PENIS
ERECTILE TISSSUE (VASCULAR)ERECTION RESULTS FROM GORGING
TISSUE WITH BLOODERECTION IS A PARASYMPATHETIC
SPINAL REFLEX TO TACTILE AND OTHER STIMULATION ENHANCED BY SYMPATHETIC INHIBITION

SEMINAL VESSICLES, PROSTATE GLAND, BULBOURETHRAL GLANDS
PROVIDE THE BULK OF THE SEMEN, A MIXTURE OF SECRETIONS, SPERM AND MUCOUS
FRUCTOSE AND PROSTAGLANDINS FROM SEMINAL VESSICLES
ALKALINITY AND CLOTTING ENZYMES FROM PROSTATE
LUBRICANT FOR INTERCOURSE FROM BULBOURETHRAL GLANDS

EPIDIDYMUS, VAS DEFERENS, URETHRA: EJACULATION
ROUTE OF EXIT OF SPERM DUCTUS DEFERNS STORES SPERM DURING EMMISSION PHASE OF EJACULATION
SPERM ARE EMPTIED INTO URETHRA BY SYMPATHETICALLY INDUCED CONTRACTIONS
MOTOR NEURON INDUCED CONTRACTIONS OF SKELETAL MUSCLES AT BASE OF PENIS EXPELL THE SEMEN DURING EXPULSION PHASE OF EJACULATION
EJACULATION IS A PART OF ORGASM
