Has anybody been Fertility tested when younger?

In another thread discussing abstinence from ejaculation (https://en.zity.biz/index.php?mx=forum;ox=display;topic=129813) there were a few posts on fertility testing. This has made me wonder whether anyone else had their fertility checked as a teenage / young adult; and what the reasons for this were.

For me, I was knocked off my bicycle in my late teens and while in hospital my testicles painfully swelled massively. During other scans (suspected pelvic fracture) they noticed that I had tears / bleeding in my testicles. Eventually the sewlling subsided & they believed the bleeding had stopped. Before allowing me home, the doctor informed me he was slightly worried my fertility might be affected and requested a semen sample. After painfully producing 2 samples (first unusable due to amount of blood), he informed me that while I did have sperm in the sample, I was "sub-fertile". He suggested monitoring me over the next year to see what happened. It was a very strange feeling going to the fertility clinic where older couples were waiting for appointments (presumably struggling to conceive), while I was there as a single teenager. By the end of the year of monitoring, he informed me that while the amount of sperm had improved, I would still probably struggle with natural conception 😢. Later, when in a long-term relationship, I underwent repeat tests and was still informed in had borderline infertility. Oddly, in both cases I wasn't given any advice on any actions I could / should be taking to try and improve the situation.

Has anyone else undergone fertility testing at a younger age; and are you willing to share reasons and any treatment / outcomes?

Had a urologist order a sperm sample for a varicocele when I was 17 but I never did it. I just had the ultrasound done which confirmed it was a varicocele.

I had fairly extensive fertility testing starting at about age 27, and had a total of 7 semen analyses over a period of 15 years, in addition to several detailed examinations of my penis and scrotum by several different urologists. I was never found to be infertile, was checked since my wife had previously had her tubes tied and we were attempting to get pregnant after reversal surgery. She ultimately had two tubal pregnancies, so that was that. I did enjoy the evaluation process, which also included a post-coital test and a hamster egg test using one of the semen samples.
