The female reproductive system begins with the [1], where immature eggs, or oocytes, are stored from birth. Each month, one of these immature eggs undergoes [2], a process in which it matures and is released from the [3]. The released mature egg is then captured by finger-like projections called [4], which guide it into the [5]. If fertilization occurs, it typically takes place in the [6]. A couple of days after fertilization the fertilized egg may become embedded in the [7] of the uterus resulting in a pregnancy.  If fertilization does not occur, the thickened lining of the [8] is shed during [9], which marks the beginning of a new menstrual cycle. Menstrual blood and tissue are expelled from the body through the [10].

Sperm production begins in the [1], a pair of oval-shaped organs located within the scrotum. After their formation, sperm travel through a coiled tube called the [2], where they mature. The [3], which is a muscular tube, carries sperm from the epididymis to the [4]. During sexual arousal, sperm and secretions from the [5] combine to form a milky fluid called seminal fluid. Just before ejaculation, sperm and seminal fluid mix with additional secretions from the [6] to form semen with active sperm. Prior to ejaculation the [7] secretes a solution to clean out the urethra. Finally, during ejaculation, semen is expelled from the body through the [8], which serves a dual role in the male reproductive and urinary systems. Success of ejaculation is aided by erection of the penis, which occurs due to the flow of blood into the [9] and the [10].
