Article about the effects of weight,age and gender on infertility:
“In fact, a study released yesterday shows research on the repercussions of female ageing on fertility has produced 981 papers since 1952, while study on the male impact has been a mere 10 papers - the first published in 1982. ”
AUSTRALIA - “THE Health Minister, Tony Abbott, is under pressure to release a report which is believed to recommend an expansion of Medicare funding for in vitro fertilisation services, a treatment he is opposed to.”
“A man’s infertility could be directly linked to his body weight, a current American-based study reveals. Data from the National Institute of Environmental Health Sciences (NIEHS) suggests that overweight men are significantly more likely to be infertile than normal-weight men, and that for every 20-pound body weight gain in men there is a ten per cent increase in infertility.”
“Researchers have found that women who continue to exercise while they are trying to conceive using IVF may reduce their chances of conception. The research, published in the October issue of the journal Obstetrics & Gynecology, found that women who regularly exercised for more than four hours per week - and who had done so for one to nine years previously - were 40 per cent less likely to have successful IVF treatment than women who didn’t exercise.”
The British Fertility Society conference was told that older women having IVF and other procedures faced higher health risks, as did their babies.
The meeting in Glasgow also heard that denying them treatment was age discrimination and a human-rights abuse. But a majority of delegates backed a motion that fertility treatment should not be available to women over 50. There is no legal age limit, but most clinics are unwilling to treat women over 46.
“Biologists have developed a technique for establishing colonies of human embryonic stem cells without destroying embryos, a method that, if confirmed in other laboratories, would seem to remove the principal objection to stem cell research”
“A new study has reported its findings that heavy mobile phone use is correlated to a decline in male fertility. The study, led by Dr Ashok Agarwal, and reported at the annual meeting of the American Society for Reproductive Medicine in New Orleans, found that men who talked on their mobile phones for more than four hours a day had lower sperm counts than infrequent, or non-users of mobile phones.”
“The American Society for Reproductive Medicine (ASRM) and the US Society for Assisted Reproductive Technology (SART) have issued new guidelines limiting embryo transfer during IVF procedures to reduce the occurrence of multiple births. Announced at the annual ASRM meeting, held in New Orleans last week, the revised guidelines recommend that no more than two embryos should be transferred to women under 35 during a single cycle of IVF treatment, and that clinics should consider the possibility of transferring only one. For older women the recommended number of embryos increases, but to no more than five. The guidelines state that for women aged between 35 and 37, up to three embryos should be transferred, with up to four recommended for women aged between 37 and 40, and no more than five for women over 40.”
“Researchers at Cornell Medical Center in New York have discovered that commonly prescribed anti-depressants may have the unwanted side effect of drastically lowering male sperm count. Tests were conducted on two men over a two year period, during which time their sperm count changed from normal before taking the anti-depressants, to almost zero after taking the medicines. The sperm count of both men recovered to normal levels once use of the drugs was discontinued.”
“Experts are expected to recommend today that fertility doctors try to prevent twin and triplet pregnancies. Doctors will be advised that multiple births are so risky for the mother and babies that in most cases they should only place one embryo in the womb.”
“European males are now, for the first time, more likely to be the infertile half of couples attending fertility clinics, according to a report last year from the European Society for Human Reproduction and Embryology.In Australia, it’s thought men are just as likely to be the cause as their partner, but male infertility is rising faster and may soon become the main cause.”
Bionews reports from the the European Society of Human Reproduction and Embryology (ESHRE) annual conference about a Belgian study that shows that children born from intracytoplasmic sperm injection (ICSI) are still developing well 8 years after birth (ICSI was introduced in 1991). This study looks at physical development.
