Older Men Having Children

Many women who get pregnant at older age already understand the risks involved – for both them and their child. On the other hand, men are still unaware of the risk their old age can have in the event that they have a child (Source). As more millennials are putting off having kids, the average age of parents is growing, as parents opt to get stable careers before having children. This trend has numerous implications for women and children’s health.

Older Men Having Children

While delaying marriage and having children does allow a stable lifestyle for children, having older parents can have an effect on their development.

Parental Age and Baby’s Health

Research pertaining to parental age and child health shows that there are numerous misconceptions about the best time to have a child.’ While this field still requires immense research, there are some scientific answers based on biology. According to the studies, children whose parents had them after crossing their 40s face the risk of developing the following conditions:

1.    Schizophrenia

Some studies suggest that older parental age might lead to numerous risks for the baby. These risks include mental disorders, such as schizophrenia. Furthermore, the child may start to experience symptoms of schizophrenia at an early age.

2.    Pregnancy Loss

Higher maternal or paternal age can increase the risk of stillbirth or miscarriage increases. In women, the womb may not be as strong as it used to be.

3.    Autism

According to some cases of research, there is a correlation between increasing cases of autism spectrum disorder and older parental age.

4.    Childhood Acute Lymphoblastic Leukemia

Children with older parents face a higher risk of acute lymphoblastic leukemia at an early age. This condition is cancer and is an abnormality in the production of white blood cells. Since white blood cells are crucial components of the immune system, this disease means that the child will have compromised defenses against various infections and diseases.

5.    Rare Birth Defects

When parents decide to have a child at an older age, there is a higher risk of the child experiencing rare birth defects. This includes defects in the development of the heart, limbs, and skull.

What is a Vasectomy?

Vasectomy is a surgical procedure that prevents the sperm from reaching the seminal fluid. It implies that the ejaculate will be free from sperm cells, which are crucial for conception. While you will continue to release semen, the tube connecting transfer of the sperm to semen is no longer connected. A vasectomy doesn’t affect your body’s ability to produce sperm. You will continue to produce sperm normally, but your body will absorb it as they accumulate in the scrotum.

In the United States, more than 500,000 men choose to undergo a vasectomy every year. Because vasectomy is among the most effective methods for birth control, it is gaining more and more popularity. This surgery has higher efficiency and a greater success rate in contrast to other birth control methods, such as oral contraceptives, etc.

Testicles produce sperm and other male sex hormones. Sperm cells are male reproductive cells that fertilize female eggs, beginning the reproduction process. The testes are in the scrotum at the base of the penis. The sperm leaves the testes through the epididymis, a coiled tube. The sperm cells stay in the testes until you are ready to ejaculate. Epididymis connects with the vas deferens, which further connects with the seminal vesicle, forming the ejaculatory duct. The ejaculate is a combination of seminal fluid and sperm cells, called semen.

How Vasectomy Works

Sperm cells are microscopic cells that fuse with egg cells to cause a pregnancy. The sperm cells come from the testicles. The vas deferens transfer sperm and mix it with semen when you ejaculate. When you undergo a vasectomy, the surgeon will block or cut the vas deferens tube so that your semen does not mix with the sperm. The sperm cells will stay in the testicles, and your body will absorb them. After three months of your surgery, your semen will no longer contain sperm cells, losing its ability to get your partner pregnant. A vasectomy will not change the way you ejaculate or have an orgasm. Your ability to have sexual intercourse will remain the same after the surgery.

All About Vasectomies & Vasectomy Reversals

Vasectomy treatment is a birth control method that prevents the body from releasing sperm along with semen during ejaculation. A surgeon will block or cut your vas deferens. This duct helps the sperm reach the urethra from the testicles. It is possible to reverse a vasectomy, but it does not always work. Hence, make up your mind about having children before opting for a vasectomy. The chances of conceiving, even after a reversal, are low.

Vasectomies & Vasectomy Reversals Urologist

The sperm travels to the urethra from the testicles. So when the doctor cuts or seals the vas deferens, you will no longer ejaculate sperm. As a result, you can avoid unwanted pregnancies. Today, a vasectomy is an effective method for birth control. American Urological Associations suggests that only two out of 1000 couples get pregnant again after a vasectomy.

Effectiveness of Vasectomy

Vasectomies are 100% effective, but in some exceptions, the tubes rejoin, causing sperm to leave the body. After a vasectomy, your body doesn’t stop releasing sperm right away. You need to schedule follow-up appointments with the doctor, so they can check and ensure that you are completely sperm-free. If a vasectomy isn’t effective in providing the results you need, try opting for another birth control procedure.

Side Effects of a Vasectomy

Vasectomy is a safe procedure. However, you might experience some pain afterward. Furthermore, your scrotum might swell as well. It is quite possible that you may bleed a little, but since these side effects only occur rarely, a vasectomy procedure does not include serious complications. Only 1 to 2 percent of men will experience severe pain, which does go away that easily.

The complications are not common, but they might occur. Here are some possible side effects you might suffer after the treatment:

  • Infection
  • Inflammation
  • Bruising

These complications can go away with time, but if you think your condition is getting worse, you should visit a doctor and discuss your symptoms. Here are some other rare side effects:

  • Sperm granuloma (Inflammation or a hard lump you might develop after leaking sperm)
  • Pressure, ache, and discomfort in your testicles.
  • Hydrocele (This is the sac of fluid that starts to swell the scrotum.
  • Spermatocele (a cyst that you might develop in the sperm collecting tube)

Is it Possible to Reverse Vasectomy

It is possible to reverse a vasectomy, but not always. Vasectomy reversal is not easy, and it won’t work for everyone. You should not consider the procedure if you are unsure about having children in the future.

