Azoospermia is the medical condition of a man whose semen contains no sperm. [1] It is associated with male infertility, but many forms are amenable to medical treatment.In humans, azoospermia affects about 1% of the male population [2] and may be seen in up to 20% of male infertility situations in Canada.
Young's syndrome, also known as azoospermia sinopulmonary infections, sinusitis-infertility syndrome and Barry-Perkins-Young syndrome, is a rare condition that encompasses a combination of syndromes such as bronchiectasis, rhinosinusitis and reduced male fertility.
Sertoli cell-only disease is frequently characterized by azoospermia which is the complete absence of sperm in semen. A tiny fraction of patients may still have measurable sperm levels. A tiny fraction of patients may still have measurable sperm levels.
[10] [11] In a random international sample of 11,548 men confirmed to be biological fathers by DNA paternity testing, the oldest father was found to be 66 years old at the birth of his child; the ratio of DNA-confirmed versus DNA-rejected paternity tests around that age is in agreement with the notion of general male infertility above age 65–66.
The use of radiotherapy can cause a temporary bout of azoospermia, this however, is dependant solely on the nature of the dose that are delivered to the testes. Those who experience less than 100 rads will recover in 9–18 months, doses of 200-300 rads will recover in 30 months and doses of 400-600 rads will recover in less than or equal to five years.
The AZF1 (Azoospermia Factor 1) gene is likely located in the euchromatic part of the long arm in Yq11.23. AZF1 is 792kb long and just distal to the centromere of the Y chromosome. [8] AZF1 genes are involved in spermatogenesis in the testes. Common phenotypic manifestations of deletions in this region are azoospermia and Sertoli cell-only ...
