What is the male reproductive organ in female?
Most people think of the gonads as the male testicles. But both sexes have gonads: In females the gonads are the ovaries, which make female gametes (eggs). The male gonads make male gametes (sperm). When a baby girl is born, her ovaries contain hundreds of thousands of eggs, which remain inactive until puberty begins.
What are the 8 male reproductive organs?
The male reproductive system includes the penis, scrotum, testes, epididymis, vas deferens, prostate, and seminal vesicles. The penis and the urethra are part of the urinary.
What are the males organs?
The external organs include the testes, the penis, the scrotum and epididymis. The internal organs include the spermatic cord, the prostate, the bulbourethral gland, and the seminal vesicles.
What is sperm Class 8?
A sperm is single cell with all the usual cell components like nucleus, cytoplasm and cell membrane. The nucleus of sperm cell is tightly packed in its head. The sperm cells has very little cytoplasm. The purpose of tail is to make it move. The sperms moves by waving its tail from side to side.
What is sperm 12th?
Semen is the mixture of sperms and secretions from seminal vesicles, prostate gland and Cowper's (bulbo-urethral gland).
Where do male accessory reproductive glands excrete?
Male accessory reproductive gland excretions flow into the prostatic part of the urethra via the ejaculatory duct. Together with spermatozoa, they form semen. The prostate receives blood supply through branches of internal pudendal artery, inferior vesical artery and middle rectal arteries.
What is the function of the penis?
The penis is the copulatory organ of the external male genitalia. Its functions are to provide an outlet for urine and seminal fluid, as it transmits the urethra . Penis structure: Root (bulb and crus of penis), shaft (corpora spongiosa, corpus spongiosum, urethra), and glans of penis.
What is the spermatic cord?
Spermatic cord. The spermatic cord conveys the neurovascular bundle of the testes and suspends them in the scrotum. The bundle consists of arteries, nerves, pampiniform plexus, vas deferens, lymphatic vessels and tunica vaginalis to the testes and cremaster muscle.
What is the most distal portion of the corpus spongiosum?
The glans penis is the most distal portion of the corpus spongiosum. A duplicature of skin called the prepuce (foreskin) surrounds the glans and protects it. The tip of the glans is free of prepuce, and features the external urethral orifice.
What is the function of the prostate?
The prostate function is to produce fluid secreted into the urethra during ejaculation.
Which nerves are involved in innervation of the penis?
Innervation of the penis is handled by three major nerves: Pudendal nerve - provides sensory and sympathetic input involved in ejaculation. Pelvic splanchnic nerves - provide parasympathetic innervation involved in erectile function via the prostatic plexus. Ilioinguinal nerve - supplies the skin of the penile root.
Where is the epididymis located?
The epididymis is located on the posterior surface of the testis. It is made up of series of ducts and its main function is storage and maturation of spermatozoa. The epididymis is divided into three parts: the head, which is connected to the testis efferent ductules, the body and the tail.

