1) The bag of skin that holds and helps to protect the testicles. The testicles make sperm. 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.
2)In a placental mammal, an ovum is fertilized in a fallopian tube through which it travels into the uterus. An embryo is called a fetus at a more advanced stage of development and up until birth or hatching. In humans, this is from the eleventh week of gestation.

1)The main function of the testes is producing and storing sperm. They're also crucial for creating testosterone and other male hormones called androgens. Testes get their ovular shape from tissues known as lobules. Lobules are made up of coiled tubes surrounded by dense connective tissues.
2)Fallopian tube, also called oviduct or uterine tube, either of a pair of long narrow ducts located in the human female abdominal cavity that transport male sperm cells to the egg, provide a suitable environment for fertilization, and transport the egg from the ovary, where it is produced, to the central channel (lumen) .
3)The seminal vesicles are two small glands that store and produce the majority of the fluid that makes up semen. During ejaculation, the fluid from the seminal vesicles is expelled into the ejaculatory duct where it can then move on to mix with sperm and other reproductive fluids.
4) The placenta is the interface between mother and fetus. Functions of the placenta include gas exchange, metabolic transfer, hormone secretion, and fetal protection. Nutrient and drug transfer across the placenta are by passive diffusion, facilitated diffusion, active transport, and pinocytosis.
