Sperm Affected By Age Of Men
Problems with fertility have always been associated with women, particularly women of a certain age. But contrary to popular belief that men are fertile more or less throughout their entire lives, research has shown that age can also affect a man’s ability to be fertile.
A scientific study carried out at Soroka University in Israel examined the semen quality and quantity of men of varying ages to compare the differences. The frequency of sexual activity (how often the men had sex) was also compared and it was found that that also had an impact of the quality of semen. Abstaining from sex completely also had a marked impact on the quality and quantity of sperm, while some believed the less sex you had the more fertile you would become, the lesser the frequency of sex the poorer the sperm motility (movement of sperm).
Results of the study conducted showed that the quantity of sperm was at its greatest in men in their early to mid-thirties. Sperm quantity was at its lowest in a man of 55 and over. Sperm motility was said to be at its best in young adults fewer than 25 and at it’s lowest in men over the age of 55 with a 54% decrease in sperm motility. In this case, it did not matter how often the men had sex, men over the age of 55 have a definite lack of quality, quantity and poor sperm motility.
Age is also found to affect the genetics of male sperm. A study carried out at the Lawrence Livermore National Laboratory (LLNL) and the University of California showed that the likelihood of defects in sperm is doubled the older a man gets. This can cause lesser fertility, birth defects and making it more possible for miscarriage. Men fathering children later in life are more likely to pass on genetic problems to their children.
Another additional study conducted in Israel at the Assuta Medical Center in Rishon LeZion showed that IVF (In Vitro Fertilisation) a treatment where egg cells can be fertilised by sperm outside the body, was more successful in men under 40. This suggests that over the age of 40, the quality of sperm is particularly poor and therefore IVF treatment has a higher chance of failure even if donor eggs are used. The age of the woman made no significant difference.
This goes to show that just like women have a biological clock so do men and that age certainly does affect the quality, quantity and motility of sperm as well as the chances of fathering a child.
How Long Can Sperm Survive
Sperm is produced by the testicles, or testis which is one of the two male reproductive glands that produce spermatozoa (sperm) and emit androgens (male sex hormones). It takes the testicles 90 days to produce fresh sperm and they are stored in an organ called the epididymis until they are mature and develop the ability to swim. It is unclear how long sperm can survive for when inside the epididymis although it appears that the health of sperm is at its optimum best when ejaculations occur every two to three days.
In a female, if sperm is ejaculated directly into the vagina, it can fertilise an egg for up to five days. The woman’s cervical mucus and the hormones in the mucus can help the sperm to survive. Sperm, in the vagina, will only survive about six hours due to the very acidic nature of the vaginal secretions. The cervical mucus that is existing when ovulation is near is much more alkaline and more welcoming to sperm. The egg white consistency of the cervical mucus helps the sperm move more easily through the vagina to the cervix, increasing the chance that the sperm will be in the correct location for fertilization to occur.
In women who are less sexually receptive, the sperm will survive much lesser durations. In many cases, the sperm will live less than three days. Some research has shown that some sperm is capable of surviving in the Fallopian tubes up to 7 days, but overall the average amount of time being 3 to 4 days.
In sperm that is stored in a sterile condition for example a container when stored at a fertility clinic it can survive for up to four hours. Some semen samples are kept in liquid nitrogen at -196 Celsius, the sperm that survives and can be kept alive for over 50 years. Sperm exposed to air lose their ability to swim, if sperm is kept moist it can survive, once semen begins to dry it dies.
Some women who not want to become pregnant will use a spermicide, usually in the form of a foam or a gel. It is not a commonly used method these days. This not only blocks the sperm’s access to the cervix from the vagina it prevents the sperm’s motility (movement) and the chemicals in the spermicide drastically effects the life of the sperm cell. Studies show that woman still has a 15% chance of becoming pregnant using this method.
The sperm’s survival rate can be determined by the female’s ability to nourish sperm in the cervix as well as the man’s age, volume, quality, quantity and motility of sperm after ejaculation.
