Infertility Clinical Trials

With advanced age, ovarian reserve decreases, follicular cohort becomes heterogeneous under the influence of higher FSH rise in late luteal phase. It has been shown that estrogens (E2) taken in the late luteal phase homogenized follicular cohort by inhibiting inter cycle FSH peak ,and that this inhibition is immediately reversible ...

The success rate of assisted reproductive technology (ART) has dramatically increased due to the improvements in embryo culture, laboratory conditions, and optimization of different ovarian stimulation protocols. Recent data shows that if hCG is not administered for oocyte maturation, severe OHSS is very rare. However, with gonadotropin releasing hormone (GnRH) ...

Literature suggests that GnRH antagonists are comparatively more often used in cycles which have an unfavorable prior prognosis, and this protocol is an ideal one for poor responder patients. Up to now, however not enough prospectives have been published to prove any beneficial effect of antagonists on the first cycle ...

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive age, with an incidence of 5 -10% . Classically clomiphene citrate (CC) is the first approach to induce ovulation in patients with PCOS. Although 70-80% of PCOS women can ovulate by the treatment with CC, only 40%of the ...

All the patients who diagnose as poor ovarian responders (POR) based on the Bologna criteria are eligible for participation in this study. In order to define the poor response in IVF, at least two of the following three features must be present: (i) advanced maternal age or any other risk ...

Studies in primates showed that treatment with testosterone increased the number of growing follicles, lead to proliferation of granulosa and theca cells, while finally reduced the apoptosis of granulosa cells (Vendola et al., 1999; Weil et al., 1999). These studies further suggest that androgens may have a specific action in ...

Study Objective An intensive lifestyle modification intervention (which includes caloric restriction, use of an over-the-counter weight loss medication, and moderate physical activity with tracking) designed to promote a weight loss of approximately 7% of initial body weight is more likely to achieve a good perinatal outcome (i.e. a healthy term ...

The proposal of this study approved by our institutional review boards and institution's ethical committee, and all participants will sign a written consent before enter to study. All patients will be randomly divided into two groups of thawed cleavage embryo transfers and transfers of blastocysts from thawed cleavage embryos. Embryos ...

The potential therapeutic effect of diagnostic tubal patency testing has been debated for over 40 years. Tubal flushing might involve water- or oil-soluble media. Current practice usually involves water-soluble media when tubal flushing is performed at laparoscopy. A systematic review showed a significant increase in pregnancy rates with tubal flushing ...

Unexplained infertility is a common diagnosis encountered in the subfertility clinic; about 15-30% of infertile couples will be diagnosed as having unexplained infertility. Couples are usually diagnosed as having unexplained infertility if the woman has ovulatory cycles, patent tubes and the spouse has a normal semen analysis according to the ...
