In a nutshell This study compared human menopausal gonadotropin (hMG) to follicle-stimulating hormone (FSH) prior to intracytoplasmic sperm injection (ICSI) for patients predicted to have a strong ovarian response. It found that both types of gonadotropin hormone were effective, but that hMG had fewer side effects and miscarriages. Some background...

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 examined if sperm quality affected the results of in vitro fertilization (IVF) in couples experiencing infertility. The results showed that higher sperm quality increased the chance of IVF success if few eggs were harvested. Some background IVF is a procedure where an egg is fertilized by a sperm in a dish. In cases...

In a nutshell This study investigated if fetal congenital malformations (FCM) are linked to recurrent miscarriage (RMC). They found that FCM was more likely in women with a history of RMC and birth defects. Some background Recurrent miscarriage (RMC) is defined by 2 or more failed pregnancies. RMC can be caused by a number of issues....

In a nutshell This study compared sperm concentration and quality with intrauterine insemination (IUI) outcomes. It found that IUI outcomes were similar for couples with high and low sperm quality. Some background IUI is an infertility procedure in which sperm are injected directly into the uterus. IUI is often combined with ovarian...

In a nutshell This study looked at routine variations in timing during intracytoplasmic sperm injection (ICSI). It found that changes in timing may affect egg quality, but did not alter pregnancy outcomes. Some background ICSI is an infertility treatment in which a single sperm cell is injected into the oocyte (egg). ICSI is most commonly used for...

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 investigated if cardiovascular function (CVF) is altered by in vitro fertilization (IVF). They found that IVF may cause short-term changes to CVF in women. Some background In vitro fertilization (IVF) is used to treat infertility. The first step of IVF involves harvesting eggs. Women inject hormones to stimulate the...

In a nutshell This study looked at activating oocytes (eggs) with calcium ions prior to intracytoplasmic sperm injection (ICSI). It found that this treatment improves fertilization rates for couples with male infertility, and may improve pregnancy rates. Some background ICSI is an infertility treatment used when there are few sperm available. It...

In a nutshell This study investigated if slow release (SR) intrauterine insemination (IUI) improves pregnancy rates in women with infertility. They found that SR-IUI may improve pregnancy rates in women under 35 years of age. Some background Infertility affects many couples. Assisted reproductive techniques (ART) can be used to achieve a pregnancy....

In a nutshell This analysis looked at the risk of miscarriage with increasing paternal age. It found that pregnancies by fathers over age 40 had a higher risk of miscarriage. Some background Miscarriages are unfortunately common, with over 10% of recognized pregnancies and an estimated 30% of all pregnancies ending in miscarriage. In 50 to 70% of...

In a nutshell This study investigated if body mass index (BMI; a measurement of weight in relation to height) is associated with newborn outcomes (NOs) in women with endometrosis (EDM). They found that underweight women had higher rates of preterm birth (PTB). Some background Endometriosis (EDM) is a condition where uterine tissue...
