“In humans, it is thought that the sperm that are first to reach the fallopian tubes – down which the eggs travel – are the best ones, says Sakkas. IVF clinics typically select the strongest swimmers and use them to fertilise eggs within hours.”
Truly Bear is conning you girls but just remember he has older sperm.
Are you laughing?
