization and embryo transfer (IVF-ET).</p><p><b>METHODS</b>We selected 602 cycles of conventional IVF-ET for pure oviductal infertility that had achieved clinical pregnancies, including 505 cycles with ongoing pregnancy and 97 cycles with early spontaneous abortion. On the day of ovum retrieval, we examined the DNA integrity and morphology of the rest of the optimized sperm using the SCD and Diff-Quik methods, established the joint predictor (JP) by logistic equation, and assessed the value of DFI and SMR in predicting early spontaneous abortion using the ROC curve.</p><p><b>RESULTS</b>The DFI, SMR, and high-quality embryo rate were (15.91±3.69)%, (82.85±10.24)%, and 46.53% (342/735) in the early spontaneous abortion group and (9.30±4.22)%, (77.32±9.19)%, and 56.43% (2263/4010) respectively in the ongoing pregnancy group, all with statistically significant differences between the two groups (P<0.05 ). Both the DFI and SMR were the risk factors of early spontaneous abortion (OR = 5.96 and 1.66; both P< 0.01). The areas under the ROC curve for DFI, SMR and JP were 0.893±0.019, 0.685±0.028, and 0.898±0.018, respectively. According to the Youden index, the optimal cut-off values of the DFI and SMR obtained for the prediction of early spontaneous abortion were approximately 15% and 80%. The DFI was correlated positively with SMR (r= 0.31, P<0.01) but the high-quality embryo rate negatively with both the DFI (r= －0.45, P<0.01) and SMR (r= －0.22, P<0.01).</p><p><b>CONCLUSIONS</b>The DFI and SMR of optimized sperm are closely associated with embryonic development in IVF. The DFI has a certain value for predicting early spontaneous abortion with a threshold of approximately 15%, but SMR may have a lower predictive value.</p>
