Definitions for "Oligospermia"
deficiency of spermatozoa in the semen
the steroid hormone secreted by the ovary mainly from the corpus luteum. It is essential for nidation of the ovum and maintenance of pregnancy; cessation of its secretion at the end of the menstrual cycle largely determines the time of onset of menstruation. The hormone, now obtained by synthesis, is used for the management of various ovarian disorders.
Strictly, oligozoospermia, meaning a reduced number of sperm cells (spermatozoa) in the ejaculate (compared with azoospermia, which means no sperm in the ejaculate). More generally, a decrease in normal, motile sperm, and more or less encompassing laborious terms such as 'asthenozoospermia' (weak motility) and 'teratozoospermia' (abnormal sperm), and even more laborious ones, such as 'oligoasthenoteratozoospermia', which do not reward the effort of concocting them.
