Obesity And Abnormal Sperm

In the 24th annual conference of the European Society of Human Reproduction and Embryology, Dr. A Ghiyath Shayeb said that men with a higher body mass index (BMI) have lower volumes of seminal fluid and a higher proportion of abnormal sperm. If you want to be fertile and have babies, you should consider losing some weight, and maintain your body weight to normal BMI. Living a healthy lifestyle with a balanced diet, regular exercise are needed to be in the normal BMI range.

Ticking Male’s Biological Clock

More evidence were found that men as well as women have ticking biological clocks that start to tick in mid-30s. A study done on 12,200 couples proved that the chance of a successful pregnancy falls when the man is over 35, and it is significantly lower if he is over 40. The researchers told in a health conference that it was due to the DNA damage in sperm.

Same Sex Attractions Are Natural

Is homosexuality natural? Scientists say that the same-sex attraction is common in many species. Two male penguins at New York’s Central Park Zoo were a couple for 6 years. These penguins nurtured a fertilized egg together given by a zoo keeper.

There are more than 1,500 animal species are known to practice same sex coupling. This includes owls, salmons, bears, gorillas, flamingos and many others. So why evolution hasn’t eliminated this trait since it doesn’t lead to reproduction. The answer is that this type of coupling may simply be for pleasure. Not every sexual act lead to reproduction.
