Filter by:The objective of this study was to evaluate the outcome of follicle stimulating hormone (FSH) co-administration with human chorionic gonadotrophins trigger for women with unexplained infertility (UEI) and assigned for letrozole (LTZ) stimulated intrauterine insemination (IUI) cycles .
Women between 18-39 years old who had been infertile (primary or secondary) for at least 1 year were recruited. In a parallel assignment eligible participants were randomized to receive either a single, site-specific endometrial injury guided by hysteroscopy (Study group) or no intervention (Control group). Natural cycle folliculometry + timed sexual intercourse were offered for all participants for the ongoing and the immediate 2 concecutive cycles. Clinical pregnancy rates were the primary outcome and miscarriage rates were the secondary outcome measures.
Infertility affects one in six couples. In a quarter of them, routine tests of semen quality, ovulation or tubal patency fail to reveal any abnormalities and the cause of infertility is unexplained. Acupuncture is being increasingly used by couples with all types of infertility and initial trials have suggested that it could be potentially beneficial in some cases. A number of systematic reviews of acupuncture in IVF have shown conflicting results, but there is no evidence to inform best practice in unexplained infertility. In addition, as an intervention, acupuncture is not cost neutral as it involves multiple visits for treatment sessions delivered by a skilled practitioner. Thus, while acupuncture could have the potential to increase live birth rates in women with unexplained infertility, the clinical and cost effectiveness of acupuncture needs to be confirmed in the context of a large randomized controlled trial.
The purpose of this study is to determine whether preovulatory uterine flushing with physiological saline is effective in the treatment of unexplained infertility.
The aim of the current study is to evaluate to effectiveness of sperm selection by using fertile chip in unexplained infertile couples on intracytoplasmic sperm injection (ICSI) cycles.
The study included 154 infertile women Patients received 100 mg of oral clomiphene citrate for five days starting on day 3 of the menstrual cycle, followed by daily injection of 150 IU of hMG and when more than two dominant follicles reached a diameter of 17 mm 5,000 IU of hCG was injected intramuscularly. Patients were randomly allocated into two equal groups: Group C received IUI without ESI and Group S had ESI using No.8 neonatal feeding tube and after 24 to 36 hours, IUI was performed. Successful pregnancy was con-firmed by ultrasound and patients had failed trial underwent another trial of IUI for a maximum of three trials.
The overall objective of this study is to determine whether serum BPA and/or phthalate concentrations differ in fertile versus infertile men and women in Saskatchewan. The investigators will test the following hypothesis: 1. Serum BPA and/or phthalate concentrations will be greater in women with unexplained infertility or PCOS compared to a control group 2. Serum BPA and/or phthalate concentrations will be greater in men with male factor infertility compared to a control group
Recent research has revealed that subtle abnormalities can be found in sperm samples that seem to be normal with conventional analysis techniques. The DNA in the sperm heads is sometimes fragmented and this may be the reason why couples with a diagnosis of unexplained infertility do not achieve pregnancy. We are planning a study to examine the incidence of DNA fragmentation in the sperm of couples with previously unexplained infertility. In a first treatment cycle with intra-uterine insemination the percentage of DNA fragmentation in sperm will be measured. Afterwards the results of the patients who are pregnant will be compared with those of the not pregnant ones. We expect to find differences between both groups. 100 patients will be included in the study.
Research question: Population: women with unexplained infertility. Intervention: endometrial scratching by pipelle for women with unexplained infertility. Comparison: to compare with non endometrial scratching for women with unexplained infertility. Outcome: the biochemical pregnancy rate. Research hypothesis: Null hypothesis: there is no difference in the rate of pregnancy between scratching and non endometrial scratching in women with unexplained infertility. Alternative hypothesis: there is difference in the rate of pregnancy between scratching and non endometrial scratching in women with unexplained infertility.
Sperms are prepared by sperm washing techniques before used in assisted reproductive technologies. Most commonly used sperm preparation methods are the swim up and the density gradient. Recent studies shows that the DNA integrity status of the spermatozoa is related to the success in assisted reproduction techniques. Sperm preparation methods may theoretically cause damage to sperm DNA. Therefore it is important to select the optimum method of sperm preparation causing least sperm DNA damage. Aim of our study is to investigate and compare the effect two different sperm preparation techniques on DNA fragmentation.
