Background about male fertility and sperm problems

About 25% of all infertility is caused by a male problem, and in 40-50% of cases it is the main cause, or a contributing cause.

It is sometimes hard to know whether the male factor problem is the only cause, or just a contributing cause to the infertility. Part of the problem is that numbers are just numbers:

What matters is not really how many or how fast they swim - but whether they can fertilize the female partner's eggs. This is really a biochemical issue at the molecular level.

Therefore, looking at the little swimmers under the microscope is not always a perfect way of assessing the ability of the sperm to fertilize the female's eggs.


Semen analysis - check the sperm count, motility and morphology

This is a very simple and important test and should be done early in the evaluation process. Sometimes the test should be done 2, or even 3 times to get an accurate reflection of the numbers and their variation over time.

The most important parameters in a semen analysis are:

  1. Concentration (often called "count") - how many sperm are in each ml of semen?
  2. Motility - what percent of them are swimming forward?
  3. Morphology - what percent of them are normally shaped?

Cutoff values for normal vary somewhat, depending on the lab and the interpreter.

  • The World Health Organization's 5th edition of "normal semen analysis" values are shown below
Semen Analysis Parameter Normal Values
Volume 1.5 ml or more
pH > or equal to 7.2
Sperm concentration 15,000,000/ml or more
Total motility 40% or more
Progressive motility 32% or more
Morphology 4% or more normal forms (Strict criteria)
Vitality 58% or more live
White blood cells Less than 1,000,000/ml

If a severe male factor defect is found, the amount of testing on the female is often reduced. Treatments, such as inseminations or in vitro fertilization can then be started more directly.

Further testing on the male with an abnormal semen analysis

In some cases we do hormone (blood) tests on men with abnormal semen analysis. This can (rarely) sometimes identify a reason for the abnormality. Occasionally, the problem will be treatable in the male.


Sperm function tests

Sperm penetration assay, also called the hamster egg test

The sperm is mixed with hamster eggs to see whether they penetrate the eggs. It is expensive and there are many false positives and also false negative results. Some men are better with the hamster than with his partner... etc. We do not do this test.

Human zona binding assay: In this test, sperm is mixed with pieces of human egg shells (zona pellucidas) to see how many will bind to the shells. There are a lot less false positives and false negative results as compared to the hamster egg test. However, human egg shells are not readily available - so it is not a practical test.


Sperm antibody testing

  • Sperm antibodies in the blood of men or women do not affect fertility
  • Antibodies on the head of the sperm can cause failure of fusion with the egg
  • Spontaneous pregnancy rates are higher in couples without these antibodies. However, fluctuations are seen even without therapy.
  • Also, since inseminations are used as treatment for both unexplained infertility and for sperm antibodies, some fertility specialists don't find this test very useful.
  • Antibody testing can help determine whether sperm should be injected into the eggs if the couple does in vitro fertilization.

Varicocele

In some cases the man is referred to a urologist to assess whether he might have a correctable condition called a varicocele. However, correcting a varicocele (surgical procedure) often does not improve the semen quality enough to change the therapy that will be required to result in pregnancy.

  • In other words, if a couple will need IVF and ICSI anyway, why do varicocele surgery?
  • The best treatment option depends on the degree of abnormality in the semen and other factors, such as the age of the female partner, results of her ovarian reserve testing, etc.

TESTIMONIALS

profile

I am so grateful for Advanced Fertility Center. I just had my son Leland. I want to thank Dr. Catenacci and all of the nurses that helped us. Especially Ashley in the Crystal Lake office. You made this process easier by being supportive and positive. Thank you very much!

profile

Dr. Sherban and his staff are the most amazing, compassionate, and supportive people. After almost 5 years of trying to conceive, going through numerous tests and meeting with another clinic closer to home, who told me my chances even with IVF were still very low, a good friend recommended advanced fertility center of Chicago. Best decision we ever made! We now have 2 amazing children who are now 5 and 3 years old! I cannot stress enough how amazing this staff is, they make you feel like family!

Our experience was amazing with Dr. Cantanucci and all of the nurses (especially Ashley). After ttc for 4 years and at 41 years of age, we became pregnant after 1 round of IVF, and had our beautiful boy this past October. Can't thank them enough!

2/7/15 our son was born all thanks to the assistance of Dr. Sherbahn and his staff. Everyone was so helpful and here for all our questions, worries, etc. They want this for you just as much as you want this for you! Handled with pure professionalism and care from the very start! Thank you advanced fertility!
