Shemale semen and male semen

[russellwu]

The testicles shrink too, I think. That's probably why when the tgirl is lying on her back, the scrotum looks empty, because the testicles can "fall" into a sort of cavity inside the pubic bone.
(The testicles actually start from there, somewhere in front of the bladder, surrounded by the pubic bone. As the infant matures, the testicles descend into the scrotal sacs)

Russell Crowe,
Thank you, for the anatomy lesson.

Semen consists of:

sperm cells (from the testes)=5% of semen
+
Secretion from the Seminal vesicles = 30% of Semen;
(thick, Alkaline Liquid contains nutrients, amino acids, citric acid, fructose to boost the sperm cells)
+
Prostate gland fluid= 60% of semen
(thin, Alkaline, milky liquid)
+
Cowper's gland fluid= 5% of semen
(Precum= alkaline lubricant)

You must be wondering, why most of the liquids are alkaline?

Well, most fluids constituting the semen are alkaline to neutralise or counter the acidity of the urethra or the vagina. Alkaline environment is helpful for sperm survival and mobility. Acidic medium kills the sperm cells.

How long does a sperm take to grow up?

A sperm cell {from it's immature form inside the seminiferous tubules (testes) to the mature stage in the Vas Deferens, where it cues up for ejaculation} takes 2.5 months or 74 days to mature.
So, its costly stuff, man!
