Abstract

The failure rate of in vitro fertilization (IVF) is around 75% per cycle. These unsuccessful attempts can provoke acute clinical depression and other problems. Although practitioners often recommend cognitive reappraisal, rather than avoidance, to cope with these difficulties, previous research has not established the psychosocial determinants of adaptive coping strategies. Arguably, resilience could encourage cognitive reappraisal, because resilient individuals feel confident they can overcome their emotions, whereas marital quality could prevent avoidance, because individuals feel secure enough to reflect upon their distress. Consequently, resilience and marital quality could facilitate recovery over time. To explore these possibilities, 184 women, all of whom had unsuccessfully completed IVF treatment, completed a questionnaire that gauged their levels of self-reported depression since their last IVF attempt as well as resilience and marital quality. Immediately after the unsuccessful attempt, resilience was inversely, whereas marital quality was positively, related to depression. However, within this cross-sectional sample after greater time had elapsed, marital quality became increasingly beneficial and was negatively associated with depression. These findings imply that resilience can curb the initial distress; in contrast, marital quality may enable individuals to reflect upon their trauma, initially amplifying distress but eventually facilitating recovery. Future research would benefit from longitudinal studies, illustrating whether resilience and marital quality at one time predict changes in distress at subsequent times.  相似文献

It is a known fact that abnormal seminal liquid specimens contain abnormal amounts of oxygen free radicals and reactive oxygen species (ROS), and that the use of antioxidant molecules both in vivo and in vitro leads to improvement of semen quality in terms of motility, reduction in DNA damage, with obvious consequences on the fertilization potential. Myo-inositol has been observed to have anti-oxidant properties and be present in much greater concentrations specifically in seminal liquid than in the blood. Moreover, there seems to be a direct relationship between myo-inositol and mitochondrial membrane potential (MMP) and sperm motility. Studies performed in vivo have demonstrated that a dietary supplementation with myo-inositol in men undergoing assisted reproduction techniques may improve sperm quality and motility in oligoasthenospermia (OAT) patients. In the following study we utilized myo-inositol in vitro to verify its effect on semen quality in both normal and OAT patients undergoing in vitro fertilization (IVF) with respect to standard sperm medium. In vitro incubation of seminal liquid carried out using myo-inositol (Andrositol-Lab, Lo.Li. Pharma-Roma, Italy) at a concentration of 15?μl/ml improved progressive motility in both normospermia and OAT subjects. In our opinion, myo-inositol may prove to be a useful strategy to improve sperm preparation for clinical use in IVF.  相似文献

Fifty patients of an in vitro fertilization (IVF) program were compared to 25 individuals undergoing fertility investigation other than IVF. Each subject was given the California Psychological Inventory (CPI) and a social history interview during which behavioral signs of anxiety were noted. The CPI profile indicated the IVF subjects to be higher on characteristics of ambitiousness, creactivity, and independence. No major differences were noted on the interview questions and behavioral ratings. Both groups may view IVF as a possible treatment for their infertility; however, the IVF patients have certain personality characteristics which make them more likely to actually become involved.  相似文献

Ultrasonic studies for the detection of a cumulus oophorus were carried out in 57 women taking part in an in vitro fertilization (IVF) program. When intrafollicular echoes were dissociated, clearly prominent from the follicular wall, they were considered to be a sure cumulus mass, and when they were only slightly prominent, they were suspected to be a nondissociated cumulus. All patients had at least one ultrasonically visible cumulus. A cumulus was seen in 50% of the follicles and 70% of them were dissociated. Cumuluses were also seen in follicles <18 mm in diameter but a significantly higher number of them were not clearly dissociated. The number of observed dissociated cumuluses correlated significantly with the number of recovered mature oocytes. However, in 18 patients there were more mature oocytes retrieved than cumuluses identified by ultrasound. When a cumulus mass is seen, it can be taken as evidence of a sign of maturity of that particular follicle and oocyte. However, mature oocytes are also found where no cumulus was seen by ultrasound. Lack of visible cumulus has little significance in predicting the maturity of the oocyte.  相似文献

Approximately 80% of the patients in a program of in vitro fertilization (IVF) will fertilize an oocyte. The purpose of this study was to determine which parameters of the semen analysis influence fertilization in vitro. Of 120 patients participating in an in vitro fertilization program, 98 achieved fertilization of at least one mature oocyte and 22 did not. Ovulation induction was standardized and patients whose sperm was exposed to at least one mature oocyte (by light microscopy) were included in the study. Semen washing was accomplished using a swim-up technique. Semen parameters were assessed both before (raw) and after washing. Following insemination with 100,000 motile sperm, fertilization was determined by the presence of pronuclei or cleavage. Mean sperm count and motility were higher in patients who fertilized. However, morphology was similar. Fertilization was more likely to occur with a raw density>104 million/ml and a motility>64%, as well as with a density>18 million/ml and a motilkity>86% following washing. Furthermore, washing lowered sperm counts by 75% and increased motility by 25% but had no effect on morphology. This study demonstrates that sperm count and motility, but not morphology, influence fertilization in a program of in vitro fertilization and that patients with higher counts and motility have and greater probability of fertilization.Presented at the Third Annual Congress of Andrology, April 27–May 2, 1985, Boston, Massachusetts.  相似文献

