Pigs make better men
» Medical
Oladapo Ashiru, researcher in reproductive endocrinology, says the human male just cannot compare to the pig.
Take the pig to really show superior animal fertility! The pig ejaculates an entire pint of sperm on having sex with the sow. Its orgasm will take a full half hour. Compare this to a mere 120 seconds for most men. In addition the pig has little screw-like grooves on the end of its penis that fits into a similar groove in the cervix of the female. This guaranties that sperm will not leak during intercourse. The amount of sperm in a pigs ejaculate is about four hundred times higher than the amount sperm in a single human ejaculate and none is lost.
Human reproduction is very inefficient, says Ashiru, fertility expert
