The male reproductive system includes the scrotum, testes, spermatic ducts, sex glands, and penis. These organs work together to produce sperm, the male gamete, and the other components of semen. These organs also work together to deliver semen out of the body and into the vagina where it can fertilize egg cells to produce offspring.

How many uterus does a woman have?
In a female fetus, the uterus starts out as two small tubes. As the fetus develops, the tubes normally join to create one larger, hollow organ — the uterus. Sometimes, however, the tubes don't join completely. Instead, each one develops into a separate structure.
How do the reproductive system and endocrine system work together to maintain a healthy body?
Endocrine glands in the reproductive system produce sex hormones that are responsible for secondary sex characteristics in men and women. Sex hormones also contribute to the production of sex cells, or gametes. Female sex hormones regulate ovulation, the menstrual cycle, and pregnancy.

What is the male reproductive system?
Male Reproductive Anatomy. In the male reproductive system, the scrotum houses the testicles or testes (singular: testis), including providing passage for blood vessels, nerves, and muscles related to testicular function. The testes are gonads, and they produce sperm (the male gametes) and some reproductive hormones.
What are the three reproductive structures?
In general, the reproductive structures in humans can be divided into three main categories: gonads, internal genitalia and external genitalia. The gonads are the organs in which gametes, the cells that fuse in fertilization to form new individuals, develop and mature. All other reproductive structures are called genitalia, or genitals.
How much sperm is in an ejaculate?
An ejaculate (a single emission of sperm) will contain from two to five milliliters of fluid with from 50–120 million sperm per milliliter. Figure 2.
Where do oviducts go?
The oviducts, or fallopian tubes, extend from the uterus in the lower abdominal cavity to the ovaries, but they are not in contact with the ovaries. The lateral ends of the oviducts flare out into a trumpet-like structure and have a fringe of finger-like projections called fimbriae, illustrated in Figure 4b. When an egg is released at ovulation, the fimbrae help the non-motile egg enter into the tube and passage to the uterus. The walls of the oviducts are ciliated and are made up mostly of smooth muscle. The cilia beat toward the middle, and the smooth muscle contracts in the same direction, moving the egg toward the uterus. Fertilization usually takes place within the oviducts and the developing embryo is moved toward the uterus for development. It usually takes the egg or embryo a week to travel through the oviduct. Sterilization in females is called a tubal ligation; it is analogous to a vasectomy in males in that the oviducts are severed and sealed.
What are the walls of a seminiferous tubule made of?
The walls of the seminiferous tubules are made up 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.

Male gonads are called testicles. These two organs are composed of numerous coiled tubes (seminiferous tubules) where we find the cells that produce the spermatocytes (precursors of sperm cells). Additionally, it is in the testicles where the male hormone, testosterone, is produced and released in the bloodstream.
What is the difference between a male and female gamete?
The male gamete is sperm and the female gamete is the egg. Sexual reproduction is the fusion or fertilisation of the two male and female gametes to produce a fertilised egg or zygote. The fertilised egg goes on to divide many times to form a ball of cells.

Where are the cowper glands located?
Bulbourethral glands: The bulbourethral glands, or Cowper’s glands, are pea-sized structures located on the sides of the urethra , just below the prostate gland. These glands produce a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.
