Active clinical trials for "Infertility"

The purpose of this study is to compare the efficacy of in vitro fertilization (IVF) versus laparoscopic ovarian drilling (LOD) in infertile women having clomiphene citrate (CC) resistant polycystic ovarian syndrome (PCOS).

To compare the effectiveness of single step culture media and continuous uninterrupted culture media on blastulation rate

The purpose of this study is to determine whether Medroxyprogesterone Acetate (MPA) administration in follicular phase prevents premature luteinization with equal efficiency as GnRH antagonists and otains similar clinical results in oocyte donation.

The goal of the study is to measure serial hormonal levels in patients undergoing clomiphene, letrozole, and a combination clomiphene and letrozole cycle. This information may help us to optimize less expensive medications for ovulation induction, reduce the number of treatment cycles to achieve a successful pregnancy, and use a medication regimen that may result in fewer multiple gestation pregnancies.

The purpose of this study is to compare the effect of oral Calcium Dobesilate to oral Cabergoline in the prevention of ovarian hyperstimulation syndrome (OHSS) in high-risk women underwent intracytoplasmic sperm injection (ICSI).

The aim of this study is to perform a 12-hour profile of free saliva progesterone during the luteal phase after fresh and frozen embryo transfer. If progesterone levels in saliva samples show a constant level during daytime, this non-invasive measurement can be used in future ART patients with insufficient progesterone levels who might benefit from additional exogenous progesterone supplementation.

This study will assess the change in endometrial gene expression signature on the day of embryo transfer according to the type of exogenous gonadotropins administered.

Infertility is the failure to conceive after regular unprotected sexual intercourse for one year. Primary infertility refers woman who has never conceived, and secondary infertility to one who has had a previous pregnancy.The most frequent causes for infertility are ovulatory disorder or anovulation (27-30%) , tubal factor(20-22%), abnormal semen parameters(45-50%). Unexplained infertility refers to infertile couples in whom standard investigations, including tests of ovulation, tubal patency tests and semen analysis are normal. incidence 15-17% of infertile couples. New guidelines on infertility recommend that women with unexplained infertility should be advised for expectant management for 2 years .If pregnancy is not achieved after this period In vitro fertilization Should be considered. The Fast Track and Standard Treatment trial demonstrated A shorter time to pregnancy and higher per cycle pregnancy rates for In vitro fertilization compared with treatment with oral agents or gonadotropins in Patients with unexplained infertility. Successful pregnancy after assisted reproductive technology is influenced by numerous predictors that have been investigated in the previous years. The central predictors of success are the sperm, oocyte quality and endometrial receptivity. Oocyte quality depends mainly on the age of the woman , and her ovarian reserve. Parameters most commonly studied are the woman's age , her antral follicle count , and laboratory tests including serum randomly done during the menstrual cycle levels at day 3 of the cycle.

The aim of our study is to determine the efficacy of oral diclofenac potassium with or without vaginal dinoprostone prior to hysterosalpingography in primarily infertile patients on the pain scores during HSG.

Women with polycystic ovary syndrome (PCOS) can suffer from infertility because they do not produce an egg each month, resulting in irregular periods. As a result, these women often need a medication called clomiphene citrate (clomiphene) to induce ovulation. A traditional 'clomiphene protocol' begins with a short course of progestin treatment to bring on a period (termed a 'withdrawal bleed') before starting the clomiphene medication. Newer evidence, however, has suggested that this progestin-induced shedding of the uterine lining (i.e., withdrawal bleed) may decrease the chances of pregnancy. The purpose of our study is to determine whether withdrawal bleeding has an impact on pregnancy rates for patients with PCOS undergoing a clomiphene cycle. It is hypothesized that patients who undergo ovulation induction with clomiphene citrate without prior endometrial shedding will have higher clinical pregnancy rates than those who begin with a progestin-induced withdrawal bleed.
