Azoospermia is the medical condition of a man whose semen contains no sperm.
Azoospermia factor (AZF) refers to one of several proteins or their genes, which are coded from the AZF region on the human male Y chromosome.
A base pair (bp) is a unit consisting of two nucleobases bound to each other by hydrogen bonds.
DAZ-associated protein 1 is a protein that in humans is encoded by the DAZAP1 gene.
Deleted in azoospermia 1, also known as DAZ1, is a protein which in humans is encoded by the DAZ1 gene.
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule.
Fertility is the natural capability to produce offspring.
Gel electrophoresis is a method for separation and analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size and charge.
A genetic disorder is a genetic problem caused by one or more abnormalities in the genome.
A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species.
Infertility is the inability of a person, animal or plant to reproduce by natural means.
Male infertility refers to a male's inability to cause pregnancy in a fertile female.
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.
Terms oligospermia and oligozoospermia refer to semen with a low concentration of sperm and is a common finding in male infertility.
Polymerase chain reaction (PCR) is a technique used in molecular biology to amplify a single copy or a few copies of a segment of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.
A semen analysis (plural: semen analyses), also called "seminogram" evaluates certain characteristics of a male's semen and the sperm contained therein.
A sequence-tagged site (or STS) is a short (200 to 500 base pair) DNA sequence that has a single occurrence in the genome and whose location and base sequence are known.
Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis.
Testis-specific Y-encoded protein 1 is a protein that in humans is encoded by the TSPY1 gene.
White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.
The Y chromosome is one of two sex chromosomes (allosomes) in mammals, including humans, and many other animals.
