Castration of the undescended teste(s) should be considered for cryptorchid dogs due to the high rate of testicular cancer, especially Sertoli cell tumors. [23] The incidence of testicular cancer is 13.6 times higher in dogs with abdominally retained testicles compared with normal dogs. [19] Testicular torsion is also more likely in retained ...
A ridgling (also spelled ridgeling), [1] or rig, is a cryptorchid; [2] a male animal with one or both testicles undescended, [1] usually describing a ram, bull, or male horse, [3] but cryptorchidism also can be an issue in dogs and cats. [4] Because the heat inside the body is too high for sperm to survive, an undescended testicle is non ...
PMDS Type I is also referred to as hernia uteri inguinalis, which exhibits one descended testis that has also pulled the fallopian tube, and sometimes uterus, through the inguinal canal. [8] The descended testes, fallopian tube and uterus all fall in the same inguinal canal, causing an inguinal hernia. [ 8 ]
Raveenthiran described a new syndrome in which Spigelian hernia and cryptorchidism (undescended testis) occur together. [16] Some common complications of this distinct syndrome cryptorchidism are testicular torsion, and its link to testicular cancer. [17]
Undescended testis is found in 4% of full-term infants but only 0.8% of males at the age of 1 year have true cryptorchidism. Although an undescended testis can be found anywhere along the pathway of descent from the retroperitoneum to the scrotum, the inguinal canal is the most common site for an undescended testis.
Diagnosing undescended testicles involves a physical examination. If the testis cannot be felt, it is categorized as "non-palpable." Generally, there are three underlying reasons for nonpalpable testicles: The testis is in the inguinal canal but cannot be palpated for specific reasons. The testis is situated inside the abdomen.
Polyorchidism can also occur in conjunction with infertility, inguinal hernia, testicular torsion, epididymitis, hydrocele testis and varicocele. [4] However, it is not clear whether polyorchidism causes or aggravates these conditions, or whether the existence of these conditions leads sufferers to seek medical attention and thus become ...
One testicle not descending into the scrotum during normal embryonic or fetal development (3–4% of 'normal' live births), also known as undescended testis or cryptorchidism. In this case the testis is within the abdominal cavity, somewhere along the normal route of descent – most commonly, within the inguinal canal.
