Objective To evaluate the influence of psychological intervention on pregnancy rate of in vitro fertilization-embryo transfer.Methods Using the key words,including in vitro fertilization-embryo transfer and psychological,the data were retrieved from CNKI,CBM,VIP,Wanfang and PubMed.The quality of eligible studies was evaluated by two reviews independently and Meta-analysis was conducted on studies.Results Totally thirteen Chinese studies and three foreign studies were included.Conclusions Psychological intervention using in the process of in vitro fertilization-embryo transfer can improve the pregnancy rate,which is worthy of clinical application.

In recent years, the freeze-all strategy has been widely adopted and applied. However, with the exception of age, the factors that affect the outcomes of frozen embryo transfer are still unclear. Therefore, the identification and mitigation of factors that influence the live birth rate after frozen embryo transfer is a good way to increase the "take-home-baby" rate of frozen embryo transfer. The objective of this study was to identify factors affecting the live birth rate after cleavage-stage frozen embryo transfer in young ovulatory women. This was a secondary analysis from a previously published multicenter randomized controlled trial (ChiCTR-IOR-14005406) that was originally designed to compare the live birth rate and perinatal complications after fresh embryo transfer to those after frozen embryo transfer among ovulatory women. This study was carried out using a portion of the data from the original randomized controlled trial, which included 917 young women who underwent cleavage-stage frozen embryo transfer. The 16 clinical candidate variables potentially affecting the live birth rate after frozen embryo transfer were analyzed. Univariable analysis and multivariable analysis were performed to assess the relationship between predictive factors and outcomes, with the aim of identifying independent predictors of live birth after frozen embryo transfer. In this study, the live birth rate was 53.0% (486/917). Three independent predictors were ultimately identified as the main factors affecting the live birth rate of ovulatory young women. Infertility duration [odds ratio (OR): 0.933, 95% confidence interval (CI): 0.876-0.995, p = 0.033], endometrial thickness before frozen embryo transfer (OR: 3.375, 95% CI: 1.556-7.321 p = 0.002), and the number of embryos transferred (OR: 2.653, 95% CI:1.226-5,743, p = 0.013) were the major factors contributing to the live birth rate after cleavage-stage frozen embryo transfer among young women. The cut-off point for infertility duration was 4.5 years, and the cut-off point for endometrial thickness was 0.89 cm. Infertility duration, endometrial thickness and number of embryos transferred might affect the live birth rate after frozen embryo transfer among young women. This result could help inform clinical decisions and counseling to increase the live birth rate after frozen embryo transfer among young women.

Outcomes of in vitro fertilization (IVF) treatment are traditionally reported as pregnancies per IVF cycle. However, a couple's primary concern is the chance of a live birth over an entire treatment course.We estimated cumulative live-birth rates among patients undergoing their first fresh-embryo, nondonor IVF cycle between 2000 and 2005 at one large center. Couples were followed until either discontinuation of treatment or delivery of a live-born infant. Analyses were stratified according to maternal age and performed with the use of both optimistic and conservative methods. Optimistic methods assumed that patients who did not return for subsequent IVF cycles would have the same chance of a pregnancy resulting in a live birth as patients who continued treatment; conservative methods assumed no live births among patients who did not return.Among 6164 patients undergoing 14,248 cycles, the cumulative live-birth rate after 6 cycles was 72% (95% confidence interval [CI], 70 to 74) with the optimistic analysis and 51% (95% CI, 49 to 52) with the conservative analysis. Among patients who were younger than 35 years of age, the corresponding rates after six cycles were 86% (95% CI, 83 to 88) and 65% (95% CI, 64 to 67). Among patients who were 40 years of age or older, the corresponding rates were 42% (95% CI, 37 to 47) and 23% (95% CI, 21 to 25). The cumulative live-birth rate decreased with increasing age, and the age-stratified curves (< 35 vs. > or = 40 years) were significantly different from one another (P<0.001).Our results indicate that IVF may largely overcome infertility in younger women, but it does not reverse the age-dependent decline in fertility.
