Infertility primarily refers to the biological inability of a person to contribute to conception. Infertility may also refer to the state of a woman who is unable to carry a pregnancy to full term.

Methoxychlor (MXC), a common insect pesticide may lead to reduced fertility in women

Methoxychlor (MXC), a common insect pesticide used on food crops, may interfere with proper development and function of the reproductive tract, leading to reduced fertility in women, researchers at Yale School of Medicine write in the August issue of Endocrinology.

Workshop - stem cells in reproduction and in the brain

"Once we have found the factors by which body cells can be re-programmed into stem cells, then therapeutic cloning might become superfluous," said Hans R. Scholer, director of the Max Planck Institute for Molecular Biomedicine in Munster, Germany, at an international scientific symposium on stem cell research in Kobe, Japan.

Methoxychlor (MXC) may interfere with proper development and function of the reproductive tract, leading to reduced fertility in women

The researchers found that MXC, which was manufactured as a safer replacement for the now-banned DDT, alters the estrogen-regulated gene Hoxa10 in the reproductive tract and reduces the ability of the uterus to support embryo implantation. The researchers used mice and then human cell lines to confirm their findings.

Recent evidence suggests caution in prescribing hormone therapy for breast cancer

One of the most effective new treatments for breast cancer is a hormone therapy. Aromatase inhibitors work by powerfully blocking the conversion of androgen precursors into estrogens, which lowers estradiol levels in the bloodstream and estrogen levels in peripheral tissues.

Sperm testing in UK labs fails to meet World Health Organization standards

Teams from the Universities of Bristol and Sheffield found only five per cent of the clinics met all WHO standards for assessing the size and shape of sperm.

How germ cells decide whether to be sperm or eggs

Johns Hopkins biologists have determined how developing embryos tell their specialized "germ cells" whether to develop into a male's sperm or a female's eggs.

Long-term hormone therapy used earlier in menopause is associated with fewer wrinkles

Long-term hormone therapy used earlier in menopause is associated with fewer wrinkles and less skin rigidity in postmenopausal women, Yale School of Medicine researchers report in the August issue of Fertility and Sterility.

Stress does not appear to influence the outcome of IVF

New research from Sweden has shown that psychological stress does not appear to influence the outcome of IVF – good news for women who fear that the understandable anxiety that they suffer during fertility treatment might damage their chances of conceiving.

Young breast cancer sufferers need more fertility advice before treatment

According to new research led by the University of New South Wales (UNSW), Australia, 25% of young breast cancer sufferers say that there was no discussion of fertility issues at the time of diagnosis, despite the possibility of infertility after treatment.

Acupuncture may help some men overcome infertility

Researchers found five weeks of acupuncture treatment reduced the number of structural abnormalities in sperm and increased the overall number of normal sperm in a group of men with infertility problems.

MicroRNAs play an important role in regulating oogenesis

Researchers at Northwestern University and Carnegie Mellon University have found that a recently described class of molecules called microRNAs (miRNAs) play an important role in regulating oogenesis, the process by which females make eggs.

Link between peritoneum closure and fewer adhesions

A controversial surgical procedure that has lost favor among medical professionals may benefit women who have had caesarean sections. So say researchers at the Stanford University School of Medicine, who have found that closing the parietal peritoneum, a multi-layered membrane that lines the abdomino-pelvic walls, substantially decreases the likelihood of scarring that can make future C-sections more difficult.

Researchers find that female circumcision could cause infertility

Swedish researchers, say the practice of female circumcision, which is practised in more than 30 countries and affects 2 million girls each year, could cause infertility.

Bone marrow may be source of new egg-cell generation

Last year a group of Massachusetts General Hospital (MGH) researchers announced surprising findings that female mice - contrary to longstanding theories of mammalian reproductive physiology - retained the ability to make new egg cells or oocytes into adulthood.

Condom-use errors are associated with gonorrhea infection in men

Condom-use errors are associated with gonorrhea infection in men, according to a recent study of patients at a clinic specializing in sexually transmitted diseases. The finding highlights the importance of promoting not only consistent condom usage, but also correct usage.

One shot testicular cancer drug as good as radiotherapy

A single dose of the drug carboplatin is as effective at treating testicular cancer as two to three weeks of radiotherapy.

Fertility boost for testicular cancer patients

The vast majority of men who try to have a family, following treatment for testicular cancer, are able to father children - according to a report published today in the British Journal of Cancer.

Fertility drugs may be ineffective for women who lack a gene called the estrogen receptor beta

"What we found is that the beta estrogen receptor plays a role in moving the egg outside the ovary so it can be fertilized," said Kenneth Korach, Ph.D., Laboratory Chief at the National Institute of Environmental Health Sciences (NIEHS) where the research was conducted. "We never knew before what function this receptor played in reproduction."

New molecular insights may one day lead to opportunities to stave off old age

Delving deep into the molecular subtleties of a strain of mice engineered to age rapidly, scientists have found that an accumulation of genetic mutations prompts a cascade of programmed cell death that seems to underpin the aging process.

Low dose birth control pill raises heart attack risk, especially in some women

A new review suggests that low-dose birth control pills, which are generally considered to be safer than the pill of the past, still carries an increased risk for heart attack and stroke.
