Does one sided cryptorchidism cause infertility in men? Does a man with one healthy testicle have a lower sperm count?

Does one sided cryptorchidism cause infertility in men? Does a man with one healthy testicle have a lower sperm count?

Likely fertile: Sperm count will probably be within normal limits because remaining testicle will grow larger (compensatory hy[pertrophy) and thus produce more sperm than if it were 1 of a pair, but count may be slightly reduced. Semen volume is unaffected and normal because >95% is produced by the seminal vesicles, prostate and cowper's glands. Sperm is no > 5% of ejaculate. ...Read more

Is it normal to have 1"x1/2" left testicle? Twice as small as the right. What could be the cause of this? Could this cause low sperm count?

Is it normal to have 1"x1/2" left testicle? Twice as small as the right. What could be the cause of this? Could this cause low sperm count?

No, not normal: Average testicle size after puberty is ~2" long, 0.8" width, and 1.2" height (5 x 2 x 3 cm). Causes of a small (atrophic) testicle include: 1) painful conditions like torsion, infection, and severe trauma, and 2) painless conditions like the presence of a varicocele, abnormal development, genetic anomaly, prior surgery affecting blood flow, steroids, etc. Depending on cause, could affect fertility. ...Read more

Azoospermia: Azoospermia is defined as the complete lack of sperm in the ejaculate. It occurs in 5% of infertile men. If this is the case, then one or both of two conditions may be present (“causes”): There is a problem with sperm production or there is a blockage such that sperm production, although normal, cannot reach the ejaculate. If truly no Sperm, then he cannot have children. Get eval with fertility dr ...Read more

Can it mean that you have a low sperm count if your testicles look drained?

Can it mean that you have a low sperm count if your testicles look drained?

Get a Semen Analysis: You can't tell by looking at your testicles. Semen analysis is best done through a fertility clinic or urology office rather than a general medical testing lab. Home sperm tests are not very useful. If you're not trying to conceive assume you're fertile; if you and your partner are trying to conceive you should both see a fertility specialist (rei) for testing and individualized treatment. ...Read more

I had an undescended testicle as a youth, but my other testicle was fine, I had a test done with negative sperm count, could the bad testicle be problem?

I had an undescended testicle as a youth, but my other testicle was fine, I had a test done with negative sperm count, could the bad testicle be problem?

No sperm: If there are no sperm, both testicles are the problem. Usually the undescended testicle is removed? I would check in with a urologist or fertility expert to sort through your dilemma. All the best. ...Read more

If a man had a testicle remove because of a benine tumor and is now on Clomid (clomiphene) with zero sperm count how long before u see any sperm or if any?

Unusual: Removing a testicle should not affect the sperm count. The other testicle should produce plenty of sperm. So there is another problem. Either there is an obstruction and surgery is required or there is a sperm production problem. He would need an evaluation by a urologist experienced in fertility. ...Read more

Hi does zma (zinc magnesium vitaminb6) helps increase sperm count a can help to testicles regain they size if they were shrunk?

Hi does zma (zinc magnesium vitaminb6) helps increase sperm count a can help to testicles regain they size if they were shrunk?

Nothing can...: The odd to improve sperm count by an individual nutrient is unclear and remains in doubt. In addition, no food or nutrient can help regain testicular size since physical growth naturally stops soon reaching adulthood, which is attained at about age 18 for men. Thereafter, we have to adopt and adapt what we have grown to. More? Contact me and I can help. ...Read more

My cat sat in my lap, he was warm...can that affect my testicles, in terms of testosterone production or sperm count?

No: The testicles will do what the testicles will do, whether there is a cat in the lap. Likewise, the cat will do what the cat will do, regardless of the presence or absence of testicles. Testicles and cats don't have a noticeable effect on one another. ...Read more

Doc my left testicle look really weird like it sits up a little higher than the other one but I felt my sperm cord and it doesn't feel twistedDX?

Doc my left testicle look really weird like it sits up a little higher than the other one but I felt my sperm cord and it doesn't feel twistedDX?

Probably normal: This doesn't sound abnormal. At age 16 you're just learning, but in mature men one testicle almost always hangs lower (usually the left, but it can be either one). If testicular torsion (twisted sperm cord) you would be in escrutiating pain and would need to see a urologist immediately for emergency surgery. If no pain, probably no problem. But ask your doctor next time you're in the office. ...Read more

What cell types make up the majority of a testicle? Sperm? Sertoli? Leydig? Also, could you give approximate %s?

Testicles: Lydig Cells are the most prevalent in terms of numbers
Curtail cells are less but bigger. The functions of each are different and in terms of total function, it is irrelevant what percentage of cells is higher than the other. Sperm cells are produce in the tubules of the testicles.

What cells make up the majority of a testicle? Isn't it the sertoli/sperm cells? Aren't the leydig just a small percentage?

Correct: The seminiferous tubules and sperm-producing cells make up about 90% of the testicular volume. The Sertoli cells which help support sperm production and the Leydig cells which produce >90% of the body's testosterone make up <5% of testicular volume and the remainder consists of blood vessels and connective tissue. ...Read more
