FERTILITY decreases with age for a woman and also for a man although in different ways and to different degrees. One of the most important factors that determine fertility is age.
As a man, you are probably aware that women’s fertility declines after the age of 35, but do you also know that your age can affect your ability to become a parent, too?
While less is known about male fertility and age, there is increasing evidence that the older a man becomes, the more his fertility diminishes. You can’t change your age, but with knowledge and proper education, it is possible to improve your chances of successfully fathering a child.
As earlier established, while it is not impossible for an older man to father children, it may not always be possible. Many men actually remain fertile until they are 60 or older, however, ability to father a child does become more difficult and complicated with age.
From practical experience, it takes longer to father a child the older you are. If you are over 50 and your woman is under 25, it can take about two years for her to get pregnant. On the other hand, if both of you are under 25, it could take just a few months on average. If you are over 45 it could take five times as long for you to father a child that when you were under 25.
The fact really is that with advancing age, even In vitro fertilization (IVF) becomes more challenging. The risk of not having a baby after IVF is more than five times higher if the male partner is 41 years old or older.
One of the reasons why fertility decreases with age has to do with the volume and quality of the sperms. For a start, semen volume decreases with age. The amount of semen that you produce, as well as the sperm’s ability to move towards an egg, decreases continually starting at the age of 20.
Semen consists of mobile sperm cells and seminal fluid that transports the sperm cells and enhances their fertilization abilities.
Sperm cells are produced in the testes, stored in the epididymis, and comprise less than 10 percent of semen. Ejaculation occurs when semen is released from the penis, usually during orgasm. Ejaculate, or semen, is made up of 90 percent water. The opacity tends to increase with higher sperm concentrations (as measured by the sperm count).
Sixty-five percent of the semen present in an ejaculation comes from the seminal vesicles, 35 percent comes from the prostate, giving the semen its characteristic smell. Five percent of your ejaculate is made up of other fluids in the body. During ejaculation, a thick-walled duct called the vas deferens carries the sperm cells from the epididymis to the urethra and then outside of the body or into the vagina by means of the penis.
The prostate gland also releases enzymes that work to liquefy semen about 15 to 30 minutes after ejaculation. This liquefying process allows the sperm to be slowly released.
The normal volume of semen that is released during ejaculation varies, although research suggests that the average volume is around 3.4 ml. Also, two factors that may affect semen volume during ejaculation include the last time you ejaculated and hydration status.
A healthy male discharges 50 million sperm in a single ejaculation. During sexual intercourse, of all those millions of sperm, only a couple hundred will make it to a mature egg that is ready to be fertilized.
Generally speaking, a sperm count of under 39 million per ejaculation or 15 million per milliliter lowers your odds of a successful conception. It doesn’t mean you won’t get pregnant or that there aren’t assisted means to improve your odds.
If you are struggling with fertility, a semen analysis will reveal if any aspect of your semen may be a contributing factor.
Your semen is not as simple as you may have thought. It has lots of components to it, all of which play a role in enhancing reproduction—your sperm reaching an ovulated egg. However, it’s important to note that the fluid part is not absolutely critical for fertilization, as evidenced by intracytoplasmic sperm injection (ICSI) in which a single sperm is injected into an egg.
When you are aging, you will ejaculate less semen-containing sperm. You will also experience fewer orgasms.
Normally, multiple orgasms are rarer for men than they are for women. The ability to have repeated ejaculation varies considerably from man to man and begins to decline almost immediately once puberty is complete. Within a period of one to two hours, most men can have only one ejaculation.
Excessive ejaculation and prolonged abstinence are known to affect the number and quality of sperm.
