Researchers reach milestone in developing non-hormonal approach to male contraception

Researchers studying strategies to develop a non-hormonal approach to male contraception have reached an important milestone in their work, discovering a way to produce a key enzyme found only in sperm in sufficient quantities that they can begin designing drugs to stop the sperm from swimming to the egg.

Study finds no difference in outcomes for children raised by same-sex parents

Children raised by same-sex female parents with a stable family life show no difference in general health, emotional difficulties, coping and learning behavior, compared to children of different-sex parents in similarly stable relationships, concludes a study in the April Journal of Developmental & Behavioral Pediatrics, the official journal of the Society for Developmental and Behavioral Pediatrics. The journal is published by Wolters Kluwer.

Research looks at effects of traumatic childbirth on midwives and obstetricians

When complications arise in the delivery room that lead to traumatic childbirth, clinicians providing care may feel upset and experience secondary traumatic stress.

Maternal obesity, poor nutrition during pregnancy affect egg reserves of female child

New research involving mice, published in the April 2016 issue of The FASEB Journal, suggests that maternal obesity and poor nutrition during pregnancy affects the egg reserves of female offspring. This discovery improves scientific understanding of the long-term, generational, effects of obesity and poor nutrition. This understanding is the first step toward devising interventions to protect the fertility of females who experienced very difficult womb environments.

Traumatic childbirth may impact healthcare professionals' mental health

When complications arise in the delivery room that lead to traumatic childbirth, clinicians providing care may feel upset and experience secondary traumatic stress. A new study published in Acta Obstetricia et Gynecologica Scandinavica, a journal of the Nordic Federation of Societies of Obstetrics and Gynecology, found that feelings of blame and guilt dominate when midwives and obstetricians struggle to cope with the aftermath of a traumatic childbirth, but such events also made them think more about the meaning of life and helped them become better midwives and doctors.

Infant daughters may show early signs of PCOS from mothers

The infant daughters of women with polycystic ovary syndrome (PCOS) show a higher level of an enzyme that activates testosterone and may be an early sign of developing the complex genetic disease, according to a new Northwestern Medicine study.

Breast cancer medication letrozole could increase ovulation in women with PCOS

A medicine used in breast cancer treatment is now considered the best option for treating the most common cause of infertility.

Fertility 'reassurance' for most chemotherapy-treated female childhood cancer survivors

Both female and male chemotherapy-treated survivors of childhood cancer have an increased risk of impaired fertility, but results suggest that the risk in women is limited to those given specific chemotherapy drugs.

Putative male-determining gene discovery could help develop strategies to combat malaria

A group of scientists, including one from the University of California, Riverside, have discovered a long-hypothesized male determining gene in the mosquito species that carries malaria, laying the groundwork for the development of strategies that could help control the disease.

Researchers use novel technology to sequence Y chromosome in malaria spreading mosquitoes

A team of researchers with the Fralin Life Science Institute at Virginia Tech, working with a large international consortium, has sequenced the Y chromosome--the genetic driver of sex-determination and male fertility-- in a family of malaria spreading mosquitoes.

Fertility goes down when cost of achieving social status goes up

Competition for social status may be an important driver of lower fertility in the modern world, suggests a new study published in Philosophical Transactions of the Royal Society B.

Couple's caffeinated beverage consumption can increase risk of miscarriage

A woman is more likely to miscarry if she and her partner drink more than two caffeinated beverages a day during the weeks leading up to conception, according to a new study from researchers at the National Institutes of Health and Ohio State University, Columbus.

Women who have survived childhood cancer can become pregnant, shows study

For women who have survived childhood cancer, the impact of modern chemotherapy regimens on the likelihood of becoming pregnant is generally small, and most have a good chance of conceiving, according to one of the largest studies of its kind published in The Lancet Oncology.

Female childhood cancer survivors have a good chance of conceiving

A new study examines fertility issues in male and female childhood cancer survivors who had received chemotherapy. The study found that while most female survivors still have a good chance of conceiving, male survivors are significantly less likely to father children.

Mothers give offspring a head start in life

Thank your mothers: A research collaboration between UC Santa Barbara and L'École Normale Supérieure in Paris has proven that deterministic maternal effects can give offspring a better start on life.

Postnatal depression dissuades women from having a third child

Mothers who have postnatal depression are unlikely to have more than two children according to research carried out by evolutionary anthropologists the University of Kent and published by Evolution, Medicine and Public Health.

Researchers aim to design a better male contraceptive pill

Women can choose from a wide selection of birth control methods, including numerous oral contraceptives, but there's never been an analogous pill for men. That's not for lack of trying: For many years, scientists have attempted to formulate a male pill. Finally, a group of researchers has taken a step toward that goal by tweaking some experimental compounds that show promise.

Biological change in mosquito mating could be used to fight mosquito-borne diseases

Genetic cues from male Aedes aegypti mosquitoes passed on during sex affect which genes are turned on or off in a females' reproductive tract post-mating, including genes related to blood feeding, egg development and immune defense, according to new Cornell research.

Fertility problems put men at increased risk of metabolic diseases

Men with fertility problems are at risk of metabolic diseases as they age, according to work being presented at the European Association of Urology conference in Munich

New study assesses link between depression, anxiety and antidepressants and outcome of IVF

Depression and anxiety, and not necessarily the use of antidepressant medication, are associated with lower pregnancy and live birth rates following in vitro fertilisation, according to a large register study from Karolinska Institutet in Sweden. The findings are published in the journal Fertility & Sterility and can be of interest to clinicians treating infertility and for women with depression or anxiety planning to undergo fertility treatment.
