Researchers link RHOX gene mutations to infertility in men

Researchers link RHOX gene mutations to infertility in men

The underlying cause of male infertility is unknown for 30 percent of cases. In a pair of new studies, researchers at University of California San Diego School of Medicine determined that the reproductive homeobox (RHOX) family of transcription factors — regulatory proteins that activate some genes and inactivate others — drive the development of stem cells in the testes in mice.

High stress during ovulatory window reduces chances of conception in women

What many have long suspected, has been scientifically confirmed - women's high stress reduces their probability of conception. [More]
Women find men with full beards more attractive when judging long-term relationships, study shows

Women find men with full beards more attractive when judging long-term relationships, study shows

New research suggests that women tend to find beardedness attractive when judging long-term relationships, perhaps as a signal of formidability among males and the potential to provide direct benefits, such as enhanced fertility and survival, to females. [More]
Male signals trigger female animals for reproduction but with harmful effects

Male signals trigger female animals for reproduction but with harmful effects

A research team led by a Northwestern University scientist has discovered that male animals, through their invisible chemical "essence," prime female animals for reproduction but with the unfortunate side effect of also hastening females' aging process. [More]
Measuring blood levels of newly identified hormone may improve diagnosis of PCOS in teenagers

Measuring blood levels of newly identified hormone may improve diagnosis of PCOS in teenagers

Measuring blood levels of the recently discovered hormone irisin may improve diagnosis rates of teenagers with polycystic ovary syndrome, according to research presented today at the 55th Annual European Society for Paediatric Endocrinology Meeting. [More]
Steroids for treating infertility in women may have harmful effects on pregnancy and child

Steroids for treating infertility in women may have harmful effects on pregnancy and child

Researchers at the University of Adelaide are urging doctors and patients to refrain from using a specific steroid treatment to treat infertility in women unless clinically indicated, because of its links to miscarriage, preterm birth and birth defects. [More]
UBC research reveals pregnancy rates of transgender youth similar to other young people

UBC research reveals pregnancy rates of transgender youth similar to other young people

Sexually active transgender youth have pregnancy rates similar to their non-transgender peers--dispelling the notion that trans youth are less at risk for pregnancy, according to new UBC research. [More]

New demographic datasheet provides comprehensive details on migration and aging

The European Demographic Datasheet 2016, produced by demographers at the International Institute for Applied Systems Analysis and the Vienna Institute of Demography, provides a comprehensive look at key demographic indicators and main population trends for all European countries, including population projections for 2050.

New study reveals physicians not discouraging Egyptian women from practicing female circumcision

New study reveals physicians not discouraging Egyptian women from practicing female circumcision

Women in Egypt are seeking out doctors' opinions on whether they should circumcise their daughters and, though it is illegal there, physicians are not discouraging the practice, giving legitimacy to a procedure that has serious medical risks, according to a new study led by a former Stanford University School of Medicine researcher.

Developmental exposure to fracking chemicals may pose threat to fertility

Developmental exposure to fracking chemicals may pose threat to fertility

More than 15 million Americans live within a one-mile radius of unconventional oil and gas operations. UOGs combine directional drilling and hydraulic fracturing, or "fracking," to release natural gas from underground rock. [More]
Preimplantation genetic screening using next generation sequencing: an interview with Dr Luis Alcaraz

Preimplantation genetic screening using next generation sequencing: an interview with Dr Luis Alcaraz

PGS, Preimplantation Genetic Screening, is a genetic test that analyses biopsied cells from embryos produced by in vitro fertilization (IVF) techniques. PGS determines whether the embryos are chromosomally normal (euploid) or not (aneuploid), thus giving the chance to transfer chromosomally normal embryos that are more apt to successfully implant and develop into a pregnancy.

Scientists discover less invasive, cheaper technique to improve woman's chances of becoming pregnant

Scientists discover less invasive, cheaper technique to improve woman's chances of becoming pregnant

For those facing infertility, IVF has long been the established option to have a baby. Now Australian and Belgian medical scientists have discovered how to improve a woman's chances of becoming pregnant using a less invasive and cheaper alternative. [More]
Molecular alarm clock awakens ovules from resting period

Molecular alarm clock awakens ovules from resting period

At the start of reproductive life an ovary contains, on average, several thousands of immature ovules in a resting state that can last for several decades. [More]
Study finds potential gap in access to fertility services by LGBT persons

Study finds potential gap in access to fertility services by LGBT persons

With the recent one-year anniversary of Obergefell vs Hodges--the landmark U.S. Supreme Court decision legalizing same-sex marriage--researchers at Boston University School of Medicine have published a report that identifies unequal online availability of educational materials regarding assisted reproductive technology (ART).

UCLA study suggests lower BPS doses damage woman's egg cells

UCLA study suggests lower BPS doses damage woman's egg cells

Bisphenol S, a chemical used to manufacture polycarbonate water bottles and many other products such as epoxy glues and cash receipts, is an increasingly common replacement for bisphenol A, the of which was discontinued because of concerns about its harmful effects on the reproductive system.

Reproductive age-related changes in ovarian environment may contribute to infertility

Reproductive age-related changes in ovarian environment may contribute to infertility

Women's decreased ability to produce healthy eggs as they become older may be due to excessive scarring and inflammation in their ovaries, reports a new Northwestern Medicine study in mice. [More]
New study shows some Catholic hospitals actively discourage referrals for reproductive services

New study shows some Catholic hospitals actively discourage referrals for reproductive services

Catholic hospitals, which represent a growing share of health care in the United States, prohibit staff from providing many common reproductive health services, including ones related to sterilization, contraception, abortion, and fertility. [More]

Scientists test endometrial scratching technique in first-time IVF attempters

A NEW simple procedure which involves gently scratching the lining of the womb in the month before IVF treatment, potentially improving treatment success, is being tested on first-time IVF attempters in a groundbreaking study. [More]
Biologists discover male-harming mtDNA mutant that substantiates mother's curse hypothesis

Biologists discover male-harming mtDNA mutant that substantiates mother's curse hypothesis

There is new evidence that the "mother's curse" - the possibility that moms may transmit genes to their children that harm their sons but not their daughters - holds true in animals. [More]