But suppose you opted for a vasectomy and now you want to reverse the procedure. In that case, you can talk to the doctor about getting the reversal.

In a vasectomy, the doctor cuts the sperm-carrying tube, vas deferens. While performing a reversal, the doctor rejoins the tubes, enabling the semen to pass through the testes to the penis while ejaculating.

Methods for Vasectomy Reversal

The doctor will perform vasectomy reversal from one out of two methods. Vasovasostomy is the first treatment that the doctor will recommend. In this technique, the doctor will sew both the ends of vas deferens. By connecting the vas deferens, the penis and testes join together.

Vasoepididymostomy is the second method your doctor might suggest. The doctor will attach the vas deferens with a small organ. This organ holds the sperm. Vasoepididymostomy is difficult and riskier than Vasovasostomy. Doctors only choose this method if a Vasovasostomy fails.

The doctor will perform the treatment in a clinic or hospital. They will provide anesthesia, so you are unconscious throughout the procedure and do not feel any pain. The procedure will take around two to four hours. However, you can go back home once the doctor performs the treatment. You will need two weeks to recover completely. You can reverse a vasectomy as many times as you want, but each time, the success rate decreases.

Preparing for Vasectomy Reversal

Here are some things that you need to know before undergoing vasectomy reversal:

  • The treatment can be expensive, and your insurance policy may not cover it. You need to confirm costs before the treatment so you can arrange for the funds.
  • Vasectomy reversals are highly successful when a professional surgeon performs them. You need to ensure the surgeon has extensive experience executing microsurgical techniques, especially one that includes a surgical microscope.
  • The Vasoepididymostomy procedure is complex, so discuss the procedure and complications with a specialist prior to the surgery.


Thoroughly consult your specialist before opting for a vasectomy or vasectomy reversal. Furthermore, you can also ask about the complication and risks of the treatment. An in-depth discussion helps you determine if it’s the right procedure for you.

Vasectomy Reversal Success Rates

Success Rates Depend on the Type of Reversal Procedure

BestVasectomyReversalDoctorNYC1The 2008 report of the American Society for Reproductive Medicine cites current research indicating that microsurgical vasovasostomy results in sperm return to the semen in 85% to 90% of men and successful pregnancy in 50 to 70% of their partners. In men treated with microsurgical end-to-side vasoepididymostomy, sperm returns to the semen in 84% of men evaluated for 6 months or more, and 42% of men achieve pregnancy when evaluated for 12 months or more. When sperm do not return to the semen by 6 months after vasovasostomy or by 18 months after vasoepididymostomy, the reversal procedure has failed.

Success Rates Depend on Location of Vasectomy

Vasectomies which are performed closer to the testicle are more difficult to reverse and may require a vasoepididymostomy. A vas deferens that is disconnected further away from the testicle permits a reversal using the vasovasotomy technique which is known to have a higher success rate.

Success Rates Depend on Length of Time since Vasectomy

The more recent the vasectomy, the better is the prognosis for success in vasectomy reversal. Nevertheless, Dr. Larish has successfully reversed vasectomies in patients up to 40 years following a vasectomy with pregnancy occurring in as little as a few months after reversal.

Other Positive Indicators of Successful ReversalBestVasectomyReversalDoctorNYC5

A prior history of good fertility especially with the same partner, overall good health, and the presence of a “sperm granuloma” all increase the likelihood of success. A sperm granuloma acts as a pressure relief valve for the epididymis and keeps epididymal pressure low which decreases the risk of epididymal rupture. Epididymal rupture (“blowout”) would necessitate the vasoepididymostomy procedure known to be the less successful of the two types of reversal surgeries. The longer the vas deferens on physical exam, the lower is the risk of obstruction and the greater is the chance for a regular, more successful vasovasostomy procedure. However, the absence of epididymal blockage or vas deferens obstruction on exam cannot guarantee that a vasoepididymostomy will not be necessary.

Negative Indicators of Successful ReversalBestVasectomyReversalDoctorNYC4

A firm or enlarged epididymis on physical exam may represent epididymal blockage which mandates the more complicated, less successful vasoepididymostomy procedure. One or both testicles found to be small in size may indicate testicular failure and may negatively impact the success of reversal.

BestVasectomyReversalDoctorNYC3The Most Important Factor in Successful Vasectomy Reversal

Dr. Larish distinguishes between “patency” success rates and “pregnancy” success rates. Patency rates quantitate the success of sperm in returning to the ejaculate. Because pregnancy is a “couples phenomenon” and depends on other factors such as female fertility issues, its measurement is always lower than the patency rate. Please view the success rate of our vasectomy reversals for both the vasovasotomy and vasoepididymostomy procedures:

It is imperative that the chief surgeon be highly skilled in all aspects of urologic reconstruction but, most importantly, in the microscopic vasoepididymostomy procedure. Dr. Larish currently employs a state-of-the-art vasoepididymostomy approach. Also referred to as the longitudinal intussusception technique, it requires the microscopic manipulation of two 10-0 or 11-0 sutures (finer than a human hair). Dr. Larish’s expertise in this highly demanding procedure has resulted in a remarkable 90% patency rate in his vasoepididymostomy patients. These inspiring videos and testimonials affirm Dr. Larish’s masterful understanding of male fertility surgery.
