We also recommended that couples trying to conceive stay away from harmful chemicals. This might be because of less sexual activity, lower semen volume, changes to sperm movement, a lower number of properly working sperm, or possibly lower sperm function and DNA quality.

The chance of the child having some genetic or chromosomal problem also gets higher when you get older. Talking with a doctor, a sexual therapist or counsellor can often help with any negative feelings you might be having. How long have you and your partner been trying to conceive? Have you been having sex at least twice a week during this time?
Discovery of new genetic causes of male infertility
Do you and your partner focus sex on the fertile time of the month and how do you know when that is? Did you have undescended testicles as an infant? Have you ever had pelvic surgery or treatments for cancer? You are here Mens health.
Male infertility. What is male infertility?
How common is infertility? What are the symptoms of male infertility? What causes male infertility? Sometimes, male infertility is simply genetic. What are the genetic causes of male infertility? How is infertility diagnosed? What are the treatments for infertility? Can I do anything to prevent male infertility? Can older age cause male fertility problems? The development of in vitro fertilitzation IVF has allowed many couples to have the families they might otherwise have been unable to create independently. At the same time, this technology has allowed researchers to study the genetic make-up of the earliest stages of embryos.
These advances are providing insights into the link between genetics and infertility and how defects mutations in specific genes may result in male or female infertility. It is possible that many cases of unexplained infertility will one day be found to have a clear genetic basis. What has been learned in the last two decades of assisted reproduction is that some cases of severe male factor infertility are clearly related to gene deletions, mutations or chromosomal abnormalities.
Some men with very severe male factor infertility will be found, upon testing their blood chromosomes known as a "karyotype" to have an extra X chromosome. This condition is known as "Klinefelter Syndrome" and can result in failure to achieve puberty or even when puberty is achieved, these men often have male infertility. So far, we are not seeing an increased risk of Klinefelter Syndrome or other chromosome abnormalities in the offspring achieved in these cases.
