Infertility

In biology, infertility is the inability of a male and female organism to reproduce. It is usually not the natural state of a healthy organism that has reached sexual maturity, so children who have not undergone puberty, which is the body's start of reproductive capacity, are excluded. It is also a normal state in women after menopause.

Mycoplasma is a genus of bacteria that, like the other members of the class Mollicutes, lack a cell wall (peptidoglycan) around their cell membrane.
