Male infertility starts around age 40 to 45 years when the quality of the sperm starts decreasing. The increase of male's age also lowers the chances of pregnancy as well as increases the number of menstrual cycles which it is needed to become pregnant. On the part of women, it increases the risk of fetal death and miscarriage.
One of the common reasons behind infertility in men is their sperm motility which reduces as age escalates. It is considered to be best before the age of 25 and lowest after the age of 55.
In the comparison of 'good swimming' sperm in men, the men whose age is between 30 to 35 have increased sperm motility while the ones over the age of 50 have decreased sperm motility.
Sexual abstinence cannot be the only reason for such strong variations.
What are some of the risks of Genetic Problems?
One of the common features of infertile men is low-quality semen. Genetic quality is also affected by age.
Such genetic sperm defects might cause the following:-
Higher chances of miscarriage
Higher chances of stillbirth
Higher risk of congenital disabilities
According to scientists, older men are not only prone to infertility. They also constitute the risk of spreading genetic problems to their child. A combination of both male age as well as female age can escalate the risk of stillbirth defects.
For instance, there is a risk of Down Syndrome. In the case of women, the risk of giving birth to a child who would have down syndrome increases more with age.
Down syndrome is just an example. There are various other risks associated with an increase in age. Older father's constitute the higher chances of having babies with disorders such as:-
achondroplasia, another name of dwarfism
When a woman gets pregnant at the age of 35 or older, that's when the age of men matters a lot; in such cases, children are born with some diseases such as down syndrome or any genetic defects.
When is it recommended to see a doctor?
You should consult a doctor if you cannot conceive a child for more than one year despite having unprotected sex. You can also see a doctor if you are familiar with either of the following cases: -
Swelling, discomfort, lump, or pain in the area of the testicle
Low Sex drive
Ejaculation or erection problems
Issues related to sexual function
A history of sexual problems, prostate or testicle
Surgery of groin, scrotum, testicle, or penis
An experienced expert can adequately check the count of the sperm, movement as well as shape along with other different characteristics. Usually, if there is a higher number of normal shapes of sperm, this generally means that man has higher fertility. But there are some exceptions to it since many men with low sperm counts or even abnormal semen could be still fertile.
