In order to become pregnant a male must ejaculate (release seminal fluids containing sperm) inside the female's vagina once the female has reached her reproductive stages (usually around 11-14) and the sperm must fertilize the egg.

The gestation stage is when the embryos develop inside the female platy's body. Finally, the birth stage is when the female platy gives birth to live young. Unfortunately, I am unable to provide pictures to illustrate these stages.
