Effect of body mass index and age on in vitro fertilization in polycystic ovary syndrome

“…(J Turk Ger Gynecol Assoc 2016; 17: 83-90) Keywords: PCOS, body mass index, age, IVF outcome Received: 31 December, 2015 Accepted: 8 March, 2016 Effect of body mass index and age on in vitro fertilization in polycystic ovary syndrome Bailey et al (12) investigated the effect of BMI on the characteristics and outcomes of IVF cycles in PCOS and found lower clinical pregnancy rates in an obese PCOS group than in a lean group and a lower rate of ovarian hyperstimulation syndrome (OHSS) in the obese group. A woman's age is also an important factor in IVF success (13,14). The IVF success rate reduces with increasing age in PCOS, as in all infertile patient groups (15, 16).…”

Total number of oocytes and zygotes are predictive of live birth pregnancy in fresh donor oocyte in vitro fertilization cycles

“…Factors that have been reported to predict LB outcomes for autologous cycles include age, body mass index (BMI), ethnicity, antral follicle count (AFC), previous live birth, previous miscarriage, and cause and duration of infertility (2). However, it is unclear if similar associations are present in donor oocyte IVF cycles, since oocyte donors have different baseline characteristics compared to infertile women seeking IVF with autologous oocytes.…”

Freezing eggs to get ahead: a look at oocyte cryopreservation for non-medical reasons

“…The procedure is even partially covered by the Ontario and Quebec provincial governments, and the federal government also supports its use with a 15% tax break for associated costs [8,9]. However, at the moment it does not guarantee success; only around half of the couples that begin treatment succeed in giving birth to a child [10]. The factors affecting fertility are still largely a mystery, and there are ongoing studies to refine the procedure, or attempt to predict the IVF outcome based on factors such as cause and duration of infertility, ethnicity, and so on [10].…”

“…However, at the moment it does not guarantee success; only around half of the couples that begin treatment succeed in giving birth to a child [10]. The factors affecting fertility are still largely a mystery, and there are ongoing studies to refine the procedure, or attempt to predict the IVF outcome based on factors such as cause and duration of infertility, ethnicity, and so on [10]. One clear conclusion from these studies is that maternal age and therefore oocyte age is a major factor affecting the success of IVF treatment.…”
