Semen consists of 2 components: the sperm component and a fluid component. Sperm is produced by the testicles. The fluid component is secreted by the prostate gland, bulbourethral (or Cowper's) glands, and seminal vesicles. The fluid component provides nutrition for the sperm as well as neutralizes the acidic environement of the urethra of the penis and the vagina of the female.

What are the repoductive structures?
Reproductive structures are the parts of an organism involved in sexual reproduction, including organs such as testes and ovaries in animals, and flowers and cones in plants. These structures are responsible for producing gametes (sperm and eggs) in animals, and pollen and ovules in plants, which are necessary for fertilization and the production of offspring.
What structures within the ovary are responsible for production of each hormone?
The ovarian follicles produce estrogen, primarily in the form of estradiol. The corpus luteum, a temporary endocrine structure that forms after ovulation, is responsible for producing progesterone.
What kind of structure do vertical hyphae produce?
Vertical hyphae produce reproductive structures such as sporangia, conidiophores, or basidiocarps, which are responsible for producing spores and propagating the fungus. These structures can project above the surface of the substrate to aid in spore dispersal.
What organ system contains the mammary papillae?
The mammary papillae are part of the reproductive system in mammals, specifically in the female mammary glands. These structures are responsible for producing and secreting milk for feeding offspring.
What plant part grows out of the stem?

Is it normal for a 9 year old to have semen?

What are Sporgangia?
Sporgangia are reproductive structures produced by certain types of algae and fungi. They are responsible for releasing spores, which allow these organisms to reproduce and spread.
Which cells or structures are associated with asexual reproduction in fungi?
Asexual reproduction in fungi is associated with structures such as spores, conidia, and budding cells. These structures are responsible for producing genetically identical offspring without the need for fertilization.
What is the singular of mitochondria?

Can a kid lose all his semen?

What is the name of the exocrine gland near the male urethra?
The exocrine gland near the male urethra is called the prostate gland. It is responsible for producing prostatic fluid, which is a component of semen.
What does Fern prothallia sporangia mean?
Fern prothallia are small heart-shaped structures that produce reproductive structures called sporangia. Sporangia are responsible for producing spores in ferns, which can develop into new fern plants.
What structures add volume to the fluid of semen?
drink a lot of milk...
