| Term | Definition |
|---|---|
| Corpus Luteum | what is left of a follicle after it ruptures and releases an egg |
| Epididymis | small organ attached to testis in which sperm mature and are stored |
| Fallopian Tube | tube connecting an ovary to the uterus, also called oviduct |
| Fertilization | process in which a sperm cell fuses with an egg cell to form a new organism |
| Follicle Stimulating Hormone (FSH) | hormone that makes the ovary release estrogen and one ovum at a time |
| Follicular Phase | 1st phase of menstrual cycle when low estrogen stimulates FSH and LH, making the egg mature in follicle |
| Implantation | process in which a blastocyst attaches to the uterine wall |
| Luteal Phase | 3rd phase of menstrual cycle, blood vessels grow into the uterine lining to prepare for nourishing a baby. Only time when women are fertile |
| Luteinizing Hormone (LH) | hormone produced by pituitary gland that spurs the reproductive system into action |
| Menopause | cessation of menstrual cycles |
| Menstrual Cycle | series of natural changes in hormone production and uterine structures to prepare for potential pregnancy |
| Menstruation | 4th phase of menstrual cycle. Unfertilized egg and uterine wall is shed |
| Ovary | A female organ that makes the ova |
| Ovulation | 2nd phase of menstrual cycle, estrogen causes a sudden release of LH which cause the follicle to rupture and release an egg |
| Ovum | egg |
| Penis | male organ that carries the duct from the transfer of sperm |
| Puberty | stage of development in which the reproductive organs mature and the person becomes physically able to reproduce |
| Scrotum | sac that holds the testes |
| Secondary Sexual Characteristics | any of the body characteristics that develop during adolescence not directly related to reproduction |
| Female Secondary Sexual Characteristics | hips widen, breasts develop |
| Male Secondary Sexual Characteristics | voice lowers, facial hair grows |
| Semen | fluid that carries sperm out of the body |
| Sexually Transmitted Disease | disease spread by sexual relations, especially those outside of marriage |
| Sperm | male reproductive cell |
| Urethra | in males, it not only carries urine from the bladder, but also semen |
| Uterus | Where the zygote implants |
| Vagina | an elastic muscular canal that extends from the vulva to the cervix; birth canal |
| Vas Deferens | tube that carries sperm out of the testes |
| Zygote | A fertilized egg |
