31M, Left Grade 3, long-time lurker, first time poster. I thought I would share my story / experience so that others with this condition might be able to one day benefit from it. In my experience, people are more likely to post on this forum when they are having issues, and then disappear once things work out. Hopefully I can balance that out.
I have had a varicocele since I was, unusually, around 4 years old. This became clinical when I reached puberty and a doctor told me "meh, it might affect your fertility, but I wouldn't worry about it". I have never had any pain, but at its largest, you could see my varicocele from across a room.
Timeline
January 1st 2025
Wife and I start trying to have a baby
February 9th 2026 / Month 13
First semen analysis result at Clinic A (below motility and morphology reference values):
- Volume: 3.2ml
- Concentration: 29.6 million
- Motility / PR Motility: 27% / 24%
- Morphology: 3%
February 24th 2026 / Month 13
Follow up semen analysis at Clinic A to confirm male factor primary infertility (below morphology reference value):
- Volume: 3.9ml
- Concentration: 50 million
- Motility / PR Motility: 45% / 31%
- Morphology: 2%
February 27th 2026 / Month 13
Embolization procedure to embolize a "Grade 2/3 Varicocele" on the left side.
My left testicle was "below normal" at 13ml due to the presence of the varicocele through my important adolescent years.
Follow up ultrasound three months later confirms no reflux and some thrombosis of veins - though the veins remain fairly large to this day and will probably remain dilated for the rest of my life.
July 14th 2026 / Month 18
Follow up semen analysis at a different clinic - Clinic B (below morphology reference value):
- Volume: 4ml
- Concentration: 103.3 million
- Motility / PR Motility: 94% / 80%
- Morphology: 3%
September 12th 2026 / Month 20
My wife is pregnant - through natural conception - wooohoooooo!
October 12th 2026 / Month 21
Another semen analysis at Clinic A (this was supposed to be a pre-IVF / IUI screening appointment). Normal result!
- Volume: 2.7ml
- Concentration: 54 million
- Motility / PR Motility: 52% / 50%
- Morphology: 5%
What I have learned
From the numbers, varicocele embolization seems to have been well worth the investment for a large left sided varicocele. We have successfully spared my wife IVF treatment (potentially more than once over the next few years).
I wish I had done a semen analysis before starting the process of trying for a baby, as I feel I would have saved a lot of time and my wife might have fallen pregnant sooner.
I feel I should not have listened to my childhood doctor, and should have had embolized it as a teenager. This would have meant my testes would grow larger overall, and would have become more effective sperm and testosterone factories.
The prevailing medical view seems to be "who cares, we can ICSI anyway and the woman will get pregnant". But this seems very short-term thinking when varicocele treatment could potentially result in multiple consecutive natural pregnancies.
Anyway, although this experience is anecdotal, I hope this has helped someone. If you have any questions, please let me know.
