Our investigation showed that Zn contained many unique properties in human, especially males. The antioxidant quality is one of them. Also, the increased reactive oxygen species levels in the seminal plasma of men who are both infertile and smokers influence the Zn content of seminal plasma in a way that physiology of spermatozoa can be affected as well. Moreover, Zn acts as a toxic repercussionagainst heavy metals and cigarette inflammatory agents. It plays a role in epithelial integrity, showing that Zn is essential for maintaining the lining of the reproductive organs and may have a regulative role in the progress of capacitation and acrosome reaction.
Sperm Count Zero
Scientists investigate sperm-boosting nutrient which may help infertile couples -- ScienceDaily
The trend in parenthood at an older age has also been seen in men. Age-related infertility will continue to be a problem. A basic understanding of the issues is critical for health care professionals so that they can effectively counsel patients who are considering a delay in childbearing for social reasons or for those seeking fertility treatments. This review details the changes in fertility seen in the aging male. In recent decades, infertility has impacted an increasing number of couples. The trend for parenthood at an older age has also been seen in men. Beyond the fact that older men tend to have older female partners, increasing male age is associated with increased time to conception.
Smoking Marijuana Linked to Better Sperm Counts in Surprising Study
Scientists at the University of Sheffield are launching a pioneering study to investigate if a simple extra nutrient can boost male fertility. Studies have already shown that lycopene, the red pigment compound found most readily in sun-ripened tomatoes, can boost sperm count by up to 70 per cent, as well as conferring other benefits on the male reproductive system. It is estimated that one in six couples are unable to conceive -- in about half of cases the problem is caused by poor sperm quality. Professor Pacey said: "Studies elsewhere in the world have shown that the antioxidant properties of lycopene seem to have a beneficial effect on sperm quality and we want to investigate this further. This study will tell us if lycopene improves the quality of sperm already in development by reducing DNA damage, and whether it produces an overall increase in the number of mature sperm produced overall.
Is there enough? Is the existing supply satisfactory? Are we men enough?
