a condition whereby a man produces little or no sperm.
The disorder where the ejaculated semen does not contain any sperm cells; this may be due to a blockage (as in vasectomy) or a failure in production of the sperm. to top of page
This is when there is no sperm in the semen.
The absence of sperm in the seminal fluid due to a blockage in the sperm ducts or poor sperm production
Absence of sperm in the semen; it can be caused by failure of testis to produce sperm in the seminferous tubules, or by obstruction of vas deferens ( Ducts leading sperm out of testis to urethra).
absence of living sperm in semen, which is a sign of male infertility.
A condition in which semen produces no sperm. close window
An absence of sperm in the ejaculate.
The absence of sperm in seminal fluid due to blockage of sperm ducts or impairment of sperm production.
Absence of sperm in ejaculate. Obstructive Azoospermia: The result of obstruction in either the upper or lower male reproductive tract (epididymis, vas deferens, seminal vesicles or ejaculatory ducts). Sperm production may be normal (which may be verified through testicular biopsy), but the obstruction is preventing the sperm from being ejaculated. Some causes of obstructive azoospermia are vasectomy, congenital absence of vas deferens, scarring from past infections, and hernia operations. Non-obstructive Azoospermia: Severely impaired or non-existent sperm production. Some sperm may be found and extracted directly from the testicles.
The absence of sperm in the ejaculate.
the absence of spermatozoa in the semen or failure of formation of spermatozoa.
The complete absence of sperm from the semen.
Semen containing no sperm, either because the testicles cannot make sperm or because of blockage in the reproductive tract.
the absence of sperm in an ejaculate.
When a man has no sperm present in his semen.
The absence of sperm in the seminal fluid. This may be due to a blockage or an impairment of sperm production.
The complete absence of sperm in the semen. l J l l N l l Q l l l X l Y l
complete absence of sperm in seminal fluid.
Total absence of sperm in the ejaculate.
This is the absence of spermatozoa but presence of cells of spermatogenesis.
The absence of sperm in the seminal fluid, usually caused by a blockage or an impairment of sperm production.
A complete absence of sperm (spermatozoa) in the semen. Detectable only by performing a sperm count, as semen looks the same whether it contains sperm or not. Due either to an obstruction (usually in the epididymis or vas deferens), and called obstructive azoospermia, or to failure of sperm to form or to mature in the testis (called maturation arrest). See also spermatogenesis and testicular sperm extraction (TESE).
Azoospermia is the medical condition of a man not having any measurable level of sperm in his semen. It is associated with very low levels of fertility.
