• malformations of the male excretory system
  8 March 2010

  Congenital malformations of the male excretory system are usually
  asymptomatic and are diagnosed incidentally later in life following orchidopexy
  and/or surgical exploration for hydroceles and inguinal hernias or during
  evaluation for infertility.
  Well-recognized congenital epididymal malformations include anomalous attachment of the epididymis to the testis and anomalies of number, size and location (such as agenesis, duplication, hypoplasia and ectopia).
  Anomalous attachment (...)

• paratesticular mucinous cystadenoma
  22 October 2009

  Mucinous cystadenomas of the testis and paratestis are extremely rare benign tumors of controversial origin.
  The diagnosis may be challenging and is of clinical importance because these lesions may mimic a teratoma, and teratomas in postpubertal males carry a malignant potential regardless of the degree of maturation.
  A few case reports and reviews of testicular and paratesticular mucinous neoplasms resembling ovarian tumors have suggested the possibility of a müllerian origin of these (...)

• unilateral cryptorchidism
  8 June 2009

  Unilateral cryptorchidism is frequently accompanied by infertility.
  Uncertainty exists as to whether the infertility is a genetic effect or is related to an autoimmune reaction to the elevated testis.

• complete androgen insensitivity syndrome
  8 June 2009

  CAIS
  The androgen insensitivity syndrome (AIS) is caused by a defect in the androgen receptor (AR) gene, which results in com­plete (CAIS) or partial (PAIS) androgen insensiti­vity with variable phenotypic expression.
  The androgen insensitivity syndrome (AIS) is a rare (approximately 1:20,000 male births), X-linked disorder characterized by 46,XY karyotype, pres­ence of normal testes and normal androgen produc­tion and metabolism.
  While in­dividuals with CAIS have female external genitalia (...)
