Active clinical trials for "Infertility"

The investigators are trying to determine stress management strategies in couples undergoing In Vitro Fertilization (IVF).

The purpose of this study is to compare two fertility protocols in obese women with Polycystic Ovarian Syndrome who are candidates for In Vitro Fertilization (IVF). These protocols carry less risk of ovarian hyperstimulation syndrome which these women may experience.

There are three main cycle regimens used for endometrial preparation for frozen embryo transfer（FET）: natural cycles (NC) with/without ovulation triggering, hormone replacement therapy cycles (HRT) in which the endometrium is artificially prepared by estrogen and progesterone hormones with/without a gonadotrophin releasing hormone agonist (GnRH-a) down regulation, and ovulation induced cycles (OI) in which follicular development is supported with increasing doses of gonadotrophin hormones and ovulation is induced. At present, there is still no sufficient evidence that which kind of FET cycle regimen to plan more advantage. The purpose of this study was to compare the pregnancy outcome of NC-FET to that of HRT-FET in women with regular cycles.

There are two main cycle regimens used for endometrial preparation for frozen embryo transfer （FET) in women with irregular cycles: hormone replacement therapy cycles (HRT) in which the endometrium is artificially prepared by estrogen and progesterone hormones with/without a gonadotrophin releasing hormone agonist (GnRH-a) down regulation, and ovulation induced cycles (OI) in which follicular development is supported with increasing doses of gonadotrophin hormones and ovulation is induced. At present, there is still no sufficient evidence that which kind of frozen embryo transfer cycle regimen to plan more advantage. The purpose of this study was to compare the pregnancy outcome of hormone replacement therapy cycles (HRT) and ovulation induced cycles (OI) in women with irregular cycles.

The purpose of this study is to compare the natural cycle (without any medication) with the well-established artificial cycle in an egg donation program.

The investigators use granulocyte colony-stimulating factor (GCSF) for the treatment of recurrent implantation failure in IVF patient with cause unknown or due to thin endometrium. Several studies showed that GCSF improves embryo development and implantation and increase pregnancy rate.

A phase 3 multicenter unblinded randomized controlled trial comparing the temporary uterine blood supply occlusion with conventional approach during laparoscopic myomectomy in patients with uterine leiomyoma.

Hysteroscopy is still considered the gold standard procedure for uterine cavity exploration. Therefore, many specialists have used hysteroscopy as their first-line of routine exam for infertility patients regardless of guidelines. Thus, scheduling the office micro hysteroscopy as one of the routine steps in the fertility workup program has become mandatory before the final diagnosis of unexplained infertility.

To assess the impact of cervical mucus cleansing before embryo transfer and compare two different instruments for this purpose.

This prospective study evaluates the pregnancy results after laparoscopic endometriosis operation in infertile patients with ERROR (endometrioma related reduction in ovarian reserve)
