Let us be clear: there are only two genders. And no, I don’t mean sexes, although there are only two genders because there are only two sexes. All the rest are fake genders.
Let me explain. Sex is a reproductive system with two morphs, one we call female and the other male. The former produces large, immotile gametes called ova which — and this is important — the female retains inside her body, in mammals.
The latter, the male, produces small, highly motile gametes called spermatozoa or sperm, which are able to swim.
For reproduction to occur, the male must get his sperm into contact with the ovum, which is deep inside the female’s body. In order to enable this, males have an organ called a penis, which is generally long and thin, which can deposit sperm, contained in a fluid called semen, near to the ovum.
