In a nutshell This study looked at the number of days of progesterone treatment before frozen embryo transfer (FET) in hormone replacement cycles. It found that transfers after 7 days of progesterone may miscarry less, but the birth rate was the same as transfers after 6 days of progesterone. Some background In vitro fertilization (IVF) is an...Read More

In a nutshell This study investigated using anti-Mullerian hormone (AMH; Elecsys) and antral follicle count (AFC) to predict the response to ovarian stimulation (OS) with corifollitropin alfa (CFA; Elonva). It found that these tests give good predictions of both high and low ovarian response. Some background OS uses medications, particularly...Read More
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...Read More
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...Read More
Does physical activity and sedentary behavior affect pregnancy outcomes after assisted reproduction?
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...Read More
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...Read More
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...Read More
In a nutshell This study compared in vitro maturation (IVM) to double ovarian stimulation (DuoStim) for women expected to have a poor outcome from in vitro fertilization (IVF). It found that both methods increased the number of eggs compared to standard IVF, and that DuoStim may be more effective. Some background The first step of the infertility...Read More
Does they type of insemination have an effect on reproductive outcomes in women with PCOS using in vitro maturation?
In a nutshell This study compared traditional in vitro fertilization (IVF) to intracytoplasmic sperm injection (ICSI) for in vitro maturation of eggs. It found that both insemination methods led to good fertilization and pregnancy outcomes for patients with polycystic ovarian syndrome (PCOS). Some background PCOS is a condition in which a woman has...Read More
In a nutshell This study looked at using home urine tests of luteinizing hormone (LH) prior to egg collection. It found that home LH tests were a convenient, cost-saving, and effective method to confirm the final egg maturation prior to collection. Some background Egg collection is an infertility procedure which is used prior to egg donation or in...Read More
In a nutshell This study compared mild ovarian stimulation (OS) to conventional OS for women with a poor ovarian response (POR) who were undergoing in vitro fertilization (IVF). It found that conventional OS resulted in more embryos, but the live birth rate after IVF was the same for both types of stimulation. Some background IVF is an...Read More
In a nutshell This study looked at whether body weight in women affects the outcomes of in vitro fertilization (IVF). It found that women of normal weight had higher birth rates than women who were underweight or obese. Some background Weight affects many aspects of the body, including fertility. Women who are underweight may stop ovulating. Obesity...Read More
