how to do a testicular self - exam

1. exam each month. after a warm shower, when the scrotum is relaxed.

(7) penis (5) prostate gland
(6) urethra (2) epididymis
(1) testis

Explanation:

This content is about the male reproductive system, which falls under Biology (a subfield of Natural Science). Let's fill in the blanks:

1. Nutrient fluid from the seminal vesicle (provides energy for sperm travel).
2. Fluid from the prostate gland (prolongs sperm lifespan).
3. Lubricating and neutralizing fluid from the Cowper's gland (bulbourethral gland) (helps sperm glide out of urethra).
4. Ejaculation - process by which semen leaves the man’s body.
5. Between 20 million and 100 million sperm may be released in an ejaculation (typical range).
6. The primary sex hormone in males is testosterone.
7. Erectile dysfunction (ED) - the inability to maintain an erection.
8. Nocturnal emission - spontaneous ejaculations during sleep ("wet dreams").
9. Circumcision - surgical removal of the foreskin from the penis.
10. Smegma - a white/yellow substance under the foreskin (dead skin, oils, moisture).

Answer:

• Nutrient fluid from the \boxed{seminal vesicle} (Energy for the sperm’s travel)
