Sons Born with Fertility Treatment May Inherit the Same Problems

What the Research Found

A study by researchers at the Universiteit Brussel examined 54 men between the ages of 18 and 22 who were conceived using Intra-cytoplasmic Sperm Injection (ICSI) — a fertility treatment in which a single sperm is injected directly into an egg. These men were compared to 57 men of the same age who were conceived naturally.

The findings were significant:

• Men conceived using ICSI had half the sperm concentration in their ejaculate compared to naturally conceived men
• They also showed a two-fold lower total sperm count and motile sperm count

Motility refers to how well sperm can swim — a critical factor in natural conception.

The lead researcher, Prof. Richard Sharpe of the Male Reproductive Health Research Team at the University of Edinburgh, put it plainly:

"The results are a reminder to us that ICSI is not a treatment for male infertility, but simply a way of bypassing a problem and leaving it for the next generation to deal with."— BBC News | Prof. Richard Sharpe, University of Edinburgh

What This Means for Couples Considering ICSI

ICSI has helped millions of couples conceive. It is a valuable tool — but it is not a cure for male infertility. When the underlying cause of a man's reduced fertility is genetic or heritable, ICSI can allow that condition to be passed to a son, who may then face the same fertility challenges.

This does not mean ICSI is the wrong choice. For many couples, it remains the best available path to parenthood. But it does mean that proceeding with ICSI without first understanding why a man's fertility is reduced is an incomplete approach.

The Y Factor's Approach: Understanding the Cause First

At The Y Factor, we have been counseling patients on this issue for years. Before a couple proceeds with IVF and ICSI using partner sperm, it is important to identify the underlying cause of the male fertility problem — because that information changes the decision in front of them.

If the cause of decreased fertility is identified and found to be heritable, a couple may choose to:

• Proceed with partner sperm, fully informed of the possibility that a son may face similar fertility challenges
• Use banked donor sperm during the IVF ICSI cycle to avoid passing the condition to the next generation

Neither choice is wrong. But it should be an informed choice — made with a complete understanding of the situation, not a bypassed one.

Why Male Fertility Evaluation Matters Before IVF

Too often, the male partner receives minimal evaluation before a couple begins fertility treatment. A basic semen analysis is ordered, ICSI is recommended, and the process begins — without anyone asking why the sperm parameters are low in the first place.

At The Y Factor, a comprehensive male fertility evaluation goes beyond a semen analysis. We investigate the underlying cause of reduced sperm count, poor motility, or abnormal morphology — including genetic testing when clinically warranted. This gives couples the information they need to make a fully informed decision about their path to parenthood.
