Filter by:To test the hypothesis that adding estradiol (E2) to progesterone supplementation later in the luteal phase of in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles, rather than earlier in the luteal phase, improves clinical pregnancy rates (PRs).
Comparative study to determine whether several fertility monitoring products - the DuoFertility monitor, the LadyComp/Babycomp monitor and Clearblue Ovulation tests - are substantially equivalent in performance, and secondarily to determine the appropriateness of labeling information for the DuoFertility monitor.
NaProTechnology (NPT) is a treatment option for infertility or miscarriage that identifies issues in a couple's fertility and fixes them to the extent possible by medical intervention. An important part of NPT is teaching couples to monitor the signs and symptoms of the woman's fertility cycle (menstrual cycle) with the Creighton Model FertilityCare System (CrMS). The purpose of the study is to look at outcomes among couples who consider or get NPT treatment to help them have a live birth. Results from the study will be used to answer questions such as: How many couples who use NPT get pregnant and have a baby? How can NPT treatment be improved? Does NPT treatment have fewer long-term health risks for the resulting children than other fertility treatments? What types of characteristics or environmental exposures influence whether NPT will be successful for a specific couple? To be eligible for the iNEST study, a couple must have a consultation with a NPT-trained clinician who is participating in iNEST.
Infertility is the most common reason women (aged 20-45yrs)see their GP, affecting 1 in 7 couples. Measuring basal body temperature is a technique that has been used since the 1930's to attempt to predict ovulation. Current NICE guidelines don't recommend the use of BBT charts to predict ovulation, as it has not been established to reliably confirm ovulation. The DuoFertility sensor a CE marked Class la device provides a continuous accurate measure of axilla temperature whilst worn under the arm. The investigators plan to compare the temperature measurements of the DuoFertility sensor with the gold standard transvaginal ultrasound scan obtained during 10 infertile women's menstrual cycles, up to 10 cycles per women. The investigators aim to investigate if continuous axillary skin temperature measurement obtained from the DuoFertility sensor, provides comparable results for identifying the occurrence of ovulation as the gold standard transvaginal ultrasound scan.
The proposal of this study is to evaluate the association between the achievement of ongoing pregnancy and hormonal levels on the first day after the period had stopped in rec-FSH/GnRH- antagonist cycles.
Quality-controlled commercial media have been used in many in-vitro fertilization (IVF) laboratories. However, commercial media are costly and difficult to compare directly because their exact compositions are not clearly indicated. Although commercially available media have commonly been used in most IVF programs worldwide, there are several advantages to the use of in-house synthetic sequential media at IVF laboratories. First, the results of quality control should be reliable due to a stringent protocol setting-up. Second, any direct supplementations or deletions of specific components are feasible to obtain good quality embryos and high pregnancy rates since those components can be defined. Finally, dependence on commercially available media diminishes so that the laboratory can more easily accommodate unexpected situations or problems, such as a sudden increase in IVF patients. Therefore, the present study was conducted to compare the efficacy of in-house MRC media in the human IVF-embryo transfer (ET) program to that of commercially available media.
The aim of the current study was the pharmacokinetic and pharmacodynamic characterization of a single dose administration of four doses of FSH-GEX™ in healthy pituitary-suppressed female volunteers, in comparison with two marketed comparator products.
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 goal of the study is to quantitatively evaluate pituitary hormone response, follicle stimulating hormone (FSH) and luteinizing hormone (LH), to low doses of clomiphene citrate in normally fertile women.
The study is a prospective, randomised, controlled, and non-blinded multi-center pilot study to evaluate endocrine efficacy of recombinant luteinizing hormone versus recombinant human chorionic gonadotropin administered during controlled ovarian stimulation for IVF/ICSI in normogonadotrophic women.
