Answer:
The male reproductive system consists of external organs. ... The female reproductive system primarily consists of internal organs. The female gamete, ovum, is produced in the ovaries and is released monthly to travel to the uterus via the Fallopian tubes. Another key variable in the composition of men versus women stems from the sex chromosomes, which form one of the 23 pairs of human chromosomes in each cell. Generally, females have two X chromosomes in their pair, while males have one X and one Y chromosome.
Explanation:
The male sex organs work together to produce and release semen into the reproductive system of the female during sexual intercourse. The male reproductive system also produces sex hormones, which help a boy develop into a sexually mature man during puberty. The female reproductive system includes the ovaries, Fallopian tubes, uterus, vagina, accessory glands, and external genital organs.
