Seijiro is my best friend.

The male reproductive organs include the vas deferens.

He is doing semen drinking every day.

This product contains dextrin.

This gum contains saccharin.

I take ginseng extract every day.

He went to a clinic for semen collection.

He works collecting semen from cows.

The room was filled with a dim light.

The character '囶' can sometimes mean 'country'.
