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 study looked at whether womb lining thickness and embryo quality affect the natural cycle during in vitro fertilization (NC-IVF). It found that thicker womb linings and better quality embryos were related to higher pregnancy rates. Some background IVF is an infertility treatment in which eggs (oocytes) are removed from a...

In a nutshell This study looked at whether embryo transfer on day 3 or day 4 to 5 was better for patients undergoing IVF (in vitro fertilization). This study found that day 3 transfer led to better outcomes compared to transfer on a later day. Some background In vitro fertilization (IVF) is an infertility treatment in which eggs are removed from a...

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 whether injecting HCG hormone into the womb before embryo transfer improved pregnancy rates. This study concluded that HCG improved pregnancy rates for women with a history of unsuccessful implantation. Some background One cause of infertility is poor implantation of an embryo in the uterus. This occurs when the...

In a nutshell This study compared women who had an ectopic pregnancy (EP) vs a normal pregnancy following in vitro fertilization (IVF). It found that a thick lining of the womb protects against EP, and pelvic surgery and tubal-related infertility are risk factors for EP. Some background Ectopic pregnancy (EP) is when an embryo implants somewhere other...

In a nutshell This study compared two types of IVF (in vitro fertilization) procedures for older women with a poor ovarian response. This study found that modified natural cycle IVF was promising, but not more effective than conventional IVF in older women with POR. Some background In vitro fertilization (IVF) is a method to treat...

In a nutshell This study investigated if there is an association between blastocyst number (BCN) and pregnancy outcomes. They found that a BCN of up to 5 was associated with positive pregnancy outcomes. Some background In vitro fertilization (IVF) is a technique used to fertilise an egg in a laboratory. The fertilized embryo is allowed to...

In a nutshell This study investigated if obesity is associated with fertility outcomes after in vitro fertilization (IVF). They found that obesity was associated with a lower live birth rate (LBR) after IVF. Some background The rate of obesity is increasing rapidly worldwide. Obesity can have a negative impact on overall health. It can also have a...

In a nutshell This study investigated the effects of an early gonadotrophin-releasing hormone (GnRH) protocol in women with polycystic ovarian syndrome (PCOS). They found that an early GnRH antagonist protocol may improve fertility outcome in women with PCOS. Some background Polycystic ovarian syndrome (PCOS) Is a common cause of female infertility....

In a nutshell This study investigated the success rates of in vitro fertilization (IVF) following either frozen or fresh embryo transfer. They found that frozen-thawed embryo transfer resulted in higher pregnancy and birth rates. Some background To treat infertility embryos are artificially fertilized using techniques such as in vitro...
