Active clinical trials for "Infertility"

To examine the chromosomal number content in the blastomeres of embryos achieved from fertilization of immature oocytes at MI stage recruited following COH for IVF. comparison of the genetic number content of embryos and their quality in terms of cleavage rate and morphological score reached after fertilization of immature oocytes at MI stage whether arrested at the MI stage or extruded the polar body, after in vitro maturation for a variable length of time.

At the Leuven University Fertility Centre (LUFC) of the Department of Obstetrics and Gynecology of the University Hospitals Leuven, Belgium, a retrospective epidemiological prevalence study based on an electronic search of patient files was performed to determine the prevalence of histologically proven endometriosis in a subset of infertile women with a regular cycle (variation 21 - 35 days), a partner with normal sperm and no previous surgical diagnosis of endometriosis.

The purpose of this study is to determine whether inherited thrombophilias (tendency toward blood clotting) increase the risk of failure of the embryo to implant in IVF. The specific condition to be studied is the presence or absence of the Leiden mutation of the Factor V gene.

Although Caesarean section (CS) is often a necessary surgical intervention, it may also be associated with an increased risk of short- and long-term sequelae. It was thought that CS may increase the risk of female subfertility or even infertility. In assisted reproductive technology (ART) cycles, the process of implantation is believed to be the most important factor in determining pregnancy outcome. In view of conflicting results on the influence of a previous CS on outcomes of ART, this study will be conducted to investigate the impact of the mode of previous delivery on ICSI outcomes.

The primary outcome of the study is to determine if a difference in terms of pregnancy rate exists between direct and afterload embryo transfer (ET) techniques. The secondary end points include the evaluation of the difficult transfer rates.

Three D power Doppler US was done for every woman at the day after HCG administration. Ovum pick up was done after 35 hours following HCG administration. The luteal phase was supported by progesterone 300 mg per day (progest, micronized progesterone 100mg, Technopharma, Egypt, for pharco pharmaceuticals, Amriya- Alexandria). Five days following ovum pick up, the embryos were transferred at the blastocyst stage.

Oocyte maturation requires a lot of energy, which is provided by the mitochondria via the synthesis of ATP. The majority of patients with advanced maternal age (AMA) have poor egg quality. One of the reasons depends on oxidative phosphorylation of Pyruvate to undergo maturation; on the contrary, the cells of the cumulus (CC) show great activity glycolytic so that these cells are able to provide ATP(adenosine triphosphate and energy substrates to the oocyte. The goal of this work is to analyze the mitochondrial function and energy production in oocyte donors compared with a group of women of advanced maternal age subject to a same ovarian stimulation Protocol

The investigators evaluate the feedback of using swim down semen processing method during preparation for ICSI and compare the results of pregnancy and embryos quality with the cases used density gradient method for their semen processing.

To determine whether there is higher incidence of skewed X chromosome inactivation(SXCI) in the recurrent miscarriage(RM) population compared with normal population, and verify the existing hypothesis of the possible genetic mechanisms underlying the association between SXCI and RM.

300 women with unexplained infertility who are already decided to be treated with ICSI will be recruited from Cairo university hospitals and Dar Al-Teb subfertility centre. On the second day of menstruation serum FSH, LH, Prolactin and Oestradiol will be assessed and the antral follicular count (AFC) will be assessed using a vaginal ultrasound scan. AFC will be defined as the number of follicles measuring 3-10mm. All patients will have standard pituitary down-regulation followed by (Human menopausal gonadotrophin (HMG) stimulation until the day of (Human chorionic gonadotrophin (HCG) administration. On the day of HCG administration, ovarian ultrasound scan will be performed using a transvaginal probe and the Preovulatory follicle count (PC) will be assessed, (PFC) is defined as number of follicles measuring≥16mm. FORT will be calculated as: (PFC) * 100/AFC.
