Azoospermia

Azor Matusiwa

Azoospermia is the medical condition of a man whose semen contains no sperm. It is associated with infertility, but many forms are amenable to medical treatment. In humans, azoospermia affects about 1% of the male population and may be seen in up to 20% of male infertility situations.

An azotosome (classical compound of "azote", French for nitrogen, and "soma", Greek for body) is a theoretical membrane that could possibly serve as the basis for a cell membrane of a hypothetical methane–ethane-based living cell, analogous to the phospholipid bilayers found in all water-based life on Earth.

An azotosome (classical compound of "azote", French for nitrogen, and "soma", Greek for body) is a theoretical membrane that could possibly serve as the basis for a cell membrane of a hypothetical methane–ethane-based living cell, analogous to the phospholipid bilayers found in all water-based life on Earth. Unlike a phospholipid-based cell membrane, an azotosome is composed of chemicals found in the methane–ethane liquid seas and in the atmosphere of Saturn's moon Titan, and it is capable of functioning in these conditions as a membrane. Thus far, azotosomes have only been computationally modeled, and have not been observed experimentally.
