$\blue {\bf{Here \: is \: the \: answer !! }}$

♦Seminal Vesicles and Prostate glands are accessory glands of male reproductive system.

$\bf{Seminal \: Vesicles : }$
✴ The Seminal Vesicles are a pair of simple tubular glands present postero-inferior to the urinary bladder in the pelvis.

✴ Each Seminal Vesicle opens into the corresponding vas deferens , where the vas deferens enters the prostate gland.

✴The secretion of Seminal Vesicles constitute about 60% of the seminal fluid.

✴It is an alkaline viscous fluid that contains fructose, proteins , citric acid , inorganic phosphorus, potassium and prostaglandins.

✴Once this fluid joins the sperm in the ejaculatory duct, fructose acts as the main energy source for the sperm outside the body.

✴ Prostaglandins are believed aid Fertilization by causing the mucous lining of the cervix to be more receptive to sperm as well as aiding the movement of the sperm towards the ovum with peristaltic contractions of the uterus and the fallopian tube after coitus.

$\bf{Prostate \: Gland : }$

✴ Prostate gland is located directly beneath the urinary bladder.

✴The gland surrounds the prostatic urethra,and sends it's secretions through several prostatic ducts.

✴In man, the prostate contributes 15-30 % of the semen .

✴The fluid from the prostate is clear and slightly acidic.

✴ The prostate secretion activates the spermatozoa and provides nutrition.

Answer 2

Both of the organs are belonging to the complex part of Male reproductive system which are made up of mainly the testicular organ (also called primary sexual organs), the bag pouch structure scrotum, Vasa efferentia or also called as ductulus or ductuli efferentes, Epididymes, Vasa deferentia or vas deferens, seminal vesicles, ejaculatory ductile structures, Urethra, prostate gland, Bulbourethral or Cowper's gland and lastly the muscular organ used in copulation.

Seminal Vesicles are in pairs and gland consisting of loveless in contortions made up of briefly upon muscular and glandular structures or "Musculoglandular sac structures"  that are of 5 centimeters in length when they're coiled into a stiff rounded corner and when un-coiled they extend upto 10 centimeters to 15 centimeters in between the rectal organ and the urinary bladder. Every pair has a tubal opening that is in a conjointly formed pipe or forming a passage from vas deferentia or vas deferens to create a duct for ejaculation. Seminal Vesicles are into secretions of the major fluid supporting sperm called as Semen in about 60 to 70%. Characteristics of Semen formed by Seminal Vesicles are often described as thick as paste, immensely viscous, containing mucoid or mucous like texture, also alkaline in chemical nature which conclude the following proteins for specific functionaries which support reproduction like, fibrinogen for maintenance of textural properties, fructose as to nourishing, nursing and nurturing the activities done by sperm for travelling, citrate or citric acids maintains basic norms of neutralised factors, inositol and prostaglandins are for liquefaction of mucous present in the cervical region and to stimulate certain movements in the female tracts including uterine wall and urinary bladder.

Prostate gland is colored in a grayish to inclining in reddish kind of gland which is having the width of 4 centimeters and height of 3 centimeters if we were to say it'd be approximately a size of a typical golf ball. It's enclosed into the important part of urethral gland which contain a junctionary path which are fixed with ducts for ejaculation. This gland encloses upto 30 to 40 glandular tubules which are divided into alveolar structures or "tubuloalveolar formations" which furthermore extend in a different path into urethra with fine parted ducts containing them. Prostate gland include glandular secretions which are thin in viscosity and diluted, milky in nature of basic pH making them alkaline in their bases that too in small quantities. Prostate glands secretions compose of citrate, an important enzyme aiding in clotting factors, profibrolysin, calcium and phosphate chemical groups. A total of 30 to 40 percentage of semen is constituted into the Prostate secretions. It's vitality is a must for ensuring essentially derived motility of sperms for energy consumption and reaching of destination, removal or cutting of tubes in Prostate glands will permanently make the male human sterile and wouldn't be able to produce fertile sperms.
