Filter by:This is a phase 1b clinical trial with Choriogonadotropin beta (FE999302) and Follitropin delta (Rekovelle). The trial is multicentre, randomized, partially double-blind, placebo-controlled, parallel-group investigating the effect of FE999302 on parameters influencing pregnancy rates in women undergoing controlled ovarian stimulation with a fixed dose of follitropin. The primary endpoint is the number of good-quality blastocysts on day 5 after oocyte retrieval. Secondary endpoints are number of follicles by size category and serum concentration of different hormones on stimulation day 6 and end-of stimulation, the number of stimulation days and oocytes retrieved, the number of metaphase II oocytes and fertilised oocytes, number of blastocysts on day 5, number of cryopreserved blastocysts, endometrial thickness at eos, positive bhcg rate, clinical pregnancy, vital pregnancy and ongoing pregnancy.
Background: Advanced maternal age (AMA) is associated with a reduction in live birth rate (LBR) after ART cycles. The main reason for this reduction is the lower number of oocytes aspirated, the number of developing embryos and the low number of euploid embryos available for transfer. The impact of age on success rates after the transfer of an euploid embryo has been a matter of discussion, with a recent meta-analysis showing a reduction in LBR after the transfer of an euploid blastocyst to women of AMA (1). There could be many reasons for this reduced LBR but they can be categorized into two broad categories - the uterus (including the mother's health) and the embryo (including the oocyte and the sperm). It is possible that factors associated with reduced embryo quality would manifest in a lower embryo grade.
Oocyte vitrification is an effective method of freezing which has been authorized in France since 2011. The arrival of this technique has led to real improvements in the survival rate of oocytes after warming compared to that observed after slow freezing, a method previously applied. Oocytes reheated after vitrification show excellent results in terms of vitality and recovery of cellular functionality. Indeed, the fertilization rates observed after using warmed and fertilized oocytes in Assisted Reproduction Technology (ART) by intracytoplasmic sperm injection (ICSI) are similar to those obtained with fresh oocytes. However, the manual vitrification techniques used until now involve a learning curve and a potential variability of the completion time depending on the operator and the number of oocytes to be vitrified. Oocyte vitrification is a key step to optimize the chances of pregnancy in ART after using these oocytes. However, manual vitrification requires a learning curve, is technician-dependent and requires significant technical time. A semi-automatic vitrification device (GAVI®, Merck), which recently appeared on the market, has demonstrated its effectiveness in terms of speed of production and reproducibility of vitrification of embryos obtained in ART. To our knowledge, no study has analyzed the effectiveness of semi-automatic vitrification (GAVI®, Merck) on survival and oocyte quality after warming. It would therefore be interesting to evaluate the effectiveness of this automaton on oocyte vitrification in the context of oocyte donation and to determine the impact of semi-automatic vitrification on oocytes compared to manual vitrification. The main objective of this study is to demonstrate the non-inferiority of vitrification semi-automated device (Gavi) of oocytes with regard to the oocyte survival rate, compared to the manual technique used in ART. The investigator will compare the effectiveness of semi-automated vitrification device with the manual technique, in terms of ART results by comparing the fertilization rates, the number and quality of embryos obtained as well as the implantation rates in oocyte recipient patients. This study will then allow clinical application of the most efficient protocol for oocyte vitrification in the context of oocyte donation. A cost/effectiveness study will be carried out.
Collection and conservation of human biological material from fertile subjects, i.e. men with previous parenthood (normospermic men, natural fathers).
The goal of this observational study is to determine whether the frequency of ejaculation in men had an effect on semen parameters.. The main questions it aims to answer are: - question 1：Whether the frequency of ejaculation has an effect on semen parameters - question 2：Whether the penultimate abstinence period has an effect on semen parameters The participants were men who underwent semen examination in the andrology clinic of the Reproductive Center of the First Hospital of Jilin University. A brief medical history was collected from each volunteer, including demographic information, fertility history and as well as information regarding their general health.The focus of the investigation is the time of abstinence for this examination, the penultimate abstinence period, and the number of ejaculation since the last 1 month.
This randomized trial was designed as a no-inferiority trial aiming to evaluate if the intensity of stimulation (a milder vs a more intense approach) may have an impact on the number of euploid embryos and the morpho kinetic parameters in advanced age women undergoing PGT-A with a PPOS protocol.
This randomized was designed as non-inferiority trial aiming to compare the number of MII oocytes with 2-shot of Corifollitropin alpha (CFA) sequential administration: 150μg at stimulation day (SD) 1 and 100μg at SD 5 and 1-shot of CFA administration 150μg at SD 1 following by rFSH 200IU daily from SD 8 in women undergoing elective fertility preservation in a progestin-primed ovarian stimulation (PPOS) protocol and GnRH-agonist (GnRH-a) triggering.
The purpose of this study is to evaluate the effectiveness of a multi-component intervention to improve young breast cancer survivors' engagement in goal-concordant oncofertility care, concurrently with observing and gathering information on how the intervention is implemented. The investigators hypothesize that implementation of the intervention will result in increased young breast cancer survivors' engagement in goal-concordant oncofertility care.
Fertility management refers to the entirety of practices that allow families to have as many children as they want and when they want, prevent unwanted pregnancies, regulate the time between two births and receive help in having children in the case of infertility. According to the Turkey Demographic and Health Survey 2018 data, 70% of women in Turkey who are currently married do not use any contraceptive method. Based on the same data, the rate of the unmet need for fertility management is 12% nationwide, 14% in eastern provinces, and 17% in women at the ages of 20-24. These rates show that the rates of unmet fertility management needs in Turkey are still not on the desired level. The fact that eastern provinces of Turkey have the lowest rate of modern contraceptive method use as 43% and a high rate of unmet fertility management needs as 14% suggests that it is needed to increase the effectiveness of fertility management counseling and reach more women. In these eastern provinces, especially women living in rural areas do not have easy access to these services due to the high prevalence of adolescent marriages, lack of transportation opportunities, healthcare personnel and healthcare services, and unpredictable weather conditions.
This study aims to investigate the microbiome of women with previously proven fertility who plan to become pregnant.
