Active clinical trials for "Infertility"

Infertility is expressed as an inability to conceive or carry a healthy pregnancy to the end. It is often said that the couple suffers from infertility if for a year they could not get a normal pregnancy. 30% of the reasons for this unsuccess are attributed to women, 30% are attributed to men, while the other 40% of cases are attributed to the combination between men and women and for unknown reasons. In women, the source of most of the problems of infertility are associated with different failures in ovulation (early ovulation, lack of ovulation or irregular ovulation). Other reasons are Blocked fallopian tubes (due to endometriosis, infection or surgery), problems in the uterus and endometrium. There is a group of women that apparently does not have the failures described above, and they have infertility that does not include pathological findings. Apparently chronic stress is a potential cause among couples who could not get pregnant (despite 6 months of focused sex) so there is a request for various techniques for reducing stress including yoga and meditation. One common option in various conditions of infertility is in vitro fertilization. This technique is also known as artificial insemination and is the most common technique used in Israel. Data from the Ministry of Health from the last years, indicate that the rate of successful pregnancies after embryo transfer is more than a third (in average), this is from an average of 20 treatment cycles. Researches in alternative medicine are not easy to carry out. The placebo group which is usually the control group tend to be a treatment group by itself and gives effective results than a group that does not receive treatment at all. Carrying out a strict study with a good control group such as reflexology research in multiple sclerosis, has brought significant results in various statistical measures examined in this study (movement, sensory mode and urinary tract symptoms). In the control group the calf was chosen as a place of a massage as a dummy treatment (gynecological place), which prevented contact with specific points of the feet like in patients in the treatment group. This study wishes to answer the research question: Does reflexology treatment increase the chances of pregnancy implantation in women without pathological findings that are treated with IVF. Other questions related to measures that could lead to the implant of pregnancy, are whether reflexology treatment affect the endometrial thickness, number of oocytes and embryo quality. Literature indicates the potential of reflexology treatment on ovulation induction (But requires a good control group and large sample size).

To evaluate the effect of oral Phytoestrogen or Isosorbid mononitrate or N-acetyl cysteine as an adjuvant to clomiphene citrate on induction of ovulation and pregnancy outcomes in patients with PCOS. In this three-arm open RCT, 240 PCOS infertile women were randomly divided to 3 groups for induction of ovulation. Group A, [PE group, n= 80] patients received CC 100mg/d plus oral Phytoestrogen120 mg/ day and patients in Group B, [ISMN group, n=80] received CC 100 mg/d plus 20 mg Isosorbid mononitrate and Group C, [NAC group, n=80] patients received CC 100 mg/d plus NAC 1200 mg/day.

Four hundred and fifty women with mild male factor infertility will be divided into 3 equal groups using computer generated random numbers: Group 1 will have up to 4 stimulated IUI cycles, group 2 will have up to 4 unstimulated cycles, women who do not become pregnant after the 4 cycles in groups 1 and 2 will be advised to have regular intercourse at the expected time of ovulation. Group 3 will be the control group will be advised to have regular sexual intercourse at the time of ovulation for 6 months

The purpose of this randomized clinical trial is to compare the efficacy and safety with transfer of embryos selected by next generation sequencing (NGS) versus conventional morphological criteria. Subjects with 3 or more blastocysts on day 5 of embryo culture will be randomized to the PGS or IVF group. A Freeze-all strategy and a single frozen blastocyst transfer will be performed in both PGS and IVF groups. The primary outcome is the cumulative live birth after transfers of up to 3 single blastocycsts in both groups.

This is an open label, single arm, single center investigation to assess the safety and efficacy of purified adult autologous bone marrow derived CD34+, CD133+, and mesenchymal stem cells injected into the seminiferous tubules and testis, through a 12 week follow-up period. The investigators' selected model of research is based on maximizing the efficiency of the approach by choosing an autologous pattern which preserves the genetic make-up of an individual that is vital in infertility conditions. Additionally the approach involves injecting a combination of different but purified cell types which all aid in the retrieval of spermatogenesis, and the generation of mature spermatozoa. Expected outcomes of this study are defined in general improvements in infertile patients in regards of testicular morphology, sexual function, semen quality, development of primary or secondary spermatocytes, spermatids, or mature spermatozoa in the testis, seminiferous tubules, or semen.

The purpose of study is to compare the effectiveness of the Day-5 fixed administration of GnRH antagonist versus flexible administration of GnRH antagonist during ovarian stimulation in Chinese women with predicted high ovarian response, and the hypotheses is that the number of oocyte retrieved in fixed protocol is not inferior to GnRH antagonist flexible protocol.

Endometriosis is a common, chronic disease. 30% to 50% of women with endometriosis are infertile. There is moderate quality evidence that laparoscopic surgery to treat mild and moderate endometriosis increases live birth or ongoing pregnancy rates. There was no evidence of benefit for post-surgical hormonal suppression of endometriosis compared to surgery alone for the outcomes of pregnancy rates. Past studies have confirmed that Chinese herbal medicine can inhibit post-surgical endometriosis recurrence, increase pregnancy rate.This study evaluates the efficacy and safety of Traditional Chinese Medicine Sequential Treatment of endometriosis-associated infertility. The study objective is to confirm that clinical pregnancy rate of patients with endometriosis-associated infertility post-conservative surgery accepting Chinese medicine activating blood, dredging liver and nourishing kidney sequential treatment is higher than expectant treatment.

Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies, affecting 5% to 10% of women of reproductive age. Women with PCOS suffer from anovulatory infertility. Following lifestyle modification with weight reduction in obese PCOS women, clomifene citrate (CC) is considered the first line treatment for ovulation induction (OI) in these women. 75-80% of women will ovulate after CC administration. However, there is a discrepancy between the ovulation rate and pregnancy rate, which was reported to be 22% per each ovulating cycles after CC. Other alternatives, including gonadotropin injections and laparoscopic ovarian drilling, carried different disadvantages, such as costly treatment and risks of ovarian hyperstimulation syndrome and multiple pregnancy rate in gonadotrophin therapy and surgical risks and risk of ovarian failure in surgical treatment. The use of aromatase inhibitor, letrozole (LTZ), in reproductive medicine started in 2001. After this publication, there have been many groups of investigators studying the use of LTZ either in OI or ovarian stimulation in IVF cycles. A large multicentre randomized trial reported a significantly higher ovulation rate and live-birth rate comparing LTZ with CC. In majority of the publications, the multiple pregnancy rate was lower in LTZ group than in CC group. This can be attributed to the higher chance of monofollicular development after LTZ compared with CC. However, there is no information comparing the hormonal profile and follicular development after letrozole and CC. Mild ovarian stimulation using LTZ or CC in conjunction with intrauterine insemination is commonly offered to ovulatory women with unexplained infertility, minimal endometriosis or mild factor to improve the pregnancy rate. There is again no information comparing the hormonal profile and follicular development after letrozole and CC in ovulatory women. The aim of this study is to compare the hormonal profile after the use of LTZ and CC in anovulatory PCOS women and ovulatory women with unexplained subfertility. The hypothesis is that the FSH risk after LTZ is shorter than that of CC.

The purpose of this prospective cohort study is to compare IVF outcome between tamoxifen and clomiphene citrate in mild stimulation.

In this study the investigators propose a randomized controlled trial to evaluate the effect of influenza vaccination on clinical pregnancy rates among women undergoing in vitro fertilization as donor egg recipients.
