Male Reproductive Health System

The male reproductive health system organs are written below:
1. Scrotum
2. Testis.
3. Vas deferens (deferent duct)
4. Penis
5. Accessory x Organs.

(a) Seminal Vesicle.
(b) Prostate.
(c) Bulbourethral Glands (Cowper’s gland)


Male reproductive organs are mostly male external genital organs that lie external to body in between thighs in Midline.

Scrotum is a hanging skin sac in between the thighs.

Testis are a pair of sex glands. The two testes are suspended in the scrotum by spermatic cord.
Each testis is whitish ovoid solid gland. It measures 5cm long, 2.5 cm broad and 3 cm antero posteriorly.

Structure of Testis

From Inward
(a) It has thick fibrous capsule-tunica albuginea fibrous septa divides the testis into 250 lobules.
(b) In each lobule lies one-three coiled seminiferous tubles.
(c) On the posterior surface of testes efferent ductules drains the rest testes into long coiled duct- epididymis.

Each Seminiferous tubule Contains
(a) Basement membrane.
(b) Spermatogonia cells- During puberty to old age these cells with 46 diploid chromosome divide the primary spermatocyte (46 chromosome) by mitosis, then to smaller secondary spermatocyte (23 haploid chromosome) by meiosis divide to smallest spermatids (23 haploid chromosome) by second meiosis being embedded on free end of sertoli cells.
Spermatozoa cells with tail are formed and released within lumen of seminiferous tubules from spermatids.
(c) Sertoli cells- these are large polygonal cells extending from base to tubular Lumen.
(d) Interstitial cells (leyding cells) these cells produce Testosterone.


Vas deferens on each side is a muscular excretory duct of testes.
It is hollow tube 45cm long and 3mm in diameter. Imm Lumen. Each duct starts at tail of epididymis. Courses up at back of spermatic cord in scrotum enters pelvic cavity through anal canal and ends at dilated ampullary part. The latter join duct of seminal vesicle on posterior surface of urinary bladder to form ejaculatory duct. Ejaculatory duct opens into prostatic urethra which runs into urethral passage.


Vas deferens has outer connective tissue layer, Middle muscle layer and inner mucous layer with single layer of columnar epithelia.It weighs 10.5-14 gm.


Penis is 10 cm long, 4 cm broad flaccid muscular cylindrical organ that lies at the base of scrotum in front on midline.

The rounded bulb end of penis is called glans.
Glans is covered with foreskin. It is male external genital organ for passage of urine through penile urethra and ejaculation of semen to exterior during copulation when it gets erected to 6″ or more.


The accessory Reproduction Organs are :

(a) Seminal Vesicle: It is paired 5cm long coiled accessory sex gland lying on either side of ampulla of vas deferens.
(b) Prostate : Is a midline fibromusculo glandular sex gland that lies between neck of urinary bladder. It is transversed by prostatic urethra and two ejaculatory ducts.

(c) Bulbourethral glands (Cowper’s glands): Two round glands lie one on either side of the deep perineal touch their ducts open into penile urethra.

Female Reproductive System, Cell, System Diagram

Reproductive Organs in female are those which are concerned with copulation (Coitus), fertilization (The impregnation of the female sex cell, the ovum, by a male sex cell, a spermatozoon), growth and development of fetus and its exit to the Outer World .

Classification of female reproductive organs
The female reproductive organs are broadly divided into
(a) External Genitalia (Vulva or Pudendum)
(b) Internal Genitalia
(c) Accessory reproductive organs.


Vulva Includes
(a) Mons Veneris
(b) Labia Majora (Greater Lips)
(c) Labia Minora (Lesser Lips)
(d) Clitoris
(e) Vestibule
(f) Perineum

These all are visible on external examination.

Anteriorly – Mons Veneris

Laterally – Labia Majora
Posteriorly – Perineum


Mons pubis is a pad of subcutaneous adipose connective tissue lying in front of pubis or over the symphysis pubis.

In adult female the Mons Pubis is covered by hairs.


The Vulva is bounded on each side by the elevation of skin and subcutaneous tissue which form the labia majora. They are continuous but medially they form the posterior commissure in front of the anus. The inner surface of Labia Majora are Hairless Labia Majora is composed of skin, fibrous tissue, fat, sebaceous glands, sweat glands. Beneath the skin are dense connective tissue and adipose tissue. The adipose tissue is richly supplied with venous plexus which may produce haematoma if injured during childbirth. Labia majora is same as scrotum in male.


These are 2 smaller folds of skin between the labia majora containing numerous sebaceous glands.

Anteriorly they divide to enclose the clitoris and unite with each other in front and behind the clitoris to form the prepuce and frenulum.

The lower portion of labia minora fuses across the midline to form a fold of skin known as fourchette. It is usually lacerated during childbirth.

Between the fourchette and the vaginal orifice is the fossa navicularis. Labia Minora do not contain hair follicles. The folds contain connective tissue, numerous sebaceous glands, erectile muscle fibres and numerous vessels and nerve endings.


Clitoris corresponds to penis in male. It is small cylindrical erectile body measuring 2.5cm situated in the most anterior part of the vulva. Clitoris is extremely sensitive and highly vascular and plays a part in the orgasm of sexual intercourse. It is attached to the under surface of the symphysis pubis by the suspensory ligament.

