function of ejaculatory duct in male reproductive system
Ejaculatory duct Sperm is produced in the testes and enters the ejaculatory ducts via the vas deferens. As it passes by the seminal vesicles, a fluid rich in fructose combines with sperm. This addition nourishes the sperm in order to keep it active and motile.[6] Seminal fluid continues down the ejaculatory duct into the prostate gland, where an alkaline prostatic fluid is added.[4] This addition provides the texture and odor associated with semen.[4] The alkalinity of the prostatic fluid serves to neutralize the acidity of the female vaginal tract in order to prolong the survival of sperm in this harsh environment.[6] Semen is now a fructose-rich, alkaline fluid containing sperm as it enters the bulbourethral glands below the prostate.[6] The bulbourethral glands secrete a small amount of clear fluid into the urethra before the ejaculate is expelled. The functions of this fluid are not entirely known but are suggested to aid in lubricating the male urethra in preparation for the semen during ejaculation.[4] The amount of semen produced and expelled during ejaculation corresponds to the length of time that the male is sexually aroused before ejaculation occurs.[4] Generally, the longer the period of arousal, the larger the amount of seminal fluid.[7]
Seed Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the seed coat from the integuments of the ovule.

Ejaculatory duct The ejaculatory ducts (ductus ejaculatorii) are paired structures in male anatomy.[1] Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle.[2] They pass through the prostate, and open into the urethra at the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus.[3]
