A microscopic semen analysis will reveal aspermia/azoospermia. 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.
A urine specimen may be collected, and is likely to demonstrate blood within the urine. [9] Laboratory examination of seminal vesicle fluid requires a semen sample, e.g. for semen culture or semen analysis. Fructose levels provide a measure of seminal vesicle function and, if absent, bilateral agenesis or obstruction is suspected. [13]
Hematospermia (also known as haematospermia, hemospermia, or haemospermia) is the presence of blood in the ejaculate. It is most often a benign symptom. [1] Among men age 40 or older, hematospermia is a slight predictor of cancer, typically prostate cancer. [2] No specific cause is found in up to 70% of cases.
The most common reasons for laboratory semen analysis in humans are as part of a couple's infertility investigation and after a vasectomy to verify that the procedure was successful. [4] It is also commonly used for testing human donors for sperm donation, and for animals semen analysis is commonly used in stud farming and farm animal breeding.
Kidney stone disease, also known as renal calculus disease, nephrolithiasis or urolithiasis, is a crystallopathy where a solid piece of material (renal calculus) develops in the urinary tract. [2] Renal calculi typically form in the kidney and leave the body in the urine stream. [2] A small calculus may pass without causing symptoms. [2]
Factors contributing to stone formation (as in #Etiology) are often tested: Laboratory testing can give levels of relevant substances in blood or urine; Some stones can be directly recovered (at surgery, or when they leave the body spontaneously) and sent to a laboratory for analysis of content
Leucospermia – a high level of white blood cells in semen; Normozoospermia or normospermia – It is a result of semen analysis that shows normal values of all ejaculate parameters by WHO but still there are chances of being infertile. This is also called as unexplained Infertility [citation needed]
Kidney stones (nephrolithiasis) are a relatively common and particularly painful disorder. A chronic condition can result in scars to the kidneys. The removal of kidney stones involves ultrasound treatment to break up the stones into smaller pieces, which are then passed through the urinary tract. One common symptom of kidney stones is a sharp ...
