Cryptorchidism, also known as undescended testis, is the failure of one or both testes to descend into the scrotum. The word is from Ancient Greek κρυπτός (kryptos) ' hidden ' and ὄρχις (orchis) ' testicle ' .
The most common presentation of testicular cancer is a hard, painless lump which can be felt on one of the testis. It is either noticed by a clinician during a routine examination, or the patient themselves. Risk factors for TC include cryptorchidism, family history, and previous testicular cancer. A diagnosis is confirmed in various ways.
The genetic mutational cause of PMDS, is a 27 base-pair deletion of the Anti-Müllerian Type 2 Receptor gene. The 27-base-pair deletion that occurs PMDS is in exon 10 on one allele. [ 9 ] With the AMHR2 gene mutation (PMDS Type 2), the AMHR2 is either not produced, produced in deficient amounts, defective, or the Müllerian ducts manifested a ...
Also known as cryptorchidism, undescended testicles occur when one or both testicles fail to fully migrate into the scrotum during development. It can lead to low testosterone, male infertility ...
Globally testicular cancer resulted in 8,300 deaths in 2013 up from 7,000 deaths in 1990. [9] Testicular cancer has the highest prevalence in the U.S. and Europe, and is uncommon in Asia and Africa. [67] Worldwide incidence has doubled since the 1960s, [68] with the highest rates of prevalence in Scandinavia, Germany, and New Zealand. [citation ...
Boys not treated for the condition may have fertility problems in later life and are at higher risk of testicular cancer. Pollution from coal mining and metal works ‘may be linked to ...
A cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predisposes the affected individuals to the development of cancers and may also cause the early onset of these cancers. Although cancer syndromes exhibit an increased risk of cancer, the risk varies.
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 .