The prostate is also where the body converts testosterone into its active form, dihydrotestosterone (DHT), which is essential for the normal development and function of the prostate.
Where is the prostate located?
The prostate is a walnut-sized gland. It is dense and firm and is located below the urinary bladder. The prostate surrounds the urethra as it exits the urinary bladder. Short ducts are present that empty from the prostate into the urethra.
What is the structure of the seminal vesicles?
The seminal vesicles have ducts that connect with the vas deferens and form a structure known as the ejaculatory duct. The ejaculatory duct passes through the prostate and drains into the urethra.
What Are the Testicles (Testes)?
The testes (or testicles) are two olive-sized oval bodies, one on the right side and one on the left side. The testes have two main functions, to produce sperm (the male reproductive cell), and to produce testosterone (the male sex hormone). The epididymides and the vasa deferentia are attached to the testicles and are important in transporting sperm cells after they develop in the testes.
What Is the Scrotum?
The scrotum is a thin sac of skin and thin muscle in which lie the testicles. The scrotum acts as a climate control system, allowing the testicles to be slightly away from the rest of the body and keeping them slightly cooler than normal body temperature for optimal sperm development. The muscles in the scrotum, called the cremasteric muscles, move the testicles slightly within the scrotum depending on the surrounding temperature.
What Are the Vas deferens and Seminal Vesicles?
Once sperm are produced, they travel through a collection area, called the epididymis, and then through a tube or duct, called the vas deferens, which then joins the seminal vesicles to form the ejaculatory duct. The seminal vesicles produce a fluid that provides nutrients for the sperm and lubricates the urethra. This fluid mixes with other fluids to create the semen.
What are the two structures that are attached to the testicles?
The term testicles includes the testes as well as the surrounding structures, such as the vas deferens and the epididymis.
What is the purpose of the urethra?
In men, the urethra provides a dual purpose, to transport urine from the bladder, and to transport the semen (sperm cells and fluid from the seminal vesicles and the prostate) out the tip of the penis. Scar tissue in this passage, called strictures, can cause urinary difficulty.
What is the prostatic fluid?
Along with the seminal vesicles, the prostate gland produces a fluid, called prostatic fluid, that contains, protects, nourishes, and supports the sperm.
What is the name of the enlargement of the prostate?
This enlargement of the prostate, called benign prostatic hyperplasia (or BPH), can be treated with medication or various surgical procedures. The prostate is also the source of a prostate specific antigen (or PSA) that is used as a blood test to detect and monitor prostate cancer.
What are the internal organs of the male reproductive system?
The internal organs of the male reproductive system, also called accessory organs, include the following: Epididymis: The epididymis is a long, coiled tube that rests on the backside of each testicle. It transports and stores sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity, ...
Where is the male reproductive system located?
Unlike the female reproductive system, most of the male reproductive system is located outside of the body. These external structures include the penis, scrotum, and testicles. Penis: This is the male organ used in sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, ...
What is the ejaculatory duct?
Ejaculatory ducts: These are formed by the fusion of the vas deferens and the seminal vesicles (see below). The ejaculatory ducts empty into the urethra. Urethra: The urethra is the tube that carries urine from the bladder to outside of the body.
What is the job of the epididymis?
It transports and stores sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity , since the sperm that emerge from the testes are immature and incapable of fertilization. During sexual arousal, contractions force the sperm into the vas deferens.
How many testes do men have?
Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for generating sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubes are responsible for producing sperm cells. The internal organs of the male reproductive system, also called accessory organs, ...
What is testosterone responsible for?

Testosterone is an important hormone during male development and maturation for developing muscles, deepening the voice, and growing body hair. Epididymis.
Which tube moves sperm from the testicles?
Epididymis. A long tube that is located near each testicle. The epididymis is the tube which moves the sperm from the testicles. Vas deferens. This is a tube in which the sperm is stored and it carries the sperm out of the scrotal sac.
What is the difference between the glans and the shaft?
The glans is the tip of the penis, while the shaft is the main part of the penis and contains the tube (urethra) that drains the bladder. All boys are born with a foreskin, or a covering over the tip of the penis. Some boys are circumcised. This means that this covering of skin is removed.
Why is the scrotum located outside the body?
The bag of skin that holds and helps to protect the testicles. The testicles make sperm and , to do this , the temperature of the testicles needs to be cooler than the inside of the body. This is why the scrotum is located outside of the body. Click image to enlarge. Testes (testicles).

The vas deferens is between the epididymis and the urethra and connects these together. Seminal vesicles. The sac-like glands that lie behind the bladder and release a fluid that forms part of semen. Prostate gland.
What is the urethra made of?
It is made up of 3 lobes: a center lobe with 1 lobe on each side. The prostate gland secretes a slightly alkaline fluid that forms part of the seminal fluid, a fluid that carries sperm. Urethra.
What is the brain signal that lets urine out of the bladder?
The brain signals the bladder muscles to tighten. This squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra. When all the signals happen in the correct order, normal urination happens. Penis.
What is the male genital system?
The male genital system consists of both external and internal parts. The external male genitalia include the penis, urethra, and scrotum.
Which organ stores and transports sperm?
The epididymis stores, matures, and transports sperm between the testes and the vas deferens, which channels sperm toward the urethra. The seminal vesicles are adjacent to the urethra and secrete a milky fluid that is ultimately discharged through the ejaculatory duct.
What is the name of the organ that transports urine from the bladder to the body?
The urethra transports the urine from the bladder, out of the male body. Semen also travels through the urethra. Each male has two scrotal pouches, which house certain parts of the internal male genitalia (epididymis, testes, and lower spermatic cords).
Why are testes important?
The testes are the most important part of internal male genitalia because they make and store sperm, as well as supply the male body with hormones, which control the development of male characteristics and reproductive organs.
