Oxygen kill male sperm

Multiple miscarriages may be linked to the poor quality of a man's sperm, suggests new research. The early-stage study, from scientists at Imperial College London, investigated the sperm quality of 50 men whose partners had suffered three or more consecutive miscarriages. The research, published in the journal Clinical Chemistry , revealed that, compared to men whose partners had not experienced miscarriages, the sperm of those involved in the study had higher levels of DNA damage. The study team hope these findings may open new avenues to finding treatments to reduce the risk of miscarriage. Recurrent miscarriage affects around one in 50 couples in the UK, and is defined as the consecutive loss of three of more pregnancies before 20 weeks gestation. Until recently recurrent miscarriage was thought to be caused by health issues with the mother, such as infection or immune problems.

Semen analysis and sperm function tests: How much to test?

Semen analysis as an integral part of infertility investigations is taken as a surrogate measure for male fecundity in clinical andrology, male fertility, and pregnancy risk assessments. Clearly, laboratory seminology is still very much in its infancy. In as much as the creation of a conventional semen profile will always represent the foundations of male fertility evaluation, the 5th edition of the World Health Organization WHO manual is a definitive statement on how such assessments should be carried out and how the quality should be controlled. A major advance in this new edition of the WHO manual, resolving the most salient critique of previous editions, is the development of the first well-defined reference ranges for semen analysis based on the analysis of over recent fathers.
