Science Genius - Reproduction Rap (Teaser Bars) lyrics

[Verse 1 - Ryan Rivera] When a man and woman make love in a bed or sofa And then the s**m have a journey just to try to reach the ova Then when it enters the cervix, the s**m start running That's when the function starts: that's s**ual reproduction Now the function the male produces is testosterone Which is a hormone like females produce estrogene and progesterone And when the s**m finally reaches the ova and the journey's over It becomes a zygote and waits 'till it's nine months older
