Filter by:This was an open, randomized, comparative study using rhCG (Ovidrel) in the induction of final follicle maturation and early luteinization in Chinese female subjects undergoing IVF or ET.
This was an open-label, randomized, comparative, phase III study to evaluate the safety and efficacy of Crinone 8% in comparison with progesterone 60 mg intramuscular (i.m.) administered once a day in luteal phase support in 200 Chinese female subjects undergoing IVF/ET.
This was a prospective, randomised, open comparative monocentric phase IIIb study to evaluate the convenience, safety and efficacy of follitropin alfa (Gonal-f) liquid pen compared with follitropin beta (Puregon) liquid pen.
The primary objective of this observational study is to assess the cumulative rate of ongoing pregnancy at 10 ±2 weeks after hCG administration in a new series of IVF-treatment cycles in a total of 176 subjects, who have undergone three or more previous IVF-treatment cycles without live birth. Secondary objectives include subgroup analysis on the effect of age on the likelihood of pregnancy at 10 ±2 weeks after hCG administration in a new series of IVF-treatment cycles in patients < 35 years and ≥ 35 years, who have undergone three or more previous IVF-treatment cycles without live birth. The information obtained from this trial will be helpful for subjects who are considering further IVF treatments and for IVF centres, as well as for the formulation of governmental policies regarding healthcare reimbursement in Norway.
Intrauterine injection of hCG around the time of implantation may increase endometrial Treg cells and improve implantation. It has been demonstrated that regulatory T cells expand during pregnancy. hCG was found to be secreted by the embryo immediately after fertilization and has chemoattractant properties to Treg cells.
The purpose of this study is to assess the effect of luteal phase supplement (LPS) on pregnancy rate in IUI cycles stimulated with clomiphene citrate.
The objective of this application is to identify a pharmacologic agent which helps couples in whom the female partner ovulates regularly successfully obtain their goal of delivering a healthy child, whose use will result in low rates of multiple gestations. The central hypothesis is that, in infertile ovulatory women undergoing ovarian stimulation (OS) and intrauterine insemination (IUI), the use of aromatase inhibitors (AI) will stimulate the ovaries sufficiently to produce no reduction in the rate of pregnancy, while significantly reducing the numbers of multiple gestational pregnancies that result from stimulation with clomiphene citrate (CC) or follicle stimulating hormone (FSH). The rationale for the proposed research is that reduction of multiple pregnancy rates could significantly reduce maternal and neonatal morbidity and mortality, as well as the cost of healthcare for these individuals and society.
The aim of this study is to determine whether the ultrasound guided aspiration of hydrosalpingeal fluid at the time of oocyte retrieval can improve the outcomes of IVF-ET .
The purpose of this study is to compare two different ways to administer Letrozole to determine their effectiveness in blocking estrogen production during ovarian stimulation in patients with breast cancer prior to chemotherapy/radiotherapy so that oocytes or embryos can be cryopreserved and patients can possibly achieve a pregnancy after the treatment of breast cancer. During standard ovulation stimulation, the estrogen levels will exceed normal levels and may reach 10 times the normal level for a 2 week period. This may not be desirable in breast cancer patients. The study hopes to determine if the investigators can stimulate oocyte development in the conventional way and administer different doses of Letrozole as the oocytes develop, to keep estradiol levels low, increase the number of oocytes the investigators are able to recover, and improve the quality of those oocytes.
The investigators will use a thin catheter for HSG and apply pressure on the cervix with the vaginal speculum to prevent leakage of the dye during injection to study the uterine cavity and fallopian tubes and reduce the pain as compared to a standard metal cannula.
