| Fallopian tubes (oviducts) | Tubes that transport the egg from the ovary to the uterus; fertilisation usually occurs here |
| Seminal vesicle | Glands that produce a fluid rich in sugars that provides energy for sperm. |
| Prostate gland | A gland that produces fluid that helps nourish and transport sperm. |
| Urethra | A tube that carries urine and, in males, semen out of the body. |
| Scrotum | A pouch of skin that holds and protects the testes and regulates their temperature. |
| Bulbourethral glands | Small glands that produce a clear fluid that lubricates the urethra and helps protect sperm during ejaculation. |

| Vas (ductus) deferens | A muscular tube that transports mature sperm from the epididymis to the urethra. |
| Endometrium | The lining of the uterus that thickens to support a pregnancy. |
| Fimbriae | Finger‑like projections at the end of the fallopian tubes that help guide the released egg into the tube. |
| Ovaries | Female reproductive organs that produce eggs and hormones such as oestrogen and progesterone. |
| Penis | The external male reproductive organ that delivers sperm. |
| Seminiferous tubules | Tiny tubes inside the testes where sperm are produced. |

| Vagina | A muscular canal that receives the penis during intercourse and serves as the birth canal. |
| Vulva | The external female genital area, including the labia and clitoris. |
| Ejactulatory duct | Duct for transporting semen (sperm + glandular secretions) |
| Myometrium | Outer layer of the uterus, consisting of thick layers of smooth muscle. Stretches during pregnancy and contracts during labour. |
