Question

Give a short note on female reproductive system of leech.

Answer 1

Female Reproductive System:

• It consists of ovaries, oviducts and vagina. There is a single pair of ovary in the 11th segment on the ventral side.
• Each ovary is a coiled ribbon-shaped structure. The ova are budded off from the ovary.
• From each ovary runs a short oviduct. The oviducts of the two sides joins together, to form a common oviduct.
• The common oviduct opens into a pear-shaped vagina which lies mid-ventrally in the posterior part of the 11th segment.
