In a nutshell This study investigated fertility outcomes in women with polycystic ovarian syndrome (PCOS) who had a single ideal fresh embryo transfer. They found that the live birth rate (LBR) was lower in women with PCOS compared to control women. Some background Polycystic ovarian syndrome (PCOS) is a disorder that can cause infertility....

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...

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 compared gonadotropin-releasing hormone (GnRH) agonist versus GnRH antagonist protocols for stimulating the ovaries. It found that women under 30 years with high ovarian reserve benefited from the antagonist protocol, while the agonist protocol was better for women over 40 years or with low ovarian reserve. Some background...

In a nutshell This study investigated the risk of gestational diabetes (GD) with assisted reproductive technology (ART). They found that women that underwent ART had a higher risk of GD compared to spontaneous conception. Some background Assisted reproductive technology (ART) is used to treat infertility. In vitro fertilization (IVF) is an ART....

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...

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...

In a nutshell This study compared the use of follicle-stimulating hormone (FSH) with human chorionic gonadotropin (hCG) during egg preparation for in vitro fertilization (IVF). The results showed that hCG reduced the cost of IVF considerably and was as effective as FSH for egg preparation. Some background One of the major considerations for...

In a nutshell This analysis looked at whether granulocyte colony-stimulating growth factor (G-CSF) can improve in vitro fertilization (IVF) outcomes. This study found that G-CSF may improve pregnancy rates for women with two or more unsuccessful IVF cycles. Some background In vitro fertilization (IVF) is an infertility treatment where eggs...

In a nutshell This study looked at whether blood levels of the HCG hormone affect the chances of pregnancy after in vitro fertilization (IVF). This study concluded that having high HCG levels in the blood was associated with a higher chance of pregnancy. Some background IVF is an infertility treatment in which eggs are removed from a...

In a nutshell This study looked at rates of birth defects among infants of women with endometriosis who conceive through IVF (in vitro fertilization). This study found that these infants may be at higher risk of birth defects. Some background Endometriosis (EM) is a disease where cells from the uterus grow in other areas of the body, such as in the...

In a nutshell This study investigated if bed rest after embryo transfer (ET) improves fertility outcomes. They found that bed rest after ET did not affect clinical pregnancy (CP) and live birth rate (LBR). Some background Embryo transfer (ET) is the final step of assisted reproduction. Embryos are formed in a laboratory using in vitro...
