A fundamental process in the cycle of life, involving the intricate coordination of male and female reproductive organs
Male and female reproductive organs
Exhibit remarkable adaptations and functions tailored to their respective roles in the reproductive process
Testes
The primary reproductive organs in males, responsible for the production of sperm cells
Spermatogenesis
The process of sperm production within the seminiferous tubules of the testes
Epididymis
A coiled tube located on the surface of each testis, responsible for storing and transporting sperm cells, and facilitating their maturation
Accessory glands
Glands in the male reproductive system (prostate gland, seminal vesicles, bulbourethral glands) that contribute fluids to semen to nourish and protect the sperm
Urethra
A tube that carries urine from the bladder to the external opening, and also serves as a passageway for semen during ejaculation in males
Prostate gland
A small gland located below the bladder and surrounding the urethra, producing a fluid that helps nourish and protect the sperm, increase their motility, and enhance their ability to fertilize an egg
Seminal vesicles
Two small glands located behind the bladder, connected to the vas deferens, producing a fluid rich in fructose, prostaglandins, and other substances that provide energy for the sperm, help neutralize acidity, and enhance their motility and viability
Bulbourethral glands
Also known as Cowper's glands, they are small glands located beneath the prostate gland, producing a clear, viscous fluid that helps lubricate and cleanse the urethra, neutralizing any remaining acidity and preparing it for the passage of sperm during ejaculation
Ovaries
The main reproductive organs in females, responsible for producing the female gametes (eggs or ova)
Follicles
Microscopic structures within the ovaries that house immature eggs, nurturing and supporting their development until they are released during ovulation
Fallopian tubes
Slender tubes that connect the ovaries to the uterus, capturing the released egg during ovulation and providing a pathway for it to travel towards the uterus, where fertilization typically occurs
Uterus
A hollow, muscular organ where fertilized eggs implant and develop into embryos, with a lining (endometrium) that undergoes cyclic changes during the menstrual cycle to prepare for pregnancy
Vagina
A muscular canal that connects the uterus to the external genitalia, serving as a passageway for menstrual flow, receiving the penis during sexual intercourse, and acting as the birth canal during childbirth
Cervix
The lower part of the uterus that connects it to the vagina, producing cervical mucus that changes consistency throughout the menstrual cycle, affecting sperm transport and acting as a protective barrier against infections, and dilating during childbirth to allow the passage of the baby
External genitalia (vulva)
Structures that protect the internal reproductive organs and play a role in sexual arousal and pleasure, including the labia majora, labia minora, clitoris, and vaginal opening
