子宫内膜异位症(endometriosis,简称内异症)与不孕密切相关,内异症患者不孕症发生率高达40%~50%。其可以通过多种机制协同影响而导致不孕症:①盆腔解剖结构改变和输卵管结构或功能异常,干扰配子或胚胎的运输;②异常子宫收缩,影响精子运输和胚胎着床。 相似文献

Influence of embryo transfer depth on in vitro fertilization and embryo transfer outcomes 总被引:23,自引:0,他引:23
OBJECTIVE: To investigate the influence of transfer distance from the fundus (TDF) on clinical pregnancy rate (PR) and ectopic pregnancy rate. DESIGN: Retrospective cohort. Between January 2000 and December 2001, 699 ultrasound (US)-guided embryo transfers were conducted. Mock transfer was performed to measure uterine cavity depth 1 month before treatment. Cavity depth was measured by abdominal US before the transfer, from the vaginal stripe to the fundus. Transfers were performed with a Wallace embryo transfer catheter (Cooper Surgical, Shelton, CT) using US and physician's judgment of cavity depth. Transfer distance from the fundus was calculated by subtracting the depth of catheter insertion from the cavity depth, as determined by US or by mock transfer. Statistical analyses were performed by building a multivariable logistic regression model to calculate odds ratios and 95% confidence intervals (CI). SETTING: Women aged 23 to 43 years who are in a university-affiliated, community-based IVF program in Springfield, Massachusetts. PATIENT(S): All patients enrolled in IVF program undergoing embryo transfer. INTERVENTION(S): No patient received any additional procedure or intervention. All of the measurements obtained with the embryo catheter and the transvaginal ultrasound were part of the program's protocol for the embryo transfer. MAIN OUTCOME MEASURE(S): Odds ratio examining relationship between embryo transfer depth and PR.Clinical, implantation, and ectopic PR were 37%, 20%, and 2.1%. Cavity depth by US differed from cavity depth by mock by at least 10 mm in >30% of cases. The TDF by US was highly predictive of PR; TDF by mock was not predictive of PR. Increasing the TDF by US resulted in significantly increased PR as well as lower ectopic rates. Using regression analysis, the odds ratio for TDF by US was 1.11 (95% CI: 1.07-1.14). This suggests that for every additional millimeter embryos are deposited away from the fundus, the odds of clinical pregnancy increased by 11%. CONCLUSION(S): After controlling for potential confounders, the clinical PR is significantly influenced by the transfer distance from the fundus. Cavity depth by US is clinically useful to determine the depth beyond which catheter insertion should not occur. 相似文献

In vitro fertilization is one of the newest approaches to infertility. Opportunities for nurses in IVF involve teaching couples about physiology, providing technical assistance and care, and counseling about the medical and emotional aspects of the program. Many times the nurse serves as the primary support person for couples and as their advocate with other team members. 相似文献

Hormonal profiles and embryo quality in women with severe endometriosis treated by in vitro fertilization and embryo transfer 总被引:2,自引:0,他引:2
A study was undertaken comparing the outcomes of 30 women with infertility due to untreated severe (grade IV) pelvic endometriosis with a comparable series of 28 women whose infertility was caused solely by irreversible tubal disease. There were no significant differences in either the follicular phase or luteal phase hormonal profiles of estradiol and progesterone, but there was a significantly reduced pregnancy rate in those women with severe endometriosis. In part, this was due to the recovery of fewer oocytes from the endometriosis patients (P less than 0.001) despite the fact that the peak estradiol levels and ovarian accessibility were similar in the two groups. However, there were no significant differences in the proportion of oocytes that fertilized or the number that demonstrated normal embryo growth and high-grade embryo quality. There also appears to be an implantation inhibitory factor in patients with severe endometriosis as the pregnancy rate/embryo transferred and number of gestational sacs identified/embryo transferred were significantly reduced (P less than 0.05). 相似文献

OBJECTIVE: Economic analyses in reproductive medicine often fail to take into account the chances of treatment-independent conception. We compared the cost-effectiveness of several realistic strategies involving IVF using no treatment as the reference strategy. DESIGN: A decision tree was constructed for a subfertile couple in which the clinician had to decide whether to offer treatment with IVF. No treatment at all was used as the reference strategy. SETTING: An analytic decision-making framework. PATIENT(s): Hypothetical subfertile couples. INTERVENTION(s): Two potential treatment approaches: three IVF cycles performed as soon as possible, or no treatment performed initially and then three or four IVF cycles performed if a pregnancy resulting in a live birth does not occur naturally after 212 years. MAIN OUTCOME MEASURE(s): The cost of establishing one pregnancy that results in a live birth. RESULT(s): The cost-effectiveness of IVF depended not only on the costs and expected success rates of IVF itself but also on the couple-specific chances of treatment-independent conception. Consequently, the cost-effectiveness of IVF is strongly dependent on the age of the female partner. This finding corresponds with everyday clinical experience. CONCLUSION(s): Economic analyses in reproductive medicine should take into account the option of providing no treatment. 相似文献

The expression of mitochondrial genes in granulosa cells was quantitated by real-time polymerase chain reaction. The expression ratio of mitochondrial genes in granulosa cells of patients with severe endometriosis showed no statistically significant difference compared with cases of tubal infertility without endometriosis. 相似文献

Summary We reported on the first pregnancy achieved in the Erlangen IVF program after cryopreservation and embryo transfer. After hMG stimulation in the first treatment cycle, nine oocytes were retrieved by laparoscopy from a 31-year-old woman and three embryos transferred. Fived other oocytes were fertilized and developed to four- to eight-cell embryos, which were subsequently cryopreserved. Transfer of these embryos two cycles later resulted in a singleton pregnancy and the birth of a healthy girl. 相似文献
