REPRODUCTIVE SYSTEM 01

Identify the genital ridge (5) in this 51/2 week embryo at the indifferent stage of gonadal development.

REPRODUCTIVE SYSTEM 02

This is the abdominal region from a 9 week old female fetus. Identify and describe the development of the following structures: bladder (2), genital tubercle (distal to #3), metanephros (4), suprarenal gland (9), ovary (6), rectum (7), round ligament of the uterus

(8), suspensory ligament of ovary (10), uterine tube (12), uterovaginal primordium (13).

REPRODUCTIVE SYSTEM 03

Enlarged view of 9 week female pelvis showing rectum (7), ovary with primordial follicles (6), round ligament of

uterus (8), uterine tube (12) and uterovaginal primordium (13).

REPRODUCTIVE SYSTEM 04

Identify and describe the development of the external genitalia in a 9 week female fetus: clitoris (3), labia majora (4), labia minora (5).

REPRODUCTIVE SYSTEM 05

Identify and describe the development of the external genitalia in a 9 week old male fetus: anus (1), labioscrotal

swelling (3), urethral folds, urethral groove (7), phallus (5).

REPRODUCTIVE SYSTEM 06

IDENTIFY the following in a ten week male fetus: labioscrotal swellings (2), genital folds (8), urethral groove (7),

glans penis (4), scrotal raphe (5), scrotum (6).

REPRODUCTIVE SYSTEM 07

This dissection of a 13 week male shows the body of the penis (6), the urethral meatus (12), the scrotal raphe (8), and the scrotum (9).

REPRODUCTIVE SYSTEM 08

Identify the following internal male organs: testes (7), bladder (2), rectum (5), ductus deferens.

REPRODUCTIVE SYSTEM 09

Explain embryological basis of hematocolpos

REPRODUCTIVE SYSTEM 10

Explain embryological basis for double uterus. Why is one side enlarged?

REPRODUCTIVE SYSTEM 11

Explain the embryological basis for double cervix.

REPRODUCTIVE SYSTEM 12

Explain the embryological basis for double vagina.

REPRODUCTIVE SYSTEM 13

What is a possible explanation for this condition known as micropenis?

REPRODUCTIVE SYSTEM 14

Recognize and describe the most likely cause of cryptorchidism.

REPRODUCTIVE SYSTEM 15

Identify a unilateral indirect hernia.

REPRODUCTIVE SYSTEM 16

Recognize and describe the embryological basis for hypospadias.

REPRODUCTIVE SYSTEM 17

This four year old genetic male is an example of 21-hydroxylase deficiency. Explain the hormonal basis for this

abnormality. (Review hormonal products of suprarenal gland and estrogen precursor dihydroepiandrosterone).

REPRODUCTIVE SYSTEM 18

Contrast the result of 21-hydroxylase deficiency in a genetic female with the same condition in the male.

REPRODUCTIVE SYSTEM 19

This is an example of ANDROGEN INSENSITIVITY SYNDROME. This individual is a genetic male with an absence of testosterone receptors on the normally responsive tissue. The abdominal scar is from bilateral

orchidectomy.

REPRODUCTIVE SYSTEM 20

This is the external genitalia of a male with testicular feminization. Note the oversized clitoris, labia majora fused

posteriorly and rudimentary vagina. The labia minora can also be identified.
