HIV transmission among gay partners may be prevented using medication, finds new study

One of the largest studies undertaken has explored the risk of transmitting HIV infection by an HIV infected partner to his non-infected gay partner. Results reveal that HIV positive men who are on medication for HIV that makes their virus load undetectable in blood are not likely to transmit the infection to their non-infected partners.

Effects of declining sperm counts on fertility, mortality and disease patterns in geographical areas: Study

There is a lack of definitive data on the actual trends of decline in sperm counts according to researchers despite it being a known fact. Researchers in a new study looked at a large population to find the exact data regarding this scenario and its effects on the society. They looked at the effects of fertility and geographical distribution on the sperm concentration as well as total sperm counts.

Novel technique analyzes sperm morphology and motility in embryo formation process

The research, presented at the European Society of Human Reproduction and Embryology annual conference, which ends today in Geneva, Switzerland, describes for the first time the use of an experimental technique that has made it possible to analyze the functioning of human sperm in contact with the cytoplasmic content of the eggs in vitro.

Increase in male partner’s age associated with decline in cumulative live birth rate, study finds

A new study of IVF couples, conducted in the USA, finds the effects of the age of male partners in cumulative live birth outcomes. The results clearly state that there can be a significant reduction in the chances of live births owing to the increased age of the male partner, also seen with certain younger female age groups whose age has less potency on the effects.
