Pathway of sperm

The ovary comprises an outer covering of cuboidal epithelium that is superficial to a dense connective tissue covering called the tunica albuginea. The corpus spongiosum , a raised ridge on the erect penis, is a smaller chamber that surrounds the spongy, or penile, urethra. The key male reproductive organs include the testes, epididymis, urethra, vas deferens, prostate gland, seminal vesicle, and penis. The internal reproductive anatomy includes the uterus , two ovaries , two fallopian tubes , the urethra, the pubic bone , and the rectum. The two oviducts join to form a triangular organ called uterus, where an embryo can grow. At the end of sexual intercourse, they travel along the vas deferens and mix with fluids made by the prostate gland and seminal vesicle.
