In a nutshell This study investigated if preimplantation genetic testing (PGT) improves live birth rates (LBR) with donor oocytes. They found that frozen embryo transfer (fzET) cycles with PGT had higher LBR. Some background Preimplantation genetic testing (PGT) is a technique used on embryos. It can determine if there are any abnormalities...

In a nutshell This study looked at how bodyweight affected ectopic pregnancy (EP) in women undergoing in vitro fertilization (IVF). It found that women with a low body weight have a higher rate of EP. Some background An ectopic pregnancy (EP) occurs when an embryo implants somewhere other than in the uterus. It occurs most often in the Fallopian...

In a nutshell This study investigated if the follicle-stimulating hormone (FSH) dose is associated with pregnancy outcomes during oocyte donation (OD). They found that higher FSH doses were associated with reduced live birth rates (LBR). Some background Infertility is an increasing problem for couples. Assisted reproduction (AR)...

In a nutshell This study investigated if physical activity (PA) or sedentary behavior (SB) affect fertility outcomes in women undergoing assisted reproduction (AR). They found that PA and SB during AR did not affect fertility outcomes, while higher PA before AR was associated with higher ovarian response to stimulation. Some background...

In a nutshell This study investigated if ovarian response (OR) has an effect on pregnancy outcomes after embryo transfer (ET). They found that frozen ET (fzET) was associated with better pregnancy outcomes in women with high OR. Some background Assisted reproduction (AR) is used to treat infertility. It involves a number of steps. Controlled...

In a nutshell This study compared three methods of preparing the uterine lining prior to frozen embryo transfer (FET). It found that modified natural cycles may have higher pregnancy rates than either fully natural cycles or artificial hormone replacement. Some background FET involves transferring an embryo which was frozen after in vitro...

In a nutshell This study investigated laparoscopic ovarian drilling (LOD) compared to medical ovulation induction (MOI) in women with polycystic ovarian syndrome (PCOS). They found that LOD was associated with decreased live birth rates (LBR) when compared with MOI. Some background Polycystic ovarian syndrome (PCOS) is a common condition. It is...

In a nutshell This study investigated factors affecting fertility in women with endometriosis (EDM). They found that age and infertility time were associated with pregnancy rates in these women. Some background Endometriosis (EDM) is a common condition in women. EDM is caused by uterine tissue growing outside the womb. This can cause pain...

In a nutshell This study investigated if inhibin A (IHA) is associated with oocyte maturation (OM) during ovarian stimulation (OS). They found that IHA levels are associated with OM. Some background Infertility is an increasing problem worldwide. Assisted reproductive techniques (ART) are used to treat infertility. Controlled ovarian stimulation...

In a nutshell This study investigated a combined Stop GnRH agonist and multiple-dose GnRH antagonist protocol for patients with a previous poor ovarian response (POR). It found that this protocol may lead to a higher number of oocytes collected. Some background Patients with POR produce few oocytes (eggs) in response to ovarian stimulation (OS)...

In a nutshell This study compared modified natural cycle to stimulated cycle prior to the transfer of a frozen embryo. It found that birth rates were similar for both methods, although there was a trend toward increased early pregnancy loss with STC. Some background In vitro fertilization (IVF) is an infertility treatment which stimulates the ovaries...

In a nutshell This study looked at the effect of preimplantation genetic testing (PGT) on in vitro fertilization (IVF) outcomes for women with a poor ovarian response (POR). It found that PGT led to similar birth rates, but there were fewer miscarriages. Some background The first step of the infertility treatment IVF is to stimulate and collect...
