Does a Varicocele Always Affect Fertility?
Posted on May 17, 2025 by root

Varicoceles are an often overlooked yet significant concern in male reproductive health. A varicocele is essentially an enlargement of the veins within the scrotum, which can have various implications for fertility and overall male health. As a leading expert in this field, Dr. Justin Houman, a board-certified urologist and fellowship-trained Men’s Sexual and Reproductive Health specialist in Los Angeles, CA, explores what varicoceles are, when they can affect fertility in men and the available treatment options.
What is a Varicocele?
A varicocele occurs when the valves within the veins of the scrotum malfunction, causing blood to pool and the veins to swell. The Urology Care Foundation™ reports that these unpleasant yet common occurrences can be found in nearly 15% of the male population and are especially prevalent among men aged 15 to 25, often developing over time. About 10 to 15 boys out of 100 have a varicocele. It is like getting a varicose vein in your leg.
While most men with varicoceles may not experience any significant symptoms, some may notice discomfort, swelling or a feeling of heaviness in the scrotum.
Do Varicoceles Affect Fertility?
One of the primary concerns surrounding varicoceles is their potential impact on fertility. The National Institutes of Health reports that approximately 40% of men with infertility issues have varicoceles, making them one of the leading causes of male infertility.
The underlying mechanisms include:
- Temperature Regulation: The scrotum is designed to maintain optimal temperatures for sperm production. Varicoceles can elevate scrotal temperature, impairing sperm development and function.
- Hormonal Changes: Varicoceles can lead to hormonal imbalances, particularly in testosterone levels, which play a crucial role in sperm production and male reproductive health.
- Sperm Quality: Research has shown that men with varicoceles often have lower sperm counts and poorer sperm motility, making it more challenging to achieve pregnancy.
The November 2012 Asian Journal of Andrology found that varicoceles are present in 75% of men with secondary infertility.
When Is Treatment Necessary?
Not every varicocele requires treatment. A varicocele may not have any noticeable symptoms or impact on fertility for many men. However, if a couple is experiencing difficulties conceiving, evaluating the presence and severity of a varicocele is essential. Dr. Houman recommends that men undergo an assessment if they:
- Have been diagnosed with infertility.
- Experience discomfort or pain in the scrotal area.
- Notice changes in testicular size or feel a noticeable lump.
In such cases, a consultation with a specialist is crucial for determining the best course of action.
Microsurgical Varicocelectomy in Los Angeles
At Dr. Justin Houman’s practice in Los Angeles, various treatment options for managing varicoceles are available, tailored to meet each patient’s needs. As a minimally invasive microscopic surgeon, Dr. Houman specializes in microsurgical varicocelectomy to help men with fertility issues and other problems caused by varicoceles.
This is the gold standard for treating varicoceles that impact fertility. Through a small incision, Dr. Houman uses a microscope to precisely identify and ligate the affected veins. The June 2023 World Journal of Men’s Health published the findings of a review on a wide array of literature and studies concerning varicocele repair to aid in fertility, and the available research showed significant improvements in all semen parameters after varicocele repair.
Studies published in the January 2010 Journal of Urology® indicate that microsurgical varicocelectomy can significantly improve sperm parameters, with success rates of restoring fertility approaching 50-70%.
Plus, the procedure is:
- Minimally Invasive – Precision technique using a high-powered surgical microscope
- Faster Recovery – Short downtime with minimal post-op discomfort
- Lower Recurrence Rate – Less than 1% recurrence compared to other methods
Other Treatment Options
Other treatments may be recommended if a varicocelectomy is not best for you. These can include:
Embolization
This minimally invasive procedure involves blocking the affected veins using a catheter and coils. The recovery time is shorter than that of surgical options, making it a suitable alternative for some patients.
Hormonal Therapy
If hormone imbalances are a concern, Dr. Houman may recommend hormonal therapies to improve sperm production and overall reproductive health.
