A slow freezing/rapid thawing method for the cryopreservation of human oocytes has been employed using a sodium-depleted culture media. In 53 frozen egg-embryo transfer (FEET) cycles, a 60.4% survival rate post-thaw was obtained and a 62.0% fertilization rate following intracytoplasmic sperm injection. Overall pregnancy rates were 26.4% per thaw attempt, 30.4% per patient, and 32.6% per embryo ...

OBJECTIVE To review utilisation of elective embryo cryopreservation in the expectant management of patients at risk for developing ovarian hyperstimulation syndrome (OHSS), and report on reproductive outcome following transfer of thawed embryos. MATERIALS AND METHODS Medical records were reviewed for patients undergoing IVF from 2000-2008 to identify cases at risk for OHSS where cryopreservat...

background: successful embryo transfer (et) technique is a fateful step of all efforts to achieve live births from in vitro produced embryos in assisted reproductive techniques or in knockout, transgenic or cloned animal projects. small reproductive tract of mice and limitation of current techniques may not well satisfy the requirements for mass production of genetically modified mice. genetic ...

To investigate how estrogen level on the endometrial transformation day for hormone replacement therapy-frozen-thawed embryo transfer cycle influences pregnancy outcome. A retrospective analysis was conducted clinical data from 772 patients who underwent therapy-frozenthawed between January 2016 and 2020 in Reproductive Medicine Center, Maternal Child Health Hospital of Shaoguan City. The were ...

BACKGROUND In couples presenting with retrograde ejaculation refractory to medical treatment, the first choice of fertility treatment should be Assisted Reproductive Techniques using rapidly purified spermatozoa retrieved from post-ejaculatory urine. The Hotchkiss technique and modified variants are simple and efficient for retrieving sperm from the bladder. We developed a new protocol, includi...

In-vitro fertilization patients (n = 15) at risk of ovarian hyperstimulation syndrome (OHSS) (oestradiol > or =4500 pg/ml on the day of human chorionic gonadotrophin administration and 25 or more follicles of intermediate or large size) underwent aspiration of all follicles and cryopreservation of all fertilized oocytes at the pronuclear stage. Patients were monitored for up to 2 weeks post-ret...

The aim of this study was to determine the efficacy in- vitro fertilization, and embryo transfer (IVF-ET) in patients with hyper-response Ovarian Stimulation for intrauterine insemination (IUI). A Retrospective study, conducted Ferty9 Fertility Center. Rescue IVF-ET offered forty seven IUI cycles having excessive follicular development patient consent. Patients were counseled IVF conversion whe...

The freeze-all strategy has emerged as an alternative to fresh embryo transfer (ET) during in vitro fertilization (IVF) cycles. Although fresh ET is the norm during assisted reproductive therapies (ART), there are many concerns about the possible adverse effects of controlled ovarian stimulation (COS) over the endometrium. The supra-physiologic hormonal levels that occur during a conventional C...

BACKGROUND The purpose of this study was to determine the optimal endometrial preparation protocol by comparing the clinical outcome of two methods of endometrial preparation in frozen-thawed embryo transfer (FET) cycles, including that is, oral estradiol and 17ß-estradiol transdermal patch. METHODS In this randomized controlled trial, women underwent either conventional IVF or intracytoplasm...
