What You Eat or Drink May Help You Get Pregnant

What goes inside a body may have a significant effect in improving female fertility, suggests a study.

Dr. Emma Derbyshire and her team, from Manchester Metropolitan University, has found that controlled diet may enhance the chances of getting a positive pregnancy test, even to the point of being as effective as IVF treatment.

The researchers observed that while intrauterine insemination and ovarian stimulation showed a success rate of 33% in conception, dietary advice was virtually as effective, giving a 32% success rate, reports Times Online.

They suggest that some efforts that may help increase a woman’s chances of becoming pregnant, and delivering a healthy baby.

These included restrictive methods like abstaining from alcohol, cutting down on caffeine levels or switching to decaffeinated versions.

Emphasis was also put on the inclusion of plenty of fruit and vegetables in daily diet, which could help to put off the reproductive years.

More Sex May Help Damaged Sperm

For men with fertility problems, some doctors are prescribing a very conventional way to have a baby: more sex.

In a study of 118 Australian men with damaged sperm, doctors found that having sex every day for a week significantly reduced the amount of DNA damage in their patients’ sperm. Previous studies have linked better sperm quality to higher pregnancy rates.

The research was announced Tuesday at a meeting of the European Society of Human Reproduction and Embryology in Amsterdam.

Dr David Greening of Sydney IVF, a private fertility clinic in Australia, and colleagues looked at 118 men who had damaged sperm. Greening and colleagues told the men to have sex every day for a week. After seven days, the doctors found that in 81 percent of the men, there was a 12 percent decrease in the amount of damaged sperm.

Many fertility experts suggest men abstain from sex before their partners have in-vitro fertilization, to try to elevate their sperm counts.

Sperm quality can also be improved if men don’t smoke, drink moderately, exercise, or get more antioxidants.

Since concluding the study, Greening says he now instructs all couples seeking fertility advice to start by having more sex. “Some of the older men look a little concerned,” he said. “But the younger ones seem quite happy about it.”

Experts think sex helps reduce the DNA damage in sperm by getting it out of the body quickly; if sperm is in the body for too long, it has a higher chance of getting damaged.

Some experts said that while Greening’s research is promising, it doesn’t prove that daily sex for men with fertility problems will actually produce more babies.

Greening said he and his colleagues are still analyzing the study data to determine how many women got pregnant.

“Looking at sperm DNA is just one part of the puzzle,” said Bill Ledger, a professor of obstetrics and gynecology at the University of Sheffield, who was not connected to the research. “Maybe this will improve pregnancy rates, but we still need to do more studies.”

Ledger said instructing couples with infertility problems to have more sex could stress their relationship. “This may add even more anxiety and do more harm than good,” he said. He said couples shouldn’t feel pressured to adjust their sex lives just for the sake of having a baby.

Greening said the study’s findings were ultimately very intuitive. “If you want to have a baby, our advice is to do it often.”

Common Chemicals Threaten Male Fertility

A leading scientist has warned that chemicals found in many food, cosmetic and cleaning products pose a real threat to male fertility. Professor Richard Sharpe, of the Medical Research Council, says that these hormone-disrupting chemicals are “feminizing” boys in the womb, leading to rising rates of birth defects, testicular cancer, and low sperm counts.

It is thought that all these conditions, collectively called Testicular Dysgenesis Syndrome (TDS), are linked to disruption of the male sex hormone testosterone. Professor Sharpe concluded that exposure to a cocktail of hormone-disrupting chemicals in the environment is likely to be at least partly to blame by blocking the action of testosterone in the womb.

His latest report highlights animal studies showing that testosterone-disrupting chemicals can cause TDS-like disorders.

‘High temp leads to infertility’

NEW DELHI: Researchers recorded the temperature changes to the scrotum caused by laptop use among 29 healthy male volunteers aged between 21 and 35 and found that just sitting with thighs pressed together, caused scrotal temperatures to rise by 2.1 degrees C.

The AIIMS study also found that majority of men who were exposed to high temperature at their work places welders, dyers, blast furnace workers, cement and steel factories are also more prone to infertility. All this happens because even small changes in temperature have a negative effect on sperm production.

Testes are located outside of the body, suspended by the spermatic cord within the scrotum. This allows for more efficient and fertile sperm production.

The temperature of the testes is usually three degrees lower than the core body temperature (37 degrees C or 98.6 degrees Fahrenheit). Even one degree elevation in testicular temperature leads to 14% depression of spermatogenesis.

“Not only has quantity of sperm production declined in males across the world, there has been a decrease in mortility (sperm movement) and morphology (shape and structure) of the sperms.

“There has been a 2% decrease in quality of male sperm annually. Also, 40% men in the reproductive age group are at present recording a quantitative and qualitative decline in sperm quality,” Dr Dada said. The study also found that nearly 20% of infertile men with low sperm count, or oligospermia, harboured genetic abnormalities.

The abnormality either involved sex chromosomes or autosomes or micro deletions in the ‘Y’ chromosome, said Dada. The ‘Y’ chromosome harbours the gene critical for germ cell development and differentiation, without which a person will have no sperms or will have very low sperm count.
