BACKGROUND Premature ovarian failure (POF) remains a clinically challenging entity because in vitro fertilisation (IVF) with donor oocytes is currently the only treatment known to be effective. METHODS A 33 year-old nulligravid patient with a normal karyotype was diagnosed with POF; she had a history of failed fertility treatments and had an elevated serum FSH (42 mIU/ml). Oocytes donated by ...
Starting in 1970s as experimental procedures following numerous trial-and-error processes, assisted reproductive technologies (ART) have developed extensively through the past three decades. Following the successful birth of the first IVF baby, ART rapidly developed in both research and clinical practice during 1980s. Then after during1990s, IVF clinics, different ART methods and their success ...
BACKGROUND Recently, the use of granulocyte colony-stimulating factor (G-CSF) has been proposed to improve pregnancy outcomes in reproductive medicine. OBJECTIVE A systematic review of the current use of G-CSF in patients who have difficulty conceiving and maintaining pregnancy was performed. MATERIALS AND METHODS Two electronic databases (PubMed/ Medline and Scopus) were searched. Study se...
This is a report of a case of an egg recovery procedure completed with manual suction instead of the automated negative pressure suction. A 35-year-old woman who was undergoing in vitro fertilization (IVF) treatment had to undergo oocyte recovery using manual suction through a syringe instead of the automated negative pressure suction systems because of the failure of both the initial and repla...

This prospective study was undertaken to reassess the prognostic value of leptin during critical stages of in vitro fertilization-embryo transfer (IVF-ET) and address its role in the functional staging of assisted reproductive technologies at the level of embryo quality. Serum and follicular fluid samples of 100 selected women undergoing the long IVF-ET protocol were collected for leptin and em...
While the role of inherited thrombophilia has been accepted as a cause of recurrent late pregnancy complications, the contribution of mutated thrombophilic genes to implantation failure has not been studied. Proteins involved in fibrinolysis are necessary for trophoblast invasion into the endometrium. This study compared the prevalence of 10 thrombophilic gene mutations among 42 women with a hi...
