The effect of cigarette smoking on ovarian reserve as measured by basal serum follicle stimulating hormone (FSH) concentrations, and by the response to a standard ovarian stimulation protocol, was examined retrospectively in 173 consecutive women (108 non-smokers and 65 smokers) undergoing in-vitro fertilization (IVF) and embryo transfer treatment. Women who smoked had a higher mean basal serum...

STUDY QUESTION Does maternal ageing and ovarian stimulation alter mitochondrial DNA (mtDNA) copy number and gene expression of oocytes and cumulus cells from a novel bovine model for human IVF? SUMMARY ANSWER Oocytes collected from females with identical nuclear genetics show decreased mtDNA copy number and increased expression of an endoplasmic reticulum (ER) stress gene with repect to ovari...

This study reports a case of a gonadotropin-releasing hormone agonist trigger in a young female with myelodysplastic syndrome (MDS) who underwent fertility preservation using random-start controlled ovarian stimulation. This method involves the stimulation of the ovary regardless of a patient's menstrual-cycle phase. A review of the related literature is also provided. A 17-year-old patient was...

the aim of this study was to evaluate the outcomes of adding low-dose hcg (human chorionic gonadotropin), as an lh active supplement, to a gnrh antagonist protocol in patients undergoing assisted reproduction techniques. in this parallel-group randomized clinical trial, 137 infertile female outpatients aged 20 - 39 years were randomized into two groups: hcg group and non-hcg group. all patients...

background: ovulation induction and art may be a newly recognized cause of vascular thrombosis in unusual sites in otherwise healthy women. objective: to report a case of thrombosis in right carotid artery 2.5 months after ovarian stimulation for ivf-et. case report: a non pregnant 39-year-old woman without coagulation disorder and ovarian hyperstimulation syndrome (ohss). the patient underwent...

OBJECTIVE To determine the effect of FSH doses on intracytoplasmic sperm injection (ICSI) outcomes according to the age of the patient. METHODS Patients undergoing controlled ovarian stimulation (COS) for ICSI cycles in a university-affiliated in vitro fertilization center were split into age groups: ≤35 y.o. (n=1523); >35 and ≤38 y.o. (n=652); >38 and ≤40 y.o. (n=332); and >40 y.o. (n=370). ...
