Male infertility refers to a sexually mature male's inability to impregnate a fertile female.
Men with this condition may exhibit azoospermia (no sperm production), oligozoospermia (small number of sperm production), or they may produce abnormally shaped sperm (teratozoospermia).
Elective surgical procedure for male sterilization or permanent contraception.
After a vasectomy, contraceptive precautions must be continued until azoospermia is confirmed.
Having more body fat than is optimally healthy.
Being overweight also increases the risk of oligospermia and azoospermia in men.
Discharge of semen from the male reproductory tract as a result of an orgasm.
An unusually low sperm count, not the same as low semen volume, is known as oligospermia, and the absence of any sperm from the semen is termed azoospermia.
Inability of a person, animal or plant to reproduce by natural means.
Affected individuals displayed more severe forms of infertility such as azoospermia and severe oligozoospermia.
Genetic disorder that affects mostly the lungs, but also the pancreas, liver, kidneys, and intestine.
The main cause of infertility in men with CF is congenital absence of the vas deferens (which normally connects the testes to the ejaculatory ducts of the penis), but potentially also by other mechanisms such as causing no sperm, abnormally shaped sperm, and few sperm with poor motility.
A semen analysis (plural: semen analyses), also called seminogram or spermiogram, evaluates certain characteristics of a male's semen and the sperm contained therein.
A vasectomy is considered successful if the sample is azoospermic (zero sperm of any kind found).
In vitro fertilization (IVF) procedure in which a single sperm cell is injected directly into the cytoplasm of an egg.
Additionally, specialists use ICSI in cases of azoospermia (when there are no spermatozoa ejaculated but they can be found in testis), when valious spermatozoa (the name given to sperm samples taken to preservate fertility afer chemotherapy) is available, or after previous irruptions in IVF cycles.
Activin and inhibin are two closely related protein complexes that have almost directly opposite biological effects.
In men with azoospermia, a positive test for inhibin B slightly raises the chances for successfully achieving pregnancy through testicular sperm extraction (TESE), although the association is not very substantial, having a sensitivity of 0.65 (95% confidence interval [CI]: 0.56–0.74) and a specificity of 0.83 (CI: 0.64–0.93) for prediction the presence of sperm in the testes in non-obstructive azoospermia.
Disorder characterized by male sterility without sexual abnormality.
Sertoli cell-only syndrome is like other non-obstructive azoospermia (NOA).
