Filter by:The purpose of this study is to investigate the effects of COVID-19 Vaccination on semen parameters and to determine how long these possible changes may last following vaccination.
Study rationale 1. An increasing proportion of the worldwide population is being infected with COVID-19. 2. There are ongoing and currently unanswered safety concerns about the effects of COVID-19 on reproductive health. 3. It will be immensely reassuring to rapidly report that COVID-19 has no detectable effects on male endocrine or sperm function. Conversely, if COVID-19 does impair male reproductive health, appropriate screening can be performed in couples trying to conceive, and further research can be undertaken. 4. The proposed study will be simple, rapid, and authoritative for the UK and worldwide.
Progesterone resistance is mediated through epigenetic modification through SirT1 activation and is thought to contribute to infertility and progression of endometriosis. Endometriosis is a leading cause of unexplained IVF failure secondary to inflammatory changes that induce SirT1. The current study is designed to investigate a small molecule inhibitor of SirT1, in the clinical setting of In Vitro Fertilization and Embryo Transfer. The SAFER trial will compare EX-527 to placebo in a randomized, double-blind trial. Primary endpoints include Live Birth Rate (LBR) and secondary outcomes include pregnancy rate (PR), miscarriage rate (MR) and implantation failure rate.
To offer patients with oligomenorrhoea or amenorrhoea an alternative to frozen embryo transfer in an artificial cycle, endometrial preparation using letrozole may be a valuable option. Letrozole, a potent, reversible nonsteroidal aromatase inhibitor with relatively short half-life, can successfully induce ovulation without any adverse anti-estrogenic effects and thus without affecting the endometrium. The use of letrozole typically results in monofollicular growth and this reduces the effect of supraphysiological levels of estrogen on the endometrium and embryo. The purpose of this study is to compare a frozen-thawed embryo transfer in an artificial cycle with a letrozole-induced ovulatory cycle, specifically in PCOS patients. The primary outcome is early pregnancy loss.
Design and protocol of PCO fasting research: This study is a pilot prospective, single-blinded (to the health assessor), randomized controlled trial conducted at the In Vitro Fertilization ( IVF) center of the Department of Obstetrics & Gynecology, Kasr El-Ainy Hospital, Cairo University, Egypt, from October 2018 to September 2019, to determine the clinical effect of fasting on ICSI outcomes in PCOS patients. Ethical committee approval was obtained. The study will include 100 infertile patients with PCOS diagnosed according to Rotterdam criteria of PCOS and who are candidates for ICSI cycle. Women with diabetes, thyroid disorder or other endocrine dysfunctions, uterine abnormalities were excluded. All patients are informed about the study and consent is given by those who accept to participate. Careful history taking include infertility type, duration , cause, obstetric history, medical and surgical history and demographic distribution is taken. Full physical examination and 2 dimensional (2D) transvaginal sonography (TVS) are done on day 2 to 5 of menses to assess antral follicle count, uterus and adnexa . Body mass index (BMI) and waist/hip ratio (WHR) are calculated, Blood samples are taken for Fasting insulin , fasting plasma glucose, Homeostatic model assessment (HOMA index), lipid profile and hormonal profile are done. All 100 participants will be randomized withdrawing closed envelopes for each patient into group A and group B . Group (A): patients will have periodic fasting for 4 weeks prior to the treatment cycle. The fasting method involves daily fasts of 14-16hours and restrict eating to an 8-10 hour "eating window" as 2-3 or more meals of balanced diet. Group (B): no fasting, patients will have usual balanced diet as 3 meals and 2 snacks all over the day. Both groups should take adequate water and non calorie beverages intake daily (2-3 liters) Subjects are instructed to wait for spontaneous menses, or to be prescribed progestins orally (as Norethisterone 5mg) twice daily for 21 days starting from the fifth day of menses. Patients should continue taking oral metformin 500-1000 mg daily, until confirmation of pregnancy. The next visit is scheduled on day 2 of next cycle when transvaginal ultrasound is done to confirm that endometrial thickness <5mm, no ovarian cyst by ultrasound. Body mass index (BMI) and waist/hip ratio (WHR) are calculated. Blood samples are taken for Fasting insulin , fasting plasma glucose, Homeostatic model assessment (HOMA) index, lipid profile ( Triglycerides (TGs), total cholesterol, High density Lipoprotein (HDL), Low density Lipoprotein (LDL), free and total testosterone , Sex Hormone Binding Globulin (SHBG), Free Androgen index (FAI), AntiMullerian Hormone (AMH), Basal Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), Estradiol (E2),and then antagonist protocol is followed. Gonadotropins as Intramuscular (I.M.) injections of 150-300 (International units) I.U. of highly purified Human Menopausal Gonadotropins daily (Merional, 75 I.U. /vial, IBSA). and Urofollitropin or highly purified human follicle stimulating hormone(Fostimon®, 75 I.U. /vial, IBSA) are give in a ratio of 1:1.The dose is adjusted according to the age, BMI, Antral follicle count (AFC), serum levels of AMH, FSH and ovarian response. Fixed antagonist protocol is given and follow up until embryo transfer(ET). Quantitative ß- HCG in serum after is done after 14 days of embryo transfer.TVS is performed to detect clinical pregnancy at 6-7 weeks of gestation. Primary outcome is clinical pregnancy rate per cycle. Secondary outcomes include Body mass index (BMI) and waist/hip ratio (WHR), fasting insulin , fasting plasma glucose, Homeostatic model assessment (HOMA) index, lipid profile and other ICSI outcomes.
This is a prospective, randomized clinical trial to compare the Global commercial single step media to 1) G-TL (Vitrolife), 2) Weill Cornell's single step and sequential steps media, which all support human embryo development in the laboratory using the Vitrolife Time-Lapse system. The main goal of the study is to identify the best culture medium for optimal embryo development.
The goal of this study is to observe the impact of caloric intake on ovarian reserve as measured by anti-müllerian hormone (AMH) levels and antral follicles (AFC) visualized on ultrasound. It has been shown that obesity negatively impacts these markers, but research is lacking regarding the influence of nutrition and caloric intake on fertility. This would give the investigators information on how diet may impact ovarian reserve in patients seeking fertility treatment.
Periodontal diseases and dental caries are initiated by a pathogenic biofilm, in a susceptible host, affecting the tooth periodontium and hard tissues. Its possible association with many biologic systems has been studied. In this study, researchers investigated association between oral health and female infertility, and what is the biological rationale for such relationship.
In ART (assisted reproductive technology) cycles, embryos are transferred to a woman's uterus after in-vitro fertilization (IVF) in a laboratory. Usually, hormones (progesterone) are given to the patient after transferring the embryo, as a supplement, in order to mimic the natural hormones that would normally be secreted in an unassisted pregnancy. This study will identify whether additional gonadotropin-releasing hormone (GnRH-agonist) administration, a natural hormone secreted from the hypothalamus, will improve the clinical pregnancy and live birth rates when using IVF.
Hydrosalpinx (HX) has a detrimental effect on the rates of implantation, pregnancy, live delivery, and early pregnancy loss during in vitro fertilization (IVF). The effectiveness of radiological tubal blockage has not been compared with the standard treatment of laparoscopic salpingectomy in randomized trials. The investigators aim in this randomized trial to compare the live birth rate of radiological tubal blockage versus laparoscopic salpingectomy in infertility women with HX prior to frozen-thawed embryo transfer (FET). Eligible women will be recruited and randomized into one of the following two groups: (1) the radiological tubal blockage group and (2) the laparoscopic salpingectomy group. The primary outcome is the live birth rate.
