Effects of BPA on embryos in females undergoing IVF
Bisphenol A (BPA) is an industrial chemical that is used in a variety of consumer products, such as water bottles, metal food and beverage containers, and thermal paper cash register receipts. Long considered to have health effects on animals and humans, exposure to BPA may lead to reduced quality of embryos during reproduction. Fred vom Saal, a University of Missouri endocrinologist and researcher, has studied BPA and its effects on the reproductive system for more than 20 years. Now, a...

Using ultrasensitive protein detection method to evaluate embryo quality
Infertility is estimated to affect 9% of reproductive-aged couples globally, and many couples consequently turn to assisted reproductive technology (ART). Selecting embryos with maximum development potential plays a pivotal role in obtaining the highest rate of success in ART treatment, which ultimately determines whether a couple gets pregnant.
The conventional way to select embryos is based mainly on a morphological score, a score based on the form of the embryo. This method, however, is subjective, and there is inherent variability...

Study determines factors associated with oophorectomy in patients with ovarian torsion
Ovarian torsion can cause severe pain and other symptoms because the ovary is not receiving enough blood due to twisting of its blood supply. It can occur at any age and is responsible for nearly three percent of all gynecologic emergencies. An oophorectomy is performed when there is concern that the torsed ovary is nonviable (necrosis) based on its dusky color. However, numerous studies have shown that a surgeon's ability to determine necrosis based on physical appearance is inaccurate.

Study finds no developmental differences in children conceived via ART
Parents with children conceived via IVF, IUI or using infertility medication can rest assured that treatment has no impact on childhood development.
In a study from Fertility Centers of Illinois in collaboration with Rush University Medical Center, parents of children conceived spontaneously and through assisted reproductive technology (ART) reported developmental milestones from birth to five years old in the Ovia Parenting app. Developmental milestones were created using CDC guidelines.
Both groups achieved developmental milestones in a similar timeline. A significant...

Study highlights the importance of healthy placental development in pregnancy
The first stages of placental development take place days before the embryo starts to form in human pregnancies.
The finding highlights the importance of healthy placental development in pregnancy, and could lead to future improvements in fertility treatments such as IVF, and a better understanding of placental-related diseases in pregnancy.
In a study published in the journal Nature, researchers looked at the biological pathways active in human embryos during their first few days of development to understand how cells acquire different...

Study: Novel drug may treat reproductive health problems in women
A drug that acts via the natural 'kisspeptin' hormone system in the body has the potential to treat reproductive health problems in women, according to a new study.
Twenty-four women were injected with a drug called MVT-602 which targets the kisspeptin system to stimulate reproductive hormones that affect fertility, sexual development and menstruation.
The naturally occurring form of kisspeptin called kisspeptin-54 (KP54) has been researched for a number of years to treat reproductive disorders, but in the new study, MVT-602...

Women treated with fertilitysparing surgery for ovarian tumors could become pregnant
Women receiving fertilitysparing surgery for treatment of borderline ovarian tumors were able to have children, a study from Karolinska Institutet in Sweden published in Fertility & Sterility shows. Natural fertility was preserved in most of them and only a small proportion required assisted reproductive treatment such as in vitro fertilization. Survival in the group was also as high as in women who had undergone radical surgical for treatment of similar tumors.
"The ability to become pregnant seems to be preserved...

Doctors propose ways to reduce obstetrical complications in women with endometriosis
A team of doctors from RUDN University with their Italian colleagues had studied the data of existing studies on the effect of endometriosis on pregnancy and childbirth and suggested ways to reduce obstetrical complications in women with this condition. The results of the work were published in The Journal of Maternal-Fetal&Neonatal Medicine.
Edometriosis is a pathological process accompanied by growth of benign of tissues (that are morphologically and functionally similar to endometrium) outside the uterine cavity. In the premenstrual...
