Is human fertilisation internal or external?

Answer 1

Human fertilization is internal. In humans, fertilization occurs internally within the female reproductive system. During sexual intercourse, sperm is ejaculated into the vagina, and the sperm cells travel through the cervix, uterus, and into the fallopian tubes. It is within the fallopian tubes that fertilization typically occurs when a sperm cell successfully penetrates and fertilizes an egg. After fertilization, the resulting zygote implants into the lining of the uterus, where it develops into an embryo.

Answer 2

An example of external fertilization is in fish. The eggs are dropped by the female and then the male silt is deposited on top, visible to the outside world. To view the fertilization in humans a camera would have to be inserted into the female.

Answer 3

Human fertilisation can take place at the oviduct where the ovum is being released and when the sperm swims towards it.After fertilisation,when the both sex cells fuses,the ovum will be moved to the uterus.

Answer 4

For most fish it is external; however some families have internal fertilization such as the 'livebearers', which include the guppies, mollies, platys and swords. There are others as well, such as the Halfbeaks, four eyed fishes. Many species of sharks, rays and skates also have internal fertilization.
