No, although oligospermia refers to the low concentration of spermatozoa, they are present in the ejaculate. Azoospermia is the absence of spermatozoa in the ejaculated semen, and invasive techniques are necessary for their recovery, such as epididymal aspiration, testicular puncture or biopsy.
Is 'oligospermia' the same as 'azoospermia'?
