Active clinical trials for "Infertility"

The aim of this study is to assess the impact of the timing of intrauterine insemination (IUI) in relation to the natural surge of luteinizing hormone (LH), as detected by home ovulation predictor kits, on pregnancy rates per treatment cycle. The study will take place at the offices of Midwest Fertility Specialists and include patients who have been independently recommended by their primary physician to undergo ovulation induction with clomiphene citrate (CC) or letrozole and IUI as therapy for infertility.

At which deleterious cut off value of progesterone on day of HCG (P-hCG) in our IVF program should fresh embryo transfer (ET) be cancelled?

This study evaluates the quality of sperm produced after semen processing using Density Gradient (DG) and swimming down (SD).

To assess the effectiveness of a protocol of ovarian hyperstimulation combining urinary gonadotrophins + recombinant gonadotrophins, to achieve clinical pregnancy in females undergoing IVF. Study hypothesis: to assess the effectiveness of protocols combining urinary gonadotrophins + recombinant gonadotrophins

The purpose of this study is to assess the effectiveness of Menopur to achieve clinical pregnancy in females undergoing intrauterine insemination in clinical practice.

The role of vitamin D deficiency in female reproduction remains controversial. Early retrospective studies were inconsistent regarding the effect of serum 25-OH vitamin D levels on pregnancy rates in women undergoing in vitro fertilization (IVF), whereas two retrospective studies postulated that vitamin D deficiency may negatively affect pregnancy rates with an effect mediated through the endometrium. Taking into account that knock-out experiments have shown that vitamin D receptor null mice not only experience uterine hypoplasia but also impaired folliculogenesis, it might be hypothesized that vitamin D deficiency may have a detrimental effect on female ovarian reserve. This may be further supported by previous reports demonstrating that serum 25-OH Vitamin D levels correlates with antimullerian hormone (AMH) levels in women of advanced reproductive age. The aim of this study is to examine through a large set of prospectively recruited infertile women whether serum 25-OH-Vitamin D levels is related with the 2 most widely accepted biomarkers of ovarian reserve: serum AMH levels and antral follicle count (AFC).

This study evaluates the incidence of Non Receptive endometrium in obese infertile women compared to infertile normal weight women using Endometrial Receptivity Array (ERA) test, containing 238 genes, identifying the receptivity status of an endometrial sample and diagnosing the patient's Window of Implantation, regardless of the histological appearance of the sample. An endometrial biopsy is collected from the uterine fundus, either in a natural cycle or in a hormonal replacement therapy (HRT) cycle and the test is performed.

The purpose of this study is to evaluate the safety and efficacy of highly purified (HP) menotrophine to Korean women.

This study seeks to compare the pregnancy and delivery rates of patients who undergo a single embryo transfer, when the embryo has been tested and determined to be chromosomally normal, with pregnancy and delivery rates of patients who undergo a two (2) embryo transfer of untested embryos.

Fertility drugs have the effect of increasing hormone levels. Higher hormone levels from infertility treatments may increase breast cancer risk, but there has not been enough research to know for sure. Researchers want to use a method of taking breast tissue cells from women who are having infertility treatment. The breast tissue cells might show changes that would indicate an increased risk of cancer. The method of taking the breast tissue cells is called Fine Needle Aspiration (FNA). The purpose of this study is to examine the changes in breast tissue, in women at high risk of breast cancer who are being treated with controlled ovarian hyperstimulation.
