The document compares and contrasts the male and female genital organs. It describes the key structures of the male organs including the scrotum, testes, epididymis, vas deferens, seminal vesicles and prostate. It discusses sperm production and the components and mechanism of semen emission and ejaculation. The document also covers age-related changes to the male organs and some common issues like varicocele, vasectomy, benign prostatic hyperplasia and erectile dysfunction.

3. Compare and contrast the general organizations of the male and female genital
organs
Structure Function in the Female Function in the Male
Hormone Estrogen Testosteron
Primary Sex Organ Ovaries :
 Produces estrogen
 Houses Graafian follicles
 Egg, ovum are released from the ovary
Testes:
 Produces Testosteron
 Houses seminiferous tubules
 Epididymis
 Sperm leave the seminiferous tubules
What is an ectopic Pregnancy Fimbriae “capture” released egg Sperm enter the epididymis
Where does fertilization of an egg normally
occur?
Unfertilized egg travels through the fallopian
tube
The sperm leave the epididymis and enter the
vas deferens
What is the term that means surgical removal
of the uterus?
Unfertilized egg enters the uterus :
 Fundus
 Body
 Cervix
 Vagina
The sperm leave the vas deferens and enter the
urethra to exit the urinary meatus.

4. Identify and describe the location, gross anatomy, and functions of the principal structures of the male genital
organs
• Scrotum
• Testis
• Epididimis
• Vas Deferens
• Ductus ejakulatori
• Vesikula seminalis
• Prostat
• Kelenjear Bulbourethral
• Penis

6. histological features of gonads, ducts, and accessory glands of the male genital organs.
• Testis

7. Epididimis

8. Prostat

9. Vesikula Seminalis

10. Spermatogenesis

11. Components of semen
• Semen, also called seminal fluid, is emitted from
the male reproductive tract that consists of two
components, seminal plasma and sperm
• After emerging from the testes, sperm are stored
in the epididymis, in which secretions of
potassium, sodium, and glyceryl
phosphorylcholine (an energy source for sperm).
• During the process of ejaculation, liquids from
the prostate gland and seminal vesicles are
added, which help dilute the concentration of
sperm and provide a suitable environment for
them.
• Fluids contributed by the seminal vesicles contain
fructose, amino acids, citric acid, phosphorus,
potassium, and hormones known as
prostaglandins.

12. Mechanism of Erection, Emission and
Ejaculation
• When the blood vessels of the corpora cavernosa relax and open up,
blood rushes in through the cavernosus arteries to fill them.
• The blood then gets trapped under high pressure, creating an
erection.
• The blood creates pressure in the corpora cavernosa, making the
penis expand and creating an erection.
• Emission is the expulsion of the seminal fluid released by supportive
reproductive organs (prostate, seminal vesicle) through ejaculate
ducts (efferent vessels of the testicle, epididymis, and vas deferens)
and deposited in the prostatic urethra due to the reflex contraction of
such organs.

13. • Contractions are the driving force of the ejaculatory reflex, applying
pressure on the base of the penis expulsing the semen in three to
seven spouts.
• The internal sphincter of the urinary bladder neck remains closed so
that the seminal fluid can make it to the penis

14. Age-related changes in the male genital organs
• Mean testicular volume tends to increase between 11 and 30 years of
age, remains constant between 30 and 60 years of age, and decreases
gradually every year after age 60. The mean testicular volume in men
over 75 years has been reported to be 31 % less than in men between
18 and 40 years of age.
• This difference is associated with significantly higher mean serum
levels of gonadotropins and lower serum free testosterone (T).
• Prostate enlargement in older men is one of the most common age-
related diseases and is defined as benign prostatic hyperplasia (BPH).

15. • Varicocele : an enlargement of the veins within the loose bag of skin that holds the testicles (scrotum).
The symptoms is pain, mass in the scrotum, differently size testicles, infertility.
• Vasectomy : Vasectomy is a form of male birth control that cuts the supply of sperm to your semen. It's
done by cutting and sealing the tubes that carry sperm. Vasectomy has a low risk of problems and can
usually be performed in an outpatient setting under local anesthesia.
There are 2 types of vasectomy: conventional vasectomy using a scalpel and no scalpel vasectomy
• Benign prostatic hyperplasia (BPH) is a health issue that becomes more common with age. It's also
called an enlarged prostate.
• Erection Dysfunction Psychosomatic
• Erection Dysfunction Structural / Organic
