1. Determining the Gender of the Fetal Pig

2. Gender of the Fetal Pig
Although the animals are unborn, differences between the sexes are readily seen.
The older the specimen the more pronounced these external differences will be.

3. FEMALE Fetal Pig The female is identified by the urogenital papilla.
Urogenital papilla is a small fleshy conical projection ventral to the anus.
The anus is ventral to the tail and is clearly seen in both males and females, when the tail if lifted.

4. FEMALE Fetal Pig
Locate the female’s external genital opening at the base of the urogenital papilla.
Urogenital = external opening for both the urinary wastes and the reproductive or genital system.

5. MALE Fetal Pig
The urogenital opening in males is located on the mid-ventral surface, posterior to the umbilical cord.
It is the opening of the penis.
The penis is internal, under the skin, between the urogenital opening and the scrotum.

6. MALE Fetal Pig
The male testes lie in the scrotum, a double pouch structure ventral to the tail.

7. Determine the Gender of Your Pig
Using the previous descriptions of the differences between female and male fetal pigs, determine the gender of your ping.

8. FEMALE and MALE Fetal Pigs
Both males and females possess mammary papillae.
In mature females these become the nipples by which the young receive the milk from the mammary glands.
How many pairs of mammary papillae do you count in your specimen?