Parts of Clitoris: It consists of:

(a) A glans (Covered by squamous epithelium & richly supplied with nerves)

(b) A body and
(c) Two Crura


It is a triangular space bounded anteriorly by the clitoris. Posteriorly by the fourchette Laterally (either side) by Labia Minora. There are 4 openings into the vestibule
(a) Urethral Opening.
(b) Vaginal Orifice & Hymen.
(c) Openings of Bartholin’s ducts (2 in number)

(a) Urethral Opening

It is situated in the midline just in front of vaginal orifice about 1-1.5cm below the pubic arch. It consists of paraurethral ducts.

These ducts either open into posterior wall of urethral orifice or directly into the vestibule.

(b) Vaginal Orifice and Hymen
(i) Vaginal Orifice: The Vaginal Orifice lies in the posterior end of the vestibule and is of varying size and shape. In Virgins and nullipara the opening is closed by the Labia Minora, but in parous it may be exposed.

(ii) Hymen: The Vaginal Orifice is incompletely closed by a septum of mucous membrane called Hymen-The membranes vary in shape but is usually circular or crescentic in Virgins. It is usually ruptured at Consummation of Marriage. T During childbirth it is extremely lacerated and U is later represented by Cicatrised Nodules of varying size called the carunculae Myrtiformes on both sides. It is lined by stratified squamous epithelium. in de

(c) Opening of Bartholin’s Duct
Greater Vestibular or gland-There are 2 Bartholin glands one on each side.
(i) Size: Pea Sized
(ii) Colour: Bartholin’s ducts are yellowish white vul in colour.
(iii) Location: They are situated in the superficial perineal pouch close to the posterior end of vestibular bulb.
(iv) Function: During sexual excitement it secretes child abundant alkaline mucus which helps in lubrication.
(v) Lining of Bartholin Duct: The duct is lined by columnar epithelium but near its opening by stratified squamous epithelium.
(vi) Vestibular Bulb: These are bilateral elongated masses of erectile tissue situated beneath the mucous membrane of the vestibule.
They are homologous to the single bulb of the penis and corpus sponglosum in the male. They are likely to be injured during childbirth with brisk haemorrhage.

Perineum is the area extending from the fourchette to the anal canal. It is roughly triangular and consists of connective tissue, muscle and fat. Boundaries of Perineum.
(a) Perineum is bounded above by the inferior surface of the pelvic floor.
(b) Below by the skin between the buttocks and thighs.
(c) Laterally it is bounded by ischiopubic rami, Ischial tuberosities and sacrotuberous ligament.
(d) Posteriorly it is bounded by Coccyx

(c) Cervix

(i) It is cylindrical in shape and measures about 2.5cm.

(ii) It extends from the isthmus and ends at the external OS which opens into the vagina after perforating its anterior wall.

(iii) The part lying above vagina is called supravaginal and that which lies within the vagina is called vaginal part.


The cavity of uterine body is triangular on coronal section with the base above and apex below.
(a) It measures 3.5 cm. There is no cavity in fundus.
(b) The cervical canal is fusiform and measures about 2.5cm.

Q.17. What is the function of testes?

Ans. The testes are the male gonads and produce ies spermatozoa and the hormones testosterone. Testerone eds responsible for the secondary sex characteristics together with follicle stimulating hormones (FSH), it also promotes production of sperm.

Q.18. Describe the function of spermatic cord and seminal Vesicles?

Ans. Function of Spermatic cord – Spermatic cord is transmits the deferent ducts up into the body, along with other structure. The function of deferent duct is to carry the sperm to the ejaculatory duct.

Q.22. What is the function of penis?

Ans. It continues with the urethra, which is a passage for both urine and semen. It stiffens (develops an erection) during sexual stimulation in order to enter the vagina and release the semen close to the woman’s cervix.

Q.23. What is the process of formation of spermatozoa?

Ans. Sperm production starts during puberty and lasts until adulthood. Spermatogenesis takes place in the semini ferous tubules under the influence of FSH and testosterone. Maturation is a drawn-out process that takes a few weeks. Until ejaculation, the mature sperms are kept in the deferent duct and epididymis. In the absence of this, they deteriorate and become reabsorbed. 2-4 ml of semen are deposited in the vagina with each ejaculation. Every millilitre of seminal fluid contains roughly 100 million sperms. only 20–25% of which are likely to be abnormal. The remaining ones travel between 2-3 mm per minute. Each spermatozoan is made up of a head, a body, and a long, movable tail that laces to move the sperm forward. An acrosome, which covers the tip of the head, contains enzymes that can penetrate the ovum’s coating by dissolving it.

Q.24. Define Fornices.

Ans. The fornices are the clefts formed at the top of vagina (Vault) due to projection of the uterine cavity through the anterior-vaginal wall where it is blended inseparably with its wall.

Q.25. With which organ in male is the labia majora homologous.

Ans. Labia majora is homologous with scrotum in male.

Q.26. Define fourchette?

Ans. The lower portion of the labia minora fuses across the midline to form a fold of skin known as fourchette” It is usually Lacerated during Childbirth.
