Cryptorchidism in the horse can occur with either the left or right testis or with both testes. … Stallions with one retained testis and
one scrotal testis are usually fertile
since an adequate number of motile sperm are produced by the descended testis to get mares pregnant.
Can a cryptorchid horse reproduce?
This behavior may be caused by cryptorchidism. Cryptorchidism means that quite often, although
a horse cannot reproduce it still produces
testosterone and for that reason, the horse will act like a stallion.
Can cryptorchidism cause infertility in horses?
Cryptorchid
horses have lowered fertility
. TRUE. A stallion that only has one descended testicle only has one testicle to produce sperm, which automatically lowers the semen count for that stallion. “If you have a small book of mares, then you can compensate with that one testicle,” Espy said.
Does cryptorchidism affect fertility?
Cryptorchidism is associated with impairment of germ cell maturation and
subsequent infertility in adulthood
.
Is a unilateral cryptorchid sterile or fertile?
In unilateral cryptorchidism, the incidence of infertility may be as high as 32% and up to 59% of men with bilateral cryptorchidism may be
infertile
despite surgical correction by orchidopexy.
How do I know if my horse has Cryptorchid?
Signs and Symptoms: Cryptorchid horses usually
exhibit standard stallion behavior

What causes horse cryptorchidism?
Cryptorchidism in the horse can occur with either the left or right testis or with both testes. Failure of one or both testes to descend into the scrotum may be due to genetic predisposition,
insufficient androgen (i.e. testosterone) stimulation
, and other factors.
What happens if cryptorchidism is left untreated?
If not treated promptly, this might result in the
loss of the
testicle. Testicular torsion occurs 10 times more often in undescended testicles than in normal testicles. Trauma. If a testicle is located in the groin, it might be damaged from pressure against the pubic bone.
Can people with cryptorchidism have children?
How Much Does It Affect Fertility?

What are the signs of infertility in males?
- Problems with sexual function — for example, difficulty with ejaculation or small volumes of fluid ejaculated, reduced sexual desire, or difficulty maintaining an erection (erectile dysfunction)
- Pain, swelling or a lump in the testicle area.
- Recurrent respiratory infections.
- Inability to smell.
Which testicle is more important?
The
left testicle
is bigger than the right one; therefore, the left vein is longer than the right. Because the left vein is longer, it is subject to more difficulties when draining. Poor drainage can lead to pathological conditions such as testicular swelling and pain.
Can undescended testicle correct itself?
