Active clinical trials for "Infertility"

The purpose of the study to evaluate effect of nitroglycerin trans-dermal patches on uterine and sub-endometrial blood flow in women with unexplained infertility.

Increased sperm DNA Fragmentation Index implies decreased male fertility in vivo and in vitro. There is need for developing new strategies for improvement of male fertility. The study aims to investigate whether high sperm DNA Integration Index can be treated by use of antioxidants.

The Researchers hope to learn if by using lavender aromatherapy during an intrauterine insemination patients have decreased anxiety and pain at the time of the procedure.

the aim of the study is to compare between the step-up and conventional protocols in ovulation induction in infertile women with PCOS

The study compares in a randomized controlled way two stimulation methods. One of these stimulation methods implements a new insight in ovarian follicular growth. If this novel method of stimulation proves to be as efficient as the classical stimulation protocols, there might be a dramatic reduction of the costs of the medical therapy in IVF, thus reducing also the overall IVf costs significantly.

Pregnancy rates fall dramatically in women after 35 years undergoing to IVF or ICSI. While ovarian aging obviously plays the major role in this phenomenon, over suppression of endogenous LH concentrations with GnRH agonists or antagonists-an integral part of standard IVF/ ICSI protocols-may also play a pivotal role. Assisted reproduction technology protocols using GnRH agonists have been considered as the standard protocol during the last two decades, but the use of GnRH antagonists offers the opportunity to control the endogenous LH surge in a rapid and more convenient way. LH plays a key role in the intermediate-late phases of folliculogenesis. The presence of receptors for LH in cumulus granulosa cells and its correlation with oocyte maturation has been demonstrated. Although ovarian stimulation is efficiently achieved in most cases by the administration of exogenous FSH alone, specific subgroups of women may benefit from LH activity supplementation during ovarian stimulation. Some authors have found improved outcome with LH activity supplementation in advanced reproductive age women. LH has a number of roles in follicular development, induction of ovulation, completion of meiosis I, early luteinization and the production of progesterone. The efficacy of recombinant human follicle-stimulating hormone (r-hFSH) for ovarian stimulation is well established however, the role of supplementary recombinant human luteinizing hormone (r-hLH) is less clear. Aim of the present study is to evaluate If adding rLH in the late phase of stimulation can benefit in some patient awith repeated implantation failure.

varicoclelectomy is done for subfertiltiy and varicocele induced orchialgia. The effect of varicocelectomy on semen analysis is controversial. Many articles report favorable outcomes and others do not. Most study don't focus on varicocelectomy done for varicocele induced orchialgia,and those studies dont report on postoperative semen. This study will focus on the effect of operation on the semen postoperatively .

Hormonal monitoring impact on overall pregnancy rate in frozen embryo transfer (FET)cycles and hence progesterone supplement adjustments remain debatable in current literature. This prospective randomized study aims to investigate the effect of monitoring and follow-up of serum progesterone, estradiol & luteinizing hormone (LH) levels and progesterone supplement adjustments on pregnancy outcomes for FET in programmed hormonal replacement therapy cycles in comparison with ultrasound only in control group

The aim of this trial is to examine the possible effects of hCG administration for eight weeks prior to IVF/ICSI in women with low ovarian reserve. Primary outcome is the proportion of the antral follicle count that reach the pre-ovulatory stage.

. This study aimed to determine and compare the effect of vaginal sildenafil citrate and estradiol valerate on endometrial thickness, blood flow and pregnancy rates in infertile women.
