Soybean Cyst Nematode's have both a female and male gender. They are born with one or two gonads . In the males , the sperm is produced at the end of the gonads. It then travels along the the length of the nematodes body until it reaches the testes. the testes open into a relatively wide sperm duct and then into an ejaculatory duct.Reproduction is always sexual. During reproduction the male grabs the female and inserts his ejaculatory spicules into the female and the sperm crawls into the females genital pores.
