- The  semen is fluid produced in the seminal vesicles and prostrate. On  ejaculation the sperm travels from the testes, through the  ejaculatory ducts, and mixes with the seminal fluids to be expelled  through the penis. The fluids are replenished each time they are  ejaculated.

- By Dr. Ananya Mandal, MD. Semen is a greyish white bodily fluid that is secreted by the gonads of male animals. It carries sperm or the spermatozoa and fructose and other enzymes that help the sperm to survive to facilitate successful fertilization.The whitish opalescence is due to the large amount of protein that it contains and its slightly turbid appearance is due to the spermatozoa contained within it.he white color of the semen is due to secretion from the prostate glands containing enzymes, citric acid, lipids, and acid phosphatase. This forms around 25-30% of the semen base. At each ejaculation around 200-500 million sperms are released by the testes. This forms about 2-5% of the semen composition.

Semen Semen is made up of sperm (male cells for sexual reproduction) floating in a fluid called seminal plasma. Sperm, also called spermatozoa, are made by a man's testicles and mature (grow up) in the epididymis. The fluids in seminal plasma come from different glands in the man's body: the seminal vesicles, prostate and bulbourethral glands (also called the Cowper's glands).

Human Reproductive Anatomy and Gametogenesis Sperm develop in the seminiferous tubules that are coiled inside the testes . The walls of the seminiferous tubules are composed of the developing sperm cells, with the least-developed sperm at the periphery of the tubule and the fully-developed sperm in the lumen. The sperm cells are mixed with nursemaid cells called Sertoli cells which protect the germ cells and promote their development.

Sperm Oomycetes form sperm nuclei in a syncytical antheridium surrounding the egg cells. The sperm nuclei reach the eggs through fertilization tubes, similar to the pollen tube mechanism in plants.perm cells are carried out of the male body in a fluid known as semen. Human sperm cells can survive within the female reproductive tract for more than 5 days post coitus. Semen is produced in the seminal vesicles, prostate gland and urethral glands.

Seminal vesicle Each vesicle forms as an outpocketing of the wall of the ampulla of one vas deferens. The seminal vesicles develop as one of three structures of the male reproductive system that develops at the junction between the urethra and vas deferens.bout 70-85% of the seminal fluid in humans originates from the seminal vesicles, but is not expelled in the first ejaculate fractions which are dominated by spermatozoa and zinc-rich prostatic fluid.

- Semen is the fluid which is ejaculated at the end of the sexual act of a male. The primary components in semen are sperm cells, prostaglandins, citric acid, enzymes, amino acids, flavins, proteins, Vitamin C, phosphorylcholine, zinc, prostrate specific antigen, acid phosphatase, mucus and sialic acid. Semen acts as a medium to carry the sperm to the female genital tract.

Reproductive structures of angiosperm? Best Answer: There are two reproductive structures in angiosperm, namely the stamen or the androecium, the male part which produce the pollen and the female part which is called gynoecium or the pistil. The stamens consists of anther which housed the pollen grain, connected by filament, a tube-like structure which connected the anther to the flower structure.

- After the seminal vesicles, the next accessory gland to contribute to the semen production is the prostate gland. The prostate produces prostatic fluid. This acidic fluid makes up about 20-30% of the semen. It also contains proteins with antibiotic properties that help prevent infections in the male reproductive tract.

- Seminal gland. The seminal gland, more commonly referred to as the seminal vesicle, holds the liquid that mixes with sperm to form semen. Semen combines fluid elements from the epididymis, seminal vesicles, prostate gland, and vas deferens.Each body part plays a key role in semen production.his gland is located behind the bladder, above the prostate gland, and in front of the rectum. It is about two inches long, on average. This gland releases a fluid rich in sugars (especially fructose), which feeds the sperm.

Semen Semen is produced and originates from the seminal vesicle, which is located in the pelvis.epending on the species, spermatozoa can fertilize ova externally or internally. In external fertilization, the spermatozoa fertilize the ova directly, outside of the female's sexual organs. Female fish, for example, spawn ova into their aquatic environment, where they are fertilized by the semen of the male fish.

Human Reproductive Anatomy and Gametogenesis Diagram the structures of human male reproductive anatomy. The male gonads, or testes, produce sperm within the seminiferous tubules; the sperm are housed here until they are nearly mature, at which point they enter the epidydimis for full maturation.

Semen Semen, also known as seminal fluid, is an organic fluid that may contain spermatozoa. It is secreted by the gonads and other sexual organs of male or hermaphroditic animals and can fertilize female ova. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or swim. Semen is produced and originates from th

Semen Semen is mostly water, but it also contains amino acids and protein, sugars, minerals, and in fertile men sperm cells! 1. The combination of fluids that comprise the seminal fluid are produced by a series of male sex glands: namely the prostate, seminal vesicle, and bulbourethral (Cowper’s) glands.emen (meaning seed in Latin), male ejaculate, or “cum, is a combination of seminal fluid and mature sperm (spermatozoa), which is ejaculated through the urethra during the male orgasm. Semen is the medium through which a male’s sperm is delivered to a female’s egg cell, or ovum, during procreative sex.

Spermatogenesis Spermatogenesis, the origin and development of the sperm cells within the male reproductive organs, the testes. The testes are composed of numerous thin, tightly coiled tubules known as the seminiferous tubules; the sperm cells are produced within the walls of the tubules.

Testicular/Scrotal Disorders Hydrocele is a term used to describe a dilated sac of fluid which forms around the testicle. The male anatomy is shown in the picture. The scrotum, or sac, contains a testicle on each side. The testicle has two functions. It makes testosterone, the male hormone, which is absorbed into the blood stream.

Semen It contains spermatozoa and fructose and other enzymes that help the sperm to survive and facilitate successful fertilization. During the process of ejaculation, the semen is ejaculated from the seminal vesicle in the pelvis, which is where it is produced.

Semen During the process of ejaculation, sperm passes through the ejaculatory ducts and mixes with fluids from the seminal vesicles, the prostate, and the bulbourethral glands to form the semen. The seminal vesicles produce a yellowish viscous fluid rich in fructose and other substances that makes up about 70% of human semen.emen is typically translucent with white, grey or even yellowish tint. Blood in the semen can cause a pink or reddish colour, known as hematospermia, and may indicate a medical problem which should be evaluated by a doctor if the symptom persists.

- Semen is the fluid that a man ejaculates. This fluid is produced at several different sites. The sperm within the semen are the cells that actually fertilize the egg and are therefore the most important to assess. However, the sperm account for only 1% to 2% of the semen volume.

Anatomy of the Testes The epididymis, vas deferens and seminal vesicles (male duct which transport sperm to the penis) have formed at this stage. They do not form part of the structure of the testes, but they descend with the testes into the scrotum. These ducts collectively form the spermatic cord which transports sperm to the penis.

- Anyone who said semen is stored in the balls or testes (testicles) is wrong. The testes create sperm, a portion of the semen but that is all. The mature semen is stored in the ductus deferens, a muscular tube that carries sperm superiorly from the epididymis into the abdominal cavity to the ejaculatory duct.
