Active clinical trials for "Infertility"

The aim of this research is to compare sibling oocytes using two sperm selection methods for choosing the best quality spermatozoa before they are injected into oocytes and the influence of each of these methods on embryo quality and IVF outcome.

Embryo freezing is a technique used commonly to optimize the pregnancy rate in assisted reproduction techniques (ART). Hormone replacement therapy (HRT) regimen is applied to prepare endometrium for frozen embryo transfer (FET) commonly.At present, It is unclear whether preimplantation low molecular weight heparin (LMWH) improves live birth and pregnancy rates in subfertile women undergoing FET. The study is a prospective randomized controlled trial to compare the pregnancy outcomes of FET in hormonal replacement therapy(HRT) cycles with or without LMWH administration before implantation.

This will be a prospective, randomized (1:1 ratio) clinical trial for non-male factor infertility in advanced maternal age with or without intracytoplasmic sperm injection(ICSI). Qualified 1422 patients are randomized into either of two groups: group A will undergo conventional in-vitro fertilization(IVF)(711 cases), Group B will undergo intracytoplasmic sperm injection (ICSI) (711 cases). All participants will receive the same protocol for ovarian stimulation and standardized luteal phase support. The target population will be patients with non-male factor infertility aged ≥38years with FSH ≤15. Women with other reasons of infertility (eg. anovulation, endometriosis, and premature ovarian failure) are excluded. The randomization will take place before controlled ovarian stimulation by a computer randomization system. The accumulated live birth rate , pregnancy complications will be followed up by checking medical records and telephone calls.

The aim of this study is to measure the expression of HOXA10 and HOXA11 in the endometrium of infertility patients with an endometrial polyp before and after polypectomy. HOXA10 and HOXA11 are well-established markers of implantation. It is uncertain as to whether an endometrial polyp interferes with embryo implantation. A higher expression of HOXA10 and HOXA11 after polypectomy can indicate that endometrial polyp does interfere with embryo implantation.

Congenital uterine anomalies are found in 8% of infertile women and 24.5% of infertile women with a history of recurrent miscarriage, with septate and sub-septate uterus being the most common anomalies in these women, Also, septate uterus is the commonest anomaly found in infertile women requiring assisted reproductive technology. Published data showed improved Cumulative pregnancy rate and live birth rate, and a significant reduction in Miscarriage rate in In Vitro Fertilization women after hysteroscopic metroplasty of both small and large septate compared to non-operated women. Investigators hypothesized that trans-vaginal three Dimensional Ultrasound will be superior to Hystro-salpingography for the differentiation between arcuate and septate uterus in infertile women scheduled for In Vitro Fertilization.

The purpose of this prospective, randomized study, was to determine if neck and shoulder massage performed within 15 minutes of semen sample collection will increase the semen volume, and therefore increase the total motile sperm available for insemination as a result of decreased stress.

The purpose of this study is to determine whether minimal ovarian stimulation for in vitro fertilization is superior to high dose stimulation. Number of mature eggs, number of embryos as well as pregnancy rates will be compared.

The aim of this study is to determine whether different needle gauges influences the quality of the aspirated oocytes during in-vivo fertilization (IVF).

The purpose of this study is to determine if the addition of dexamethasone to clomiphene citrate will increase the pregnancy rate of intrauterine insemination (IUI) cycles.

The objective of the study is to evaluate the agreement in measurement of sperm concentration in human semen between lay users with TRAK and a recognized reference method. The study will also include the measurement of matched samples by TRAK when tested by healthcare professionals trained in use of the TRAK device.
