fertility. The male gonads are the testes; they are the source of spermatozoa and also of male sex hormones called androgens. The other genital organs are the epididymides; the ductus, or vasa, deferentia; the seminal vesicles; the ejaculatory ducts; and the penis; as well as certain accessory structures, such as the prostate and the ...
Plant reproductive system, any of the systems, sexual or asexual, by which plants reproduce. Asexual reproduction results in offspring that are identical to the parent plant. Sexual reproduction involves new genetic combinations and results in offspring that are genetically different from the parent plants.
The additional tissue, reproductive tissue, usually becomes separated from the individual to form a new, independent organism. This article describes the reproductive systems in metazoans (multicelled animals) from sponges to mammals, exclusive of humans.
All living things reproduce, or create offspring. Animals’ offspring are often called babies. The body parts that allow animals to create babies belong to the reproductive system.
Human reproductive system - Female Anatomy, Hormones, Reproduction: The female gonads, or sexual glands, are the ovaries; they are the source of ova (eggs) and of the female sex hormones estrogens and progestogens.
Reproductive system disease, any of the diseases and disorders that affect the human reproductive system. They have a wide range of causes, from genetic abnormalities to infections, and affect individuals of all ages. Learn about the types, causes, and treatment of reproductive system disease.
Animal reproductive system - Male Systems, Hormones, Reproductive Organs: In anurans, amniotes (reptiles, birds, and mammals), and even some teleosts, testes are composed largely of seminiferous tubules—coiled tubes, the walls of which contain cells that produce sperm—and are surrounded by a capsule, the tunica albuginea.
Organs of the human reproductive system. In a male, the scrotum, a pouch of skin, is divided into two sacs, each containing a testis and its associated epididymis. Tubules within the testes contain sperm cells at different stages of development.
Uterus, an inverted pear-shaped muscular organ of the female reproductive system, located between the bladder and the rectum. It functions to nourish and house a fertilized egg until the fetus, or offspring, is ready to be delivered.
