what primary function do the male’s vas deferens serve
Vas deferens The vas deferens (Latin: "carrying-away vessel"; plural: vasa deferentia), also called ductus deferens (Latin: "carrying-away duct"; plural: ductus deferentes), is part of the male reproductive system of many vertebrates; these vasa transport sperm from the epididymis to the ejaculatory ducts in anticipation of ejaculation. It is a partially coiled tube which ascends into the abdomen through the inguinal canal.
Urethra Females use their urethra only for urinating, but males use their urethra for both urination and ejaculation.[1] The external urethral sphincter is a striated muscle that allows voluntary control over urination.[2] Only in the male is there an additional internal urethral sphincter muscle.[3]
