Filter by:This study aims to demonstrate a reliable method of selecting gender specific sperm. X-bearing spermatozoa and Y-bearing spermatozoa will be identified from the density gradient layers. The selected gender specimen will then be utilized for assisted reproductive fertilization- in vitro fertilization or intrauterine insemination which are routine standard of care procedures.
This is a multicenter, randomised controlled trial. The investigators plan to randomise 836 participants to the immediate FET or the postponed FET from the day of oocyte retrieval to the last day of that menstrual cycle in a 1:1 rate. Primary outcome will be the live birth rate after the embryo transfer.
Thanks to recent advances in clinical practice and laboratory, embryo cryopreservation has become the first-line procedure in assisted reproductive technology. Improved laboratory techniques have increased the number of available embryos derived from an in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycle. Implementation of a single embryo transfer policy to improve vitrification, improve postwarm embryo survival rates, and reduce multiple pregnancies without reducing cumulative birth rates has contributed to an increase in the number of frozen-warms (1,2) Embryo freezing; It is becoming an adopted practice for an increasing number of indications, including prevention of ovarian hyperstimulation syndrome, preimplantation genetic testing (PGT), late follicular phase progesterone elevation, and embryo-endometrial asynchrony. In our study, we are investigating the effect of pre-transfer serum progesterone levels on pregnancy outcomes in patients who underwent frozen-thawed embryo transfer.Supplementary progesterone preparations can be used to prevent luteal phase defect and to provide progesterone support in cycle preparations for frozen-thawed embryo transfer(3). The aim in this study is to show the effect of serum progesterone level on the pregnancy results on the day of embryo transfer in natural cycles.
This study is a comparison between the current standard practice of performing a transvaginal oocyte retrieval (TVOR) with paracervical block (PCB) and a relatively recently developed technology of virtual reality that is added to the above mentioned standard practice of TVOR + PCB. The aim of the study is to find out whether this newer technology has an advantage for the patient, in terms of anxiety and pain reduction or satisfaction.
The investigators propose a pilot study to determine if autologous platelet-rich plasma (PRP) improves ovarian reserves and In-vitro fertilisation (IVF) outcomes in women with diminished ovarian reserve / premature ovarian insufficiency.
Aim: A Clinical trial to determine the effectiveness of using the proposed decision support tool (OPTIVF) for each patient's customized optimal drug dosage profile. This will be a two-arm (in the ratio 1:3) clinical trial involving more than 80 participants; one arm will undergo superovulation using dosages predicted by the decision support tool while the other arm has undergone current standard treatment. The investigators will compare the outcomes of the two groups of participants in terms of the numbers and percentage of mature follicles retrieved at the end of each cycle, total FSH and HMG dosages used, and the number of required testing days for that cycle. The participants considered will include all ages, with and without PCOS, and low, average, and high responders.
Infertility is a disease that seriously affects the physical and mental health of women of childbearing age. The incidence of infertility has been increasing in recent years. Studies have shown that the occurrence of infertility may be related to environmental endocrine disrupting substances. This project was designed to establish a cohort study on environmental endocrine disrupting substances and in vitro fertilization (IVF) treatment, collect blood, urine, semen, follicular fluid, granulosa cells, chorionic decidua biological specimens, and then follow up on the pregnancy outcomes. The concentration of disrupting substances was detected and then found the associations between environmental endocrine disrupting substances and female reproductive health.
The primary outcome of the study is to determine if a difference in terms of pregnancy rate exists between direct and afterload embryo transfer (ET) techniques. The secondary end points include the evaluation of the difficult transfer rates.
We aimed to investigate whether endometrial scratching could improve IVF outcomes by enhancing endometrial receptivity in patients with endometriosis.
This study aims to investigate the efficacy of 3 different trigggers used for final maturation in the second ovarian stimulation in double stimulation protocol (aGnRH and hCG-rec vs. aGnRH only vs. hCG-rec only). The main objective is to compare the number of all retrieved oocytes and mature oocytes in patients predicted to be low ovarian responders. This is a controlled randomized clinical study where 165 patients will be recruited.
