Filter by:The goal of this clinical trial is to investigate if cryopreservation of ovarian tissue in girls with Turner syndrome can improve their fertility and lead to increased number of liveborn babies of Turner syndrome mothers. Women with Turner syndrome suffer from premature ovarian insufficiency which leads to infertility and lack of estrogen. The main questions it aims to answer are: - Does the number of pregnancies and liveborn children increase after cryopreservation of ovarian tissue in turner syndrome? - Is the possible to predict when a girl with Turner syndrome reach menopause using monitoring of sex hormones? - Is it possible to identify any genes causing ovarian failure in Turner syndrome females? Participants between 2-18 years old will be asked to participate in a laparoscopic surgery and removal of one ovary in order to cryopreserve the tissue until adulthood. The the cortical tissue will be autotransplanted in order to preserve fertility. The participant will during the study period be monitored using sex hormones. Furthermore, the investigators wish to investigate the ovarian tissue using RNA sequencing and DNA methylation analysis. No comparison group is present.
Recurrent miscarriages (RM) affects 3% of all fertile couples, but remains unexplained in most cases, limiting therapeutic options. Possibly the maternal immune system plays a role in recurrent miscarriage. Prednisolone suppresses the immune system and might enable development of normal pregnancy. In this randomized controlled clinical trial the investigators will study the effect of prednisolone on the live birth rate in patients with RM. Secondary, the tolerability and safety for mother and child and the cost-effectiveness is investigated. In the study one group of pregnant women with RM and gestational age <7 weeks will receive prednisolone, the other group will receive a placebo. Total use of the medicine during this study is 8 weeks, further care during the study is routinely antenatal care. Subjects will be asked to fill in 4 short questionnaires and will have contact with a research nurse at different time points to gain information on the course of the pregnancy and possible side effects. Results of the study will be implemented in (inter) national guidelines, to effect everyday practice.
This is a randomized controlled trial comparing density gradient centrifugation and microfluidic sperm sorting in patients undergoing intrauterine insemination to evaluate cumulative pregnancy outcomes.
In-vitro fertilisation (IVF) treatment involves women undergoing hormone stimulation (drug dosing) to produce more oocytes (eggs) to increase their chances of fertilisation. The information that IVF clinicians currently collect on a woman's hormonal response to IVF drug dosing comes from in-clinic blood testing. This requires patients to make a visit to the IVF clinic every few days to have the blood samples taken. The blood is then analysed in a laboratory for the hormone levels and the results are then sent back to the clinic. This monitoring process of frequent onsite visits and blood draws can often be quite inconvenient and disruptive for patients. This observational study will assess a non-invasive in vitro diagnostic (IVD) device for measuring the common fertility hormones in urine. The test system is for use by both healthcare professionals in a clinical setting and nonprofessionals in a home care setting under the guidance of a health care professional. This study will provide pilot data on the usability of the IVD device from the intended end users as well as the correlation of urinary metabolite levels as measured by the IVD device and the serum concentration as measured by blood analysers.
Prospective controlled study to assess the reproductive outcomes of OD recipients in which the donors were subjected to the DYG protocol (20mg/day) compared with those subjected to the short protocol with cetrorelix (0.25 mg/day) from Day 7 or since a leading follicle reached 14 mm. The OD cycles were triggered with triptoreline acetate and the trigger criterion was ≥3 follicles of diameter >18mm.
The aim of the study is to investigate the role of oxidative stress in female infertility and the relationship between the stress as it is illustrated by questionnaires, serum markers, follicular fluid markers, and ovarian response in assisted reproduction.
Serum progesterone levels will be evaluated at four different time points during the day of an artificially prepared frozen embryo transfer cycle (HRT FET cycle) and a modified natural cycle frozen embryo transfer cycle (mNC FET cycle) (at 08:00, 12:00, 16:00 and 20:00).The pairwise percentage differences in serum progesterone levels for each patient will be calculated. The intra-day variability of progesterone will be analyzed using mixed models. Pregnancy outcomes will also be assessed. The sample size calculated consisted of 22 patients for the HRT-FET study and 22 patients for the mNC FET study.
Women's ovarian reserve and fertility were compared before and after 2 doses of vaccination
This is an observational, prospective, single-arm, multi-center, clinical study to evaluate the performance of CHLOE, an Artificial Intelligence (AI)-based software application, as adjunct information to support identifying embryos on Day 3 that are most likely to form blastocysts.
An observational analytic retrospective study was conduct using cross-sectional study. The subject were oocytes from in-vitro fertilization procedures using the ICSI method at the assisted reproductive technology clinic in a private hospital in Bandung for the period 2017 - 2019. Three variables were oocyte denudation time, ICSI time and embryo quality collected from samples that met the research criteria.
