Filter by:Intra-uterine insemination (IUI), generally in combination with ovarian stimulation, is one of the most commonly used treatments for infertility. Accurate timing of insemination, in order to coincide with ovulation, has an important impact on the success rate. Optimal timing of insemination is achieved either by monitoring follicular growth through serial ultrasound measurements followed by the administration of human chorionic gonadotropin (hCG) or by the detection of urinary luteinizing hormone (LH). However in cycles where follicular growth is monitored there is a possibility of premature LH rise before the administration of hCG, which may affect the outcome of the treatment. The goal of the study is to determine if adding the testing of urine LH in conjunction with ultrasound monitoring leads to an increase in pregnancy rates in IUI cycles when compared to ultrasound monitoring alone.
The purpose of this study is to investigate the effect of G-CSF on endometrial thickness in women who have failed reaching minimal endometrial thickness by standard treatments, to assess how many reach embryo transfer and what implantation and pregnancy rates are in comparison to control patients. The study will be conducted in women undergoing transfer of previously cryopreserved embryos or undergoing transfer of embryos from donor eggs.
This study aims to assess the feasibility of a novel standard of care technique for intrauterine insemination (IUI) in HIV-discordant couples in the United States. This study will involve couples in which the male partner is HIV positive, but the female partner is negative. The investigators will institute a protocol similar to those used presently throughout Europe with good success. To date, no HIV seroconversions have occurred in over 4000 inseminations performed in HIV serodiscordant couples. All male subjects will be on stable HAART, and have undetectable serum viral loads prior to insemination. Semen samples will be subjected to a stringent sperm wash procedure and screened for HIV RNA. Female subjects will be followed post-insemination for seroconversion and pregnancy. Infants will be followed for seroconversion at birth through 4 months of age.
The objective of this study is to evaluate the effect of endometrial injury performed prior ovulation induction for assisted reproductive techniques main outcomes.
This prospective study evaluates the effect of DHEA supplementation on markers of ovarian reserve in women with diminished ovarian reserve.
This is a single center, prospective, observational study on the use of Gonal-f in controlled ovarian hyperstimulation (COH) in subjects undergoing ovulation induction/ intrauterine insemination (OI/IUI) therapy across Taiwan. It has been observed in the previous studies that COH with follicle stimulating hormone (FSH) is considered as one of the positive predictors of an ongoing pregnancy. Many studies in the past have tried to predict the FSH threshold, defined as the FSH dose on the day when a follicle is >10 mm in diameter, but no studies have been conducted to date to determine the predictive factors for a monofollicular development after COH in IUI cycles. Monofollicular growth contributes significantly to the reduction of multiple pregnancies and thus minimize the risks associated with such pregnancies. This study would provide preliminary data on the factors associated with a monofollicular development in Gonal-f treated cycles using a low dose step-up regimen.
Ovarian reserve is related to chronological age; 35 years of age is the accepted threshold for significant decline in assisted reproductive technologies (ART) success with scarce follicular recruitment and poor oocyte retrieval. New therapeutic schemes are sought to improve follicular response in ovarian ageing because of the increasing number of infertile women aged older than 35 years who are trying to get pregnant. The advent of gonadotropin releasing hormone analogue antagonist (GnRHant) offers new perspectives to address the issues related to advanced reproductive age since it prevents premature luteinizing hormone (LH) surges while not causing suppression in the early follicular phase. Gonadotropin releasing hormone analogue antagonists are administered in the latter stage of the ovarian stimulation to prevent LH surge by competitive blockade of gonadotropin releasing hormone (GnRH) receptors, thus producing a marked decrease in LH levels just when the interplay between follicle stimulating hormone (FSH) and LH becomes important to complete follicular development and oocyte competence. Some studies in the past have shown the potential of recombinant human LH (r-hLH) supplementation in women of advanced reproductive age to improve oocyte quality, but these studies are of small size and did not provide data on the physiological mechanism behind the benefit obtained. This randomized, comparative, parallel controlled Phase II study will be conducted in infertile female subjects aged 35-42 years undergoing in-vitro fertilization (IVF)/intra cytoplasmic sperm injection (ICSI), to investigate whether the addition of r-hLH (when the lead follicle is greater than [>] 14 millimeter [mm] in size), to the standard protocol with recombinant human FSH (r-hFSH) under GnRHant, improves the number and quality of oocytes retrieved, implantation rate, and pregnancy rate, while assessing the hormonal milieu in the ovarian follicular fluid. Comparison will be performed against ovarian stimulation without addition of r-hLH, that is (i.e.) with r-hFSH under GnRHant alone.
This is a multicentric, open, randomized, comparative trial aimed to assess the influence of recombinant luteinizing hormone (r-LH) supplementation during controlled ovarian stimulation (COS) in advanced reproductive age in terms of improved embryo competence which allows to transfer less embryos to avoid high grade multiple pregnancy without reducing the pregnancy rate.
Women undergoing in vitro fertilization (IVF) therapy, who are low responder and agree to enter the trial will be randomized to a study group, for whom embryo transfer will be done on the same day as oocyte aspiration and fertilization; and a control group for whom embryo transfer will be performed 48 to 72 hours later, as is the current accepted practice.
GnRH agonist administration in the luteal phase was reported to beneficially affect clinical outcome of ICSI-ET cycles. This randomized controlled trial evaluates the effect of a single dose GnRH agonist administered in the luteal phase on the outcome of ICSI - ET cycles stimulated with the fixed GnRH antagonist protocol. Women undergoing embryo transfer following controlled ovarian hyperstimulation with a fixed GnRH antagonist protocol were included. In addition to routine luteal phase support with progesterone women were randomized to receive a single dose of GnRH agonist or placebo on the sixth day after ICSI.Ongoing pregnancy rate was the primary outcome measure.
