Is human fertilisation internal or external?
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.

After fertilization, the resulting zygote implants into the lining of the uterus, where it develops into an embryo.
