NCT06584994
Gametogenesis is the production of sperm and eggs; it takes place through the process of meiosis. Gametogenesis is subject to the acquisition of mutations as with other processes in the body. Many of these mutations are somatic, meaning that they occur during life as part of the process of cell division rather than being passed down from parents. When somatic mutations take place during gametogenesis, there is the potential for hereditary genetic consequences. However, the processes that cause the mutations during gametogenesis and the implications they have for heritability and disease predisposition are poorly understood. The goal of this research is to provide a detailed description of the genetic changes in gonadal tissues, and to understand how mutations acquired during the production of germ cells (sperm and eggs) contribute to the predisposition to a wide range of rare diseases and cancer predisposition in future offspring.
NCT06304220
The scarcity of evidence regarding the interchangeable use of different progestogens poses challenges, particularly in international egg donation and fertility preservation programs where standardizing protocols is crucial for achieving consistent efficacy, efficiency, and safety outcomes. Consequently, there's a pressing need for clinical studies to assess the effects of various progestogens on clinical outcomes in controlled ovarian hyperstimulation cycles. This study, a pioneering effort, aims to compare the effects of two progestogens on oocyte performance, safety, and efficiency in an egg donation program involving young, healthy, normo-responding patients.
NCT05205733
The investigators currently lack an understanding of barriers to completing the male factor infertility evaluation. Furthermore, as the investigators continue to expand access to fertility treatment particularly within low-resourced settings, it is important that all aspects of infertility within a couple are equally explored. The COVID-19 pandemic has disproportionately affected low-income communities and communities of color at greater rates in terms of not only disease morbidity/mortality but how medical systems are accessed and care is delivered.
NCT05511272
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.

NCT05412147
How to improve the fertility of infertile women has become a hot topic in the field of assisted reproduction. Animal experiment has shown that RECO-18 significantly improved the female fertility in mice, and the specific mechanism was related to reducing follicular atresia, promoting follicle development and improving oocyte quality. Therefore the investigators aim to conduct a pilot study to explore the effect of RECO-18 in infertile women undergoing assisted reproduction treatment. This study is a prospective, randomized, controlled clinical study. The treatment group takes RECO-18 while the control group takes the multi-vitamins. The primary indicator is the ongoing pregnancy rate at 12 weeks' gestation; the secondary indicators are the number of oocytes retrieved, the normal fertilization rate and the rate of high quality embryos, implantation rate, clinical pregnancy rate, and early miscarriage rate.
NCT05409729
This study aimed to evaluate the potential association of subclinical hypothyrodism and ovarian reserve in reproductive age in age groups more than 35 and age groups less than 35 using retrospective study included women with subclinical hypothyrodism and controls .Evaluation of potential association of antithyroid antibodies positivity on ovarian reserve Primary outcome: Measure the association of SCH with ovarian reserve markers (basal FSH ,LH/basal AFC /AMH)
NCT05164029
The study will conduct a multicenter prospective clinical cohort study to collect comprehensive health information and essential specimens from pre-pregnancy to postpartum offspring development. We will combine the reproductive medicine with the big data technologies and cloud computing to explore the key factors which will induce the occurrence the reproductive disorders and effect the health of women and offspring. Based on the discovery of the cohort study, we will construct a prediction model for improvement of ART，optimizing the effectiveness and safety of ART.
NCT03478592
The meta-analysis comparing the cryopreservation of human embryos by vitrification or slow-freezing suggested that more well design studies as randomized trials are necessary to identify the most successful method for cryopreservation. The efficacy of the vitrification with the GAVI system will be compared with the conventional slow freezing method through a randomized control trial. Couples in IVF attempt will be randomized at the day of embryo cryopreservation by the biologist. Supernumerary frozen embryos will be thawed and transferred in utero in case of failure of the "fresh" embryo transfer. The outcomes of the thawing and frozen/thawed embryo transfer will be assessed. In the two groups, the patients will benefit of the standard IVF procedures applied in the Assisted Reproductive Technologies (ART) center of Toulouse.
NCT04446169
This study is part of the current global emergency scenario due to infection with Coronavirus, SARS-CoV-2 as indicated by the international taxonomy. Study aim is to investigate the possibility of the presence of the virus within the seminal fluid and in the urine of infected patients, both during the acute phase and remotely. Current evidences show that Coronaviruses can be present inside the testicle and sperm in other species, such as in feline and avian models. In human beings, current researches have mixed results regarding the presence of SARSCoV-2 in urine, as several studies with a large sample found no traces of the same with Real-Time Reverse method Transcriptase - Polymerase Chain Reaction or with method of nucleic acid amplification. By contrast, in just over 6% of 58 patients with Real Time Polymerase Chain Reaction method have found the presence of SARS-CoV-2 in the urine, even at a distance from the last negative nasopharyngeal swab. Given the topicality of the problem, our study has the objective of specifically researching the presence and possible persistence over time of SARS-CoV-2 in seminal fluid and urine. A saliva sample will also be collected as a control. At the moment there are no studies in literature that tested this possibility. If confirmed, it would lead to find out another potential method of transmission, the sexual one, in asymptomatic patients or apparently no longer infectious with negative buffer. The rationale for our study is the evidence that in other species this type of transmission by coronaviruses is possible and that at present it has not been verified in mankind. The relevance of the study would be both in the case of a negative result, as the first study in its generally, both in the case of a positive result, due to the possibility of introducing new prevention measures in the long run.

NCT04604054
One hundred patients who suffered from recurrent implantation failure in intracytoplasmic sperm injection (ICSI) were allocated in the study. On ovum pick-up day, 50 of them were intrauterine injected with granulocyte colony-stimulating factor (G-CSF) and the other 50 were injected with intrauterine Human Chorionic Gonadotropins (HCG). The clinical pregnancy rate was evaluated as a primary outcome and ultrasound imaging of the gestational sac was evaluated as a secondary outcome
NCT04131452
Women's quality of life, sexual life and psychological state would affect the success of embryo transfer. The primary purpose of the study is to compare women's quality of life, sexual life and psychological state using validated forms between those undergoing fresh embryo transfer and those undergoing frozen embryo transfer.
NCT03480412
Reduced ovarian reserve and the consequent poor ovarian response are very recurent in infertile patients, indeed a percentage of 10%-24% of couples addressed to infertility program may be classified as Poor Ovarian Responder (POR). Objective: To evaluate whether the repeated luteal phase stimulation (Second Step) permits a significantly higher number of oocytes retrieved in POR when compared to conventional follicular stimulation. Interventions: The follicular phase stimulation is conduced according to a standardized Antagonist protocol or Short protocol (with GnRH agonist) using recombinant or urinary gonadotropins (starting dose 300 or 450 UI) or a long lasting recombinant gonadotropin (Corifollitropin alfa 150 mcg). Two - six days after the first oocyte retrieval a second gonadotropin stimulation will be started with a GnRH antagonist protocol (the stimulation will be started with 250 UI of human menopausal gonadotropin (hMG) and a GnRH antagonist (GnRH-an) 0,25 mg\\die will be administered when the leading follicle is ≥ 14 mm until hCG (human chorionic gonadotropin) criteria are met. When at least two follicles had reached 17-18 mm in diameter, ovulation will be triggered with a single subcutaneous bolus of urinary human chorionic gonadotropin (10.000 UI ) and oocyte retrieval will be performed after 35 hours. Two or Three months after the second oocyte retrieval the Embryo transfer (ET) will be performed after endometrial preparation with Estradiol Valerate and intramuscular Progesterone.
