The reproductive system is a collection of organs that work together for the purpose of producing a new life


Spermatogenesis is the process in which spermatozoa are produced from male primordial germ cells by way of mitosis and meiosis.


    Oogenesis (the creation of an ovum, an egg cell) takes one cell and makes four. But only one cell is eventually used as a gamete. It would be inefficient to allow the three other cells equal amounts of cytoplasm or nutrients if only one of those cells is the important one. Therefore, all resources from the original cell goes to the ovum, while the three other cells are just a depository for DNA. The three other cells are called polar bodies and will then die soon after.


Sexually transmitted infections (STI), also referred to as sexually transmitted diseases (STD) and venereal diseases (VD), are infections that are commonly spread by sex, especially vaginal intercourse, anal sex and oral sex. Most STIs initially do not cause symptoms.[1] This results in a greater risk of passing the disease on to others. Symptoms and signs of disease may include: vaginal discharge, penile discharge, ulcers on or around the genitals, and pelvic pain. STIs acquired before or during birth may result in poor outcomes for the baby. Some STIs may cause problems with the ability to get pregnant.


Sexually transmitted diseases (STDs) are caused by infections that are passed from one person to another during sexual contact.

These infections often do not cause any symptoms. Medically, infections are only called diseases when they cause symptoms. That is why STDs are also called "sexually transmitted infections." But it’s very common for people to use the terms "sexually transmitted diseases" or "STDs," even when there are no signs of disease.
