Sperm Concentration Boosted With Zinc, Folic Acid Men who are
subfertile may want to consider taking a course of folic acid and zinc sulphate
to increase their chances of fathering a child. It seems that these dietary
supplements can boost sperm concentration, says a study in the International
Journal of Andrology.
The Netherlands based researchers analyzed the sperm of both fertile and
subfertile men, some who received a course of folic acid (5 mg/day) and zinc
sulphate (66 mg/day), and others who received placebo. The researchers also
recorded levels of the hormones testosterone, follicle stimulating hormone (FSH)
and inhibin B in all the men.
The researchers found that the folic acid and zinc sulphate course of
treatment significantly increased the sperm concentration in the subfertile men.
In addition, they noted that other semen and hormonal parameters were not
affected by the supplement treatment.
However, the researchers say the reasons behind why these two supplements
increase sperm concentrations are not immediately obvious. "We conclude that the
increase in sperm concentration after folic acid and zinc sulphate intervention
is not the result of alterations in FSH, testosterone or inhibin B
concentrations. Although zinc and folate have several effects on
spermatogenesis, the underlying mechanisms involved are not clear," they said.
While the reasons behind the change in sperm concentration remain something
of a mystery, the results should be of interest to men who are trying to
conceive with less than optimal sperm parameters. The study was carried out over
a 26 week period so it may be that subfertile men should consider a course of
dietary supplements over a similar period to boost their chances of becoming a
father. |
