Filter by:To analyze the effect of pretreatment with dydrogesterone vs combined estradiol valerate and dydrogesterone on embryologic parameters, chemical and clinical pregnancy rates of ICSI in women with PCOS.
Purpose: To compare the effects of the density gradient centrifugation and microfluidic chip sperm preparation methods on embryo development in a study population with astheno-teratozoospermia. Materials and Methods: In this prospective study, the semen samples of the patients with astheno-teratozoospermia were divided into two groups for preparation with either the microfluidic or density gradient methods. Selected spermatozoa were used to fertilize the mature sibling oocytes. Semen parameters and embryo development on days 3 and 5 were assessed.
In patients with oligospermia in the ejaculate or previous ICSI failures if it concurs with high DNA fragmentation, it has been hypothesized that the use of sperm obtained from the testicle would improve the clinical results, since a source of damage to the spermatic DNA is post-testicular in its storage in the epididymis and thus could be avoided. The clinical information available so far is low, of low quality and all the studies present certain limitations susceptible to improvements in further investigations before giving a definitive answer to patients in these circumstances, about whether they should opt for testicular biopsy or for the use of semen in the ejaculate.The intention proposed in our project, is to demonstrate whether using testicular sperm, compared to those available in an ejaculate in these cases, offers a clinically and statistically significant increase in chromosomally normal embryos available that may lead to better reproductive performance of the cycles, in a design never before done, where half of a patient's oocytes are inseminated from ejaculated sperm and the other half from sperm obtained in the testicular biopsy.
A randomized clinical trial to evaluate the effect of cytokine supplementation in embryo culture medium with various protein concentrations aiming to evaluate the effects of cytokines (CYK) integration into the human in vitro culture medium with high and low human serum albumin (HSA) concentrations on live birth rates after intracytoplasmic sperm injection (ICSI).
The study is conducted to evaluate the sensitivity and specificity of non-invasive preimplantation genetic testing for aneuploidy (NiPGT-A) using cell free DNA into spent culture medium (SCM).
This multicentre randomized controlled trial will be done to evaluate a new strategy in IVF-ICSI practice that gives that priority to freeze for the embryos and goes to fresh embryo transfer only if at least one set of same quality embryos is available for cryopreservation.
The role of progesterone (P) supplementation in the luteal phase of in vitro fertilization (IVF) cycles is well established world-wide , but the influence of the luteal phase estradiol level on implantation is not clearly defined . There is a significant difference in estradiol levels between fertile and infertile cycles of fertile women who underwent donor insemination.
ES is a procedure used to help embryos to implant more successfully after In-Vitro Fertilization (IVF) , ICSI in patients who had failed cycles in spite of transfer of good quality embryos. New researches and evidence suggests that scratching the uterine endometrium causes a repair reaction in patients may increase embryo implantation rate . In spit of the optimum timing of scratching not finally determined, the usual timing to perform ES is approximately one week before starting IVF, ICSI treatment . our study aims to compare other time of scratching which is the scratching at retrieval time.

Introduction To get through the egg vestment and fertilize the oocyte, the spermatozoon uses its acrosomal enzymes. When Intracytoplasmic sperm microinjection (ICSI) is performed, the acrosomal enzymes are introduced with the spermatozoa inside the ooplasme. The fate of these enzymes, that normally never enter the oocyte, is not known. But they impair the embryo development. Indeed, although the ICSI outcome is satisfactory in humans, a series of studies in many species (mouse, hamster, cattle, and horse) demonstrate the deleterious effects of the introduction of acrosomal material in the oocyte cytoplasm, on embryo and fetal development. These studies have also shown two things: - The bigger the acrosome, the more deleterious are the effects of their introduction into the egg. - And that the induction of the acrosome reaction (AR) prior to ICSI significantly improves embryonic development and the number of babies born after embryo transfer as it is the case in the mouse. The microinjection of acrosome reacted sperm increases from 40 to 70 % the percentage of pups born per embryo transferred. Hypothesis : It is possible to improve ICSI outcome, in terms of babies born in human, by induction of the AR prior to microinjection. After studying several techniques, we choose a physiologic technique for acrosome induction. The induction of acrosome reaction prior to ICSI should improve in utero fetal development and decrease the rate of miscarriage and pregnancy arrest.