OBJECTIVE: To report acute abdomen in a young woman with infertility due to small asymptomatic bilateral hydrosalpinges who was on the 12th day of an IVF cycle. DESIGN: Case report. SETTING: Private IVF clinic. PATIENT(S): A 35-year-old woman with asymptomatic bilateral hydrosalpinges. INTERVENTION(S): Abdominal laparoscopy. MAIN OUTCOME MEASURE(S): Pus and a ruptured left pyosalpinx. RESULTS: The patient suddenly developed acute abdomen while lifting a disabled person at a nursing home where she worked as a nurse. About 200 mL of pus was aspirated, and the patient had a ruptured left pyosalpinx. Bilateral salpingectomy was done by laparoscopy; the patient's postoperative recovery was uneventful. CONCLUSION: We report a rare case of acute abdomen due to peritonitis after a ruptured pyosalpinx in an IVF patient who lifted a disabled person.  相似文献

OBJECTIVE: To study the endometrial expression of three integrins (alpha v beta 3, alpha 4 beta 1, and alpha 1 beta 1) in women undergoing IVF-intracytoplasmic sperm injection (ICSI) treatment and assess whether they could be used to predict subsequent treatment success.Prospective observational study.Healthy volunteers in a large teaching hospital. PATIENT(S): Sixty-six patients attending for IVF-ICSI treatment. INTERVENTION(S): Timed endometrial biopsies were taken, during the implantation window at LH + 7-9 days, from women before IVF-ICSI treatment. MAIN OUTCOME MEASURE(S): Histological dating of endometrium and immunohistochemical staining intensity of alpha 4 beta 1, alpha v beta 3, and alpha 1 beta 1 integrins. The integrin levels were correlated with subsequent success rates. RESULT(S): There was a statistically significantly greater expression of alpha v beta 3 in the luminal epithelium of those patients who had successful treatment. However, treatment was successful in some patients with negative expression. CONCLUSION(S): Integrins are important markers of endometrial receptivity. There is an association between an in-phase endometrial biopsy, with positive luminal alpha v beta 3 integrin expression, and subsequent treatment success. However, the clinical value of assessing the endometrium before treatment has drawbacks, and further work needs to be done before this can be considered a clinically useful test.  相似文献

Endocrine evaluation as a prerequisite for every patient undergoing routine in-vitro fertilization (IVF) and embryo transfer for tubal or male factor infertility is still a matter of debate. The aim of this study was to determine if a full endocrine work-up, including the measurement of androgens, gonadotropins, prolactin and TSH, is conclusive for the subsequent success in IVF/ET. 71 infertile women without known endocrinopathies (e.g., polycystic ovarian disease), who were scheduled to enter the IVF/ET program were studied under strictly standardized conditions during the follicular phase of a natural cycle. Fasting serum concentrations of follicle stimulating hormone, luteinizing hormone, oestradiol, progesterone, prolactin, testosterone (T), dehydroepiandrosterone, 17-OH-progesterone, androstenedione and thyroid stimulating hormone (TSH) were measured using commercially available radioimmunoassays. Ovarian stimulation was performed by a long gonadotrophin-releasing hormone agonist/human menopausal gonadotrophin protocol. The overall clinical pregnancy rate was 15.5% in the first started IVF cycle. While patients who conceived in the first treatment cycle had significantly lower T levels (368±49 pg/ml) than those who did not (518±27 pg/ml, p=0.042, Kruskal & Wallis H-test), but the percentage of women with elevated T concentrations was not different. Similarly, TSH concentrations were significantly higher in women with a clinical pregnancy (1.9±0.2 mU/ml) than in non-pregnant women (1.4±0.3 mU/ml, p=0.046), but levels were still within the normal range. There were no further significant differences in hormone levels between pregnant and non-pregnant patients. These results do not suggest the measurement of a full hormonal profile in all infertile women before IVF/ET in non-endocrine infertility, taking into account the low likelihood to identify endocrinological disturbances, the considerable cost of endocrine testing and the paucity of therapeutic consequences Received: 9 April 2000 / Accepted: 25 July 2000  相似文献

