Contrary to popular belief, infertility in women is not the only factor that may lead to repeated miscarriages, as a new study published this year linked poor sperm quality and miscarriage.
And the results of research - conducted by scientists at the University of Imperial College in London - showed that the sperm of men whose partners had suffered three or more times of consecutive pregnancy loss had high levels of DNA damage.
Research results indicated that the damage is caused by the high concentration of reactive oxygen species that protect sperm from bacteria and infection.
Dr. Francisco Ruiz, the medical director at the IVI Middle East Fertility Clinic in the Sultanate of Oman, said that one miscarriage does not usually indicate any underlying fertility problem, and husbands may eventually conceive.
Further testing is recommended after a third miscarriage to find the root of the problem, and doctors usually suggest examining the chromosomal mutations that can be found in both the egg and sperm.
Ruiz added that for wives who undergo IVF and have a history of repeated pregnancy loss, genetic testing is performed before implantation to diagnose genetic and chromosomal changes in fetuses before they are implanted in the womb.
He concluded, "We still cannot confirm the full impact of poor sperm quality and its relationship to the occurrence of miscarriage. Like other fertility problems, we always recommend that couples consult a fertility expert to find out the best way forward in looking at their condition and helping them to have a normal child."
