In a nutshell This study looked at how diet relates to sperm quality. It found that men who eat soy are less likely to have low sperm count, and that men who include milk in their diets have better sperm quality. Some background In roughly half of the heterosexual couples experiencing infertility, the male partner has low sperm count or quality....

In a nutshell This study investigated the number of mature oocytes (eggs) needed to produce top-quality embryos (TQE). They found that at least 3 mature oocytes produced are associated with at least 1 TQE. Some background In vitro fertilization (IVF) first requires oocytes (eggs). They are retrieved by controlled ovarian stimulation (COS)....

In a nutshell This study investigated if controlled ovarian stimulation (COS) and progesterone (P) supplementation affects the microbiota (microorganisms found in the human body) of the vagina and uterus (womb). They found that COS alters the vaginal and uterine microbiota (VUM). Some background The rate of infertility is increasing worldwide. Many...

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 investigated if a dual-trigger treatment (DTT) improves pregnancy outcomes in older women with diminished ovarian reserve (DOR). They found that DTT improved in vitro fertilization (IVF) outcomes in these women. Some background In vitro fertilization (IVF) is an assisted reproductive technique (ART). The first step of...

In a nutshell This study investigated if intralipid (IL) improves pregnancy outcomes after previous implantation failure (IF). They found that IL may improve pregnancy outcomes in these women. Some background Infertility is becoming increasingly common. Assisted reproduction (AR) is used to treat infertility. In vitro...

In a nutshell This study investigated the use of stress scales in measuring the association between stress and poor testis function (PTF). They found that perceived stress (PS) is associated with reduced PTF. Some background Male infertility is one of the leading causes of infertility for couples. Poor testis function (PTF) is becoming more...

We are surrounded by glass but most people don’t know the first thing about it. Glass is a strange substance: It is partly a solid and partly a liquid. What does this mean? The atoms of solids are packed close together. If they are crystalline, they are in regular, repeating patterns. The atoms in liquids are not in a regular pattern and move...

In a nutshell This study investigated if physical activity (PA) improves testosterone deficiency (TD). They found that men with adequate PA levels were less likely to have TD. Some background Testosterone deficiency (TD) is low levels of testosterone (male sex hormone). This can cause a number of symptoms. They include decreased...

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 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...

In a nutshell This study investigated if the long-term development of children is affected by the type of embryo transfer (ET). They found that there were similar outcomes with fresh (fr) and frozen (fz) ET. Some background Assisted reproduction (AR) is used to treat infertility. It has become more common in recent years. There are a number of...
