aspermia การใช้

• Aspermia can be caused by androgen deficiency.
• One of the causes of aspermia is retrograde ejaculation, which can be brought on by excessive drug use, or as a result of prostate surgery.
• "' Aspermia "'is the complete lack of semen with ejaculation ( not to be confused with azoospermia, the lack of sperm cells in the semen ).
• Ejaculatory duct obstruction may result in a complete lack of semen ( aspermia ) or a very low-volume semen ( oligospermia ) which may contain only the secretion of accessory prostate glands downstream to the orifice of the ejaculatory ducts.
• Another cause of aspermia is ejaculatory duct obstruction, which may result in a complete lack of or a very low-concentration semen ( oligospermia ), in which the semen contains only the secretion of accessory prostate glands downstream to the orifice of the ejaculatory ducts.
• In contrast, if both vasa deferentia are obstructed ( which may be the result of intended sterilization ), a semen analysis will also reveal aspermia / azoospermia, but an almost normal volume of the semen, since the efflux of the seminal vesicles is not hindered.
• If the seminal-vesicles contain spermatozoa, but the semen does not, the obstruction must be downstream of the seminal vesicles and the ejaculatory ducts are very likely to be obstructed, provided that other causes for a dry ejaculation / aspermia such as an retrograde ejaculation are ruled out.
