Active clinical trials for "Infertility"

Background : Up to 15 percent of couples are infertile. In up to half of these couples, male infertility plays a role. Male infertility is due to low sperm production, abnormal sperm function or blockages that prevent the delivery of sperm. Illnesses, injuries, chronic health problems, lifestyle choices and other factors can play a role in causing male infertility. Methodology : It is an interventional trial that involved 45 participants with infertility (Oligospermia, Hypospermia, Asthenozoospermia and Necrozoospermia). All the participants underwent a semen analysis for his semen count, volume and motility for a sample taken by masturbation. Then I gave each one of the participants a small device. This device gives an electrical shock up to 5 milliamps. I told each one independently to use this device properly on his testis every day and come for follow up checking every month. After the fourth months, I made the final checkup for everyone and records my data and make a comparison between (before and after) semen analysis.

At present, the evaluation criterion of endometrial receptivity is controversial. The development of a molecular diagnostic tool, the endometrial receptivity array (ERA) for diagnosis of endometrial receptivity . But use of this test in patients with RIF has shown that the window of implantation (WOI) is displaced in only a quarter of these patients and use of a personalized embryo transfer (pET) on the day designated by ERA improves reproductive performance with higher cost .what is known to the others'population? The morphological changes observed on histology for each specific day after ovulation were described by Noyes and his colleagues in 1950 . An endometrial biopsy that shows a difference of more than 2 days between the histologic dating and actual day after ovulation is considered to be ''out of phase''. But such pET studies according to the Noyes criterion are lacking . The aim of this study is to explore the Personal frozen-thawed embryo transfer in unexplained RIF patients according to the blinded histological dating of endometrial biopsies .

Background: Despite the high success rate of ICSI, total fertilization failure still occurs in 1-3% of all ICSI cycles and can recur in subsequent cycles, even when a sufficient number of oocytes and motile spermatozoa are available. Several reports show that the majority of couples suffering from ICSI failure benefit from the application of ICSI combined with assisted oocyte activation. A variety of artificial activating methods is used in human assisted reproduction treatment, including physical, mechanical or chemical stimuli, which provoke one or more calcium rises in the oocyte cytoplasm. Study Design: Randomized controlled trial. Setting: A university fertility center. Methods: 150 infertile patients who underwent ICSI and all had history of recurrent fertilization failure. The patients were randomly allocated into 2 equal groups. Group1=75 patients who underwent ICSI without oocyte activation. Group2 patients =75 and underwent ICSI Patient underwent ICSI with oocyte activation. Reproductive outcomes were compared between both groups. Results: there were significant differences between groups regarding number of oocytes retrieved, number of mature oocyte, fertilization rate and pregnancy rate. Conclusion: Assisted oocyte activation with calcium ionophore results in significant improvement in the fertilization, cleavage and pregnancy rates after ICSI.

Comparing two ovarian induction protocols in poor responders in IVF/ICSI cycles

The aim of this study is to compare different FSH/LH ratios in controlled ovarian stimulation

The study will focus on important aspects related to follicle recruitment using exogenous gonadotropins in patients with polycystic ovaries: Early follicle recruitment in patients with polycystic ovaries using corifollitropin alfa: does administration of this drug result in earlier and higher FSH (follicle stimulating hormone) concentrations above the threshold for follicle recruitment in an IVM (in vitro maturation) cycle preceded by oral contraceptive suppression, in comparison to normal daily administration of rFSH (recombinant follicle stimulating hormone, Puregon)?; The maturation rate of the obtained oocyte-cumulus complexes in standard IVM media registered for clinical use: does stimulation with corifollitropin alfa versus recombinant FSH have an impact on the maturation rate and developmental capacity of the oocytes ?

In this prospective randomized trial, the parameters of the frozen-thawed embryo transfer (FET) cycles were analyzed. This study was undertaken in the Department of Assisted Reproductive Technologies and Reproductive Genetics Center at Istanbul Memorial Hospital with approval of the local ethics committee. The aim of this prospective randomized clinical trial was to compare two methods of endometrial preparation for FET, oral estradiol and estradiol transdermal patch.

Infertility is defined as a couple's inability to become pregnant after one year of unprotected intercourse in women 35 years old and younger, and for six months in women over age 35 years. In any given year, about 15 percent of couples in North America and Europe who are trying to conceive are infertile

This study is a prospective randomized trial with 242 IUI cycles. Patients are randomized in two groups including 121 cycles in each group. A total of 255 cycles in 167 patients are finally recruited. In the first group, the patients will be treated with triptorelin (Gonapeptyl®) in their luteal phase. As for the other group, the patients will undergo the luteal phase without any supportive medication. This study is going to clarify the role of the gonadotropin agonist (triptorelin acetate, Gonapeptyl®) as a luteal phase supporter. The benefit of the treatment is measured by the numbers in the live birth and clinical pregnancy rates.