PURPOSE: To evaluate the role of 3-D US measurement of the endometrium during early IVF-pregnancy and before the appearance of gestational sac in the prediction of pregnancies outcome. METHODS: 60 pregnant women following IVF treatment were included in the study. The women underwent transvaginal 3D US measurements of endometrial volume and thickness on day 15-17 post ET. Patients were followed and classified according to pregnancy outcome into 2 further groups. The group with early pregnancy loss and the group with ongoing pregnancy. RESULTS: While no differences were observed between those who miscarried and those who did not in gestational age, endometrial thickness or volume, spontaneous early pregnancy loss was significantly higher in patients with endometrial volume <2 mL as compared to those with endometrial volume >2 mL. CONCLUSIONS: 3-D US measurement of endometrial volume of less than 2 mL during early IVF pregnancy and prior to the appearance of gestational sac is a powerful predictor of pregnancy loss.  相似文献

Purpose

The aim of this study is to investigate the effect of female BMI and metabolic dysfunction on blastocyst formation rate.

Methods

This was a retrospective cohort study that was performed in an academic center for reproductive medicine. Patients who were normal weight, overweight with metabolic dysfunction, or obese who had ≥6 oocytes retrieved in a fresh IVF cycle were included in the study. The blastocyst formation rate was calculated from the number of ≥5 cell embryos on day 3 observed in culture until day 5 or day 6. Only good quality blastocysts were included in the calculation as defined by a morphologic grade of 3BB or better.

Results

The blastocyst formation rate was significantly better in the normal-weight controls versus overweight/obese patients (57.2 versus 43.6 %, p < 0.007). There was no difference in blastocyst formation between the patients with a BMI 25–29.9 kg/m2 with metabolic dysfunction and those with a BMI ≥30 kg/m2.

Conclusion

The maternal metabolic environment has a significant impact on embryo quality as measured by blastocyst formation. A decreased blastocyst formation rate is likely a significant contributor to poorer reproductive outcomes in overweight and obese women with infertility.  相似文献

OBJECTIVE: To compare the agonist flare-up and antagonist protocols in the management of poor responders to the standard long down-regulation protocol. DESIGN: Retrospective comparative study. SETTING: Assisted conception center. PATIENT(S): One hundred thirty-four patients undergoing IVF/ intracytoplasmic sperm injection (ICSI) treatment, who responded poorly to the standard long down-regulation protocol in their first treatment cycle. In the second cycle, 77 received short flare-up agonist and 57 received antagonist protocol. We analyzed the outcome of the second cycle. INTERVENTION(S): Peak serum E(2) was assayed on the day of hCG administration. MAIN OUTCOME MEASURE(S): Cycle cancellation rate due to poor ovarian response. RESULT(S): There was no cycle cancellation in the flare-up protocol and 7% cancellation rate in the antagonist protocol due to lack of response. A significantly higher number of patients had embryo transfer in the flare-up protocol. There was no difference in pregnancy rate (PR) between the two groups. CONCLUSION(S): Both the flare-up and the antagonist protocols significantly improved the ovarian response of known poor responders. However, a significantly higher cycle cancellation rate and less patients having embryo transfer in the antagonist group tips the balance in favor of the flare-up protocol.  相似文献

World collaborative report on in vitro fertilization, 2000   总被引:4,自引:0,他引:4  
The International Committee for Monitoring Assisted Reproductive Technology's 7th World Report for the year 2000 analyzes wide variations in live and multiple birth rates from 49 countries and six regions by type of assisted reproductive technology, age, number of embryos transferred, and multiple births. More than 460,157 procedures resulted in delivery rate per aspiration for conventional in vitro fertilization (IVF) of 18.6%; for intracytoplasmic sperm injection (ICSI), 20.4%; for egg donation, 32.3% per transfer; and for frozen ET, 12.0% per transfer. Conventional IVF and ICSI twin rates were 26.9% and 26.2%, respectively, and triplet rates were 2.8% and 2.9%, respectively, for an estimated total of approximately 197,000 to 220,000 babies worldwide.  相似文献

The glycosaminoglycans (GAGs) chondroitin sulfate (CS) and heparan sulfate (HS) were assayed in fluid from 178 individual follicles obtained from women after human menopausal gonadotropin ovulation induction for subsequent in vitro fertilization. CS and HS concentrations ranged from 0 to 3.9 and 0 to 18.6 mg/ml, respectively. The percentage of oocytes fertilized was significantly higher when CS concentrations ranged from 0.3 to 0.8 mg/ml (P less than 0.03). As HS levels increased, maturation scores by visual assessment of the egg-corona-cumulus cell complexes increased (P less than 0.05), but the percentage of oocytes fertilized was not affected. Cleavage rates of developing embryos were not related to the concentrations of GAGs.  相似文献
