Male factor infertility
Male factor infertility Condition in which a male patient is infertile for such reasons as very low sperm count, sperm that cannot swim properly, sperm that are unable to penetrate the egg, or blocked sperm ducts.
RELATED TERMS--------------------------------------
Condition
The term "condition" has a number of biomedical meanings including the following: 1.An unhealthy state, such as in "this is a progressive condition." 2.A state of fitness, such as "getting into condition." 3.Something that is essential to the occurrence of something else; essentially a "precondition." 4.As a verb: to cause a change in something so that a response that was previously associated with a certain stimulus becomes associated with another stimulus; to condition a person, as in behavioral conditioning.
Sperm
A sperm cell, or spermatozoon (pl. spermatozoa) (in Greek: sperm = semen and zoon = alive), is the haploid cell that is the male gamete. It is carried in fluid called semen, and is capable of fertilising an egg cell to form a zygote. A zygote can grow into a new organism, such as a human. Sperm cells contain half of the genetic information needed to create life. Generally, the sex of the offspring is determined by the sperm, through the chromosomal pair "XX" (for a female) or "XY" (for a male).
Egg
The mature female reproductive cell.

Methylation
A biochemical process involving the addition of chemical tags called methyl groups (-CH3) to DNA. Methylation can be a signal for a gene or a section of a chromosome to turn off gene expression and become inactive or "silent".
Minor H antigens
Or minor histocompatibility antigens. A group of proteins (in addition to those encoded by the major histocompatibility complex (MHC) that can cause transplant tissue rejection. Minor H antigens can cause tissue rejection even when donor and recipient are matched for MHC. Immune response to minor H antigens is far less potent than response to MHC-encoded proteins, so the rejection is a slower process.
Mitochondrial heteroplasmy
An atypical condition characterized by the presence of more than one type of mitochondrial DNA in a single individual. Normally, each individual has only one type of mitochondrial DNA, inherited from his or her mother through the egg at fertilization. (Mitochondria from the sperm are systematically eliminated by the egg at fertilization.)Cloned organisms may exhibit mitochondrial heteroplasmy (having a mixture of mitochondria from both the donor cell and the recipient egg) because this elimination system may be bypassed during the cloning process.
Mitochondrion
Plural: mitochondria. A cellular structure in the cytoplasm that provides energy to the cell. Each cell contains many mitochondria. In humans, a single mitochondrion contains 37 genes on a circular mitochondrial DNA, compared with about 35,000 genes contained in the nuclear DNA.
Monozygotic twins
Twins derived from one egg and one sperm (often called identical twins).
