Sperm Mapping And Sterilization: Know It All

When a man gets diagnosed as being sterile, it does not imply that his body is not making sperm; it just implies that there’s no sperm when he ejaculates. Sometimes, it can be because of a blockage in the system, but most of the time the body simply doesn’t make enough sperm to discharge. In the United States, approximately 2,000,000 men have infertility problems. About 30% of all infertility problems are mainly because of infertility in men. 

Infertility affects men and women. In couples experiencing infertility, approximately 35% is due to male factors, 35% is due to female factors, 20% of cases have a combination of both male and female factors, and the last 10% are unexplained causes.

About a third of all infertility issue cases are due to fertility in men. These can range from low sperm count or sperm abnormalities to hormonal imbalances or problems related to the reproductive anatomy. Health and lifestyle factors such as stress, weight, and alcohol consumption can also play a role. The good news is that infertility treatment options are available.

What is Sterilization ?

Male Sterilization— also called vasectomy— is a surgery. It is intended to ensure protection against pregnancy permanently, so it is highly effective. Male Sterilization is a medical procedure performed by a specialist. The little tubes in the scrotum that take sperm are removed or blocked off, so sperm cannot leave the male body and cause pregnancy. The technique is exceptionally fast, and the patient can return home that day itself. Also, it is amazingly powerful at forestalling pregnancy — practically 100%. Sterilization is intended to be permanent— so they, as a rule, can’t be reversed. 

How Does Sterilization Work?

Sperm— the microscopic cells that get together with an egg to cause pregnancy — are made in the testicles. Sperm leaves the testicles through two tubes called the vas deferens, and blends in with different liquids to make semen. The sperm in the semen can cause pregnancy if it gets a  chance to gets into a vagina.

Sterilization blocks or cuts every vas deferens tube, keeping sperm out of the semen. Sperm cells remain in the testicles and are absorbed by the male body. Beginning around three months after sterilization, the semen won’t contain any sperm, so it cannot cause pregnancy. Despite sterilization, the male body will have a similar amount of semen discharge as before. There just won’t be any sperm in it. 

Sterilization does not change the way of having an orgasm or ejaculating feels. The semen will look, feel, and taste the same even after sterilization— it just won’t have the option to get a female pregnant.

Is Sterilization Effective?

Sterilization or vasectomy is one of the best types of conception prevention out there and it is the most effective for successfully achieving infertility in men. Sterilizations are practically 100% viable at forestalling pregnancy — however not immediately. It takes around 3 months for the semen to become sperm-free.

A couple of months after your sterilization, your doctor will do a basic test called a semen analysis to check for sperm count in your semen. You will have to masturbate into a cup or use a special condom when you have intercourse to gather a semen sample. Your doctor will reveal to you when there is no sperm in your semen and the sterilization is filling in as contraception. You should not indulge in unprotected sex until your doctor says it is safe.

Though, there is a slight possibility that the cut ends of the vas deferens can grow back together after the sterilization, which implies you could cause a pregnancy. But, this is very uncommon.

Benefits and Risks of Sterilization

Sterilization is an effective and permanent approach to avoid pregnancy. It’s best for men who are sure and they willingly don’t want to have children. It doesn’t have any impacts on sexual activity or performance. Male sterilization is simpler and more affordable than female sterilization.

Getting a vasectomy is usually really safe. But like all medical procedures, there can be some risks. Things like temporary pain, bruising, and infection are the most common ones. You can also experience:

  • A fever over 100° F.
  • Blood or pus coming from where the cut was made in your scrotum.
  • Lots of pain or swelling in your scrotum or testicle area.
  • Bleeding where the skin was cut.
  • Bleeding under the skin that may cause swelling or bruising (called hematoma).
  • Swelling (called Spermatic Granuloma) caused by sperm leaking from your vas deferens. It usually goes away on its own, but a doctor may need to drain it.
  • Temporary pain or discomfort is common.

Sperm Count

Low Sperm Count implies that the liquid or semen you discharge during an orgasm contains less sperm than normal. It is also called oligospermia. 

A total absence of sperm is called azoospermia. Your sperm count is viewed as lower than normal if you have less than 15 million sperm for every milliliter of semen. 

Having a low sperm count lessens the chances that one of your sperm will fertilize your partner’s egg, resulting in pregnancy. Nonetheless, many men who have a low sperm count still have the ability to become a father. Low or no sperm count can be determined by a procedure called sperm mapping.


What is Sperm Mapping?

Sperm Mapping or Testes Mapping is where various fine needle biopsies or FNA are done on the testicles with the goal to check whether there are any areas where sperms are produced. This test is valuable in light of the fact that the testicles are “heterogeneous” implying that various areas of the testicles have different patterns of sperm creation. A dominant part of the areas of your testicles may produce no sperm, yet there might be some harder-to-discover zones that do. The significance of sperm mapping is that it can let us know whether there are sperm-producing regions in the testicles, and where they are. 

On the other hand, if no sperms are found during this test, it is assumed that there are no sperm being produced anywhere in your testicles. No further assessment is necessary and it spares the man from experiencing an open testicular biopsy and keeps the couple away from experiencing an unproductive in vitro fertilization cycle.

How is Sperm Mapping Done?

After a local anesthetic is given, the testicles are pushed up against the skin and a grid is drawn on the skin with a marking pen. By and large, 18 biopsies are done on each side. These biopsies are performed with a fine needle, which goes all through the testicles a number of times.

The cells are then positioned onto a particularly labeled slide. A report on each side is recorded. Together these individual reports make a “sperm map” with regards to where sperm, if any, can be found. If sperm are discovered, various procedures can be used, on the basis of this report, so as to attempt to get sperm from specific areas and use them with an in vitro fertilization cycle with ICSI so as to attempt a pregnancy.


There are some advantages to this technique:

  • It is less intrusive than a microscopic testicular sperm extraction. 
  • There is less possibility of causing testicular damage, and changes in the capacity of the testicles to make testosterone.
  • It is done in advance of an in vitro fertilization cycle.


The disadvantage of this technique is that if sperms are discovered, the patient must undergo a second ensuing procedure in order to harvest or recover the sperm and use them for injection into their partner’s oocytes. However, in those men where no sperms are found, the man won’t experience the more obtrusive TESE, and the woman will not need an IVF.

What Is Good Sexual Health And Why Is It Important?

Being sexually healthy means having the option to appreciate a healthier body, a wonderful sexual life, positive connections, and genuine feelings of serenity. Being sexually healthy also means making the most of your sexuality and taking care of yourself and your partners for life. 

A few important benefits of good sexual health:

  • A more beneficial body.
  • A delightful sexual coexistence. 
  • Esteeming and liking yourself. 
  • Having genuine feelings of serenity. 
  • Positive and fulfilling connections. 
  • Maintaining a strategic distance from explicitly transmitted contaminations (STIs), otherwise called explicitly transmitted sicknesses (STDs). 
  • Avoiding impromptu pregnancies.

Allow yourself to discuss sexual health and wellbeing with your partner, as it is the key to a good and healthy life!
