Semen is a whitish or greyish liquid, but can occasionally appear yellowish,

Emitted from the urethra (tube in the penis) on ejaculation.

Normal Sperm Count Morphology Motility 20 to 150 million/ml

Sperm count below 20 million/ml called Oligospermia.

When a Sexologist (Sex Doctor),advices Semen Analysis of a patient then the patient is require to give the sample for this.

The sample should be collected after 3-4 days of sexual abstinence.
Typically, semen collection will require masturbation and collection of the semen into a sterile container.
Anyone who is having trouble conceiving should have a semen analysis done. In about 40% of infertile couples, the cause of the infertility lies with the males, and this could easily and quickly be diagnosed via a semen analysis.

The various parameters tested are:

Semen volume
Sperm concentration
Sperm count
Percentage motile sperm
Grade of motility
Normal sperm morphology

Semen consists of the secretions of several glands but only 5 per cent comes from the testicles, the remaining part comes in this way:-

46 to 80 per cent of semen comes from Seminal vesicles, 13 to 33 per cent comes from Prostate gland , glands2 to 5 per cent comes from the Bulbourethral and urethral.
