A man’s diet is important

A 2011 study from Boston, USA, has shown that men with diets high in the bad saturated fats contained in junk food had much lower sperm levels than men of a similar age who ate a healthier diet rich in the omega-3 polyunsaturated fats found in olive and canola oils. A healthy diet rich in fibre, fruits and vegetables is recommended not only for boosting fertility, but also for reducing the chance of developing cancer, stroke and heart disease.

Treatment for low sperm count actually makes male sperm counts worse.

Testosterone is the male hormone, traditionally known to lead to the typical male-traits of bulky muscles, body & facial hair, sexual drive and strength. In the past urologist tried giving testosterone injections to men with low sperm counts in an attempt to increase sperm production. The treatment become obsolete years ago when it was realized that testosterone actually blocks sperm production. A 2009 trial in China showed that testosterone injections may be the long-awaited new male contraceptive. Of the 1000 men in the trial less than 1 in a 100 fathered a child while taking the testosterone injections, which comes close to the success rate of the birth control pill in preventing pregnancy. More trials are needed to check the safety of the testosterone injections before it becomes available.

Babies born from frozen embryo transfer are healthier than fresh IVF embryos.

Freezing spare embryos during an IVF cycle is known to be safe and result in healthy babies. Now, new research is suggesting that frozen embryo babies might actually be healthier than babies where the embryo was transferred in a fresh cycle. In a 2011 London study,  108 babies born after frozen embryo transfer were significantly better weights and had less pre-term birth than 384 babies born from embryos transferred during a fresh IVF cycle. At the moment the reasons for this difference are not clear.

Can laptop computers and WiFi damage male fertility?

This is a good question. Sperm counts have been dropping worldwide for the last 100 years and scientists remain baffled as to all the reasons. In a recent study from Argentina scientists have shown that ejaculated sperm from 15 men showed damage to both the swimming ability and genetic integrity after exposure to a laptop computer connected to WiFi. The study was small and experts have warned that other factors could explain the damage seen in the sperm. At present we advise men to avoid having laptop computers on their lap. Apart from potential damage to sperm the heat generated underneath the laptops caused significant heating in testicles which is thought to reduce sperm quality.
