Question

Explain the process in sexual intercourse in human

Answer 1

Sexual intercourse, or copulation, is the deposition of sperm into a female via a male intromittent organ. In humans, the intromittent organ is the penis, and sperm are deposited into the vagina, where they make their way to towards the uterus to fertilize an egg. However, sexual intercourse is almost as varied as the animal kingdom itself, and occurs in some form or another in most of the large groups of organisms. From the smallest organisms to the largest, sexual intercourse is simply the process of delivering sperm into the female, although the process varies widely.As opposed to external fertilization, internal fertilizationthrough sexual intercourse increases the change that fertilization will occur among the gametes. During external fertilization, gametes are broadcast into the environemtn, and must find their way to each other through shear numbers. Organsims that reproduce using this method must time the release of their gametes to maximize the production of new offspring. Sexual intercourse not only localizes the deposit of sperm, but greatly reduces the distance and area a sperm must cover to find an egg. Beyond the penis or other intromittent organ entering the female and depositing sperm, the process of sexual intercourse varies widely by animal.
