BACKGROUND: Women undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) who have a predicted poor ovarian response (POR) present a challenge for reproductive medicine specialists. Traditional Chinese medicine (TCM) is commonly used in China for such patients, in the belief that it will improve the ovarian response and ultimately increase pregnancy rates. However, there is a lack of high-quality evidence about the effect of TCM on improving ovarian response in such patients...

OBJECTIVE: Thromboelastography (TEG) is a viscoelastic test of hemostasis which allows measurement of the processes of clot initiation, propagation, stabilization, and dissolution in real time. In this study we aimed to evaluate the alterations in coagulation as measured by TEG during In Vitro Fertilization (IVF) stimulation cycles and to investigate whether final oocyte maturation with recombinant hCG (rhCG) versus GnRH agonist results in a different coagulation state. STUDY DESIGN: This is a prospective observational study which included fifty-three normogonadotrophic women...

Background: Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication, which can cause high morbidity and mortality. Use of gonadotropin releasing hormone (GnRH) agonist instead of human chorionic gonadotropin (hCG) in GnRH antagonist cycles causes luteinizing hormone surge by GnRH stimulation which reduces the risk of OHSS by reducing the total amount of gonadotropin; however, there is no possibility of transferring fresh embryos. Objective: The current study aimed to evaluate the effect of hCG along with GnRH agonist administration in the occurrence of OHSS and pregnancy rate in females undergoing in vitro fertilization...

REVIEW
Kira Lynn Marshall, Rocío Melissa Rivera
A societal preference of delaying maternal age at first childbirth has increased reliance on assisted reproductive technologies/therapies (ART) to conceive a child. Oocytes that have undergone physiologic aging (≥35 years for humans) are now commonly used for ART, yet evidence is building that suboptimal reproductive environments associated with aging negatively affect oocyte competence and embryo development - although the mechanisms underlying these relationship are not yet well understood. Epigenetic programming of the oocyte occurs during its growth within a follicle, so the ovarian stimulation protocols that administer exogenous hormones, as part of the first step for all ART procedures, may prevent the gamete from establishing an appropriate epigenetic state...
