2 Reproductive System Overview Reproduction: Making New OffspringMales Make Sperm (Male Sex Cell)23 Chromosomes donated to child from FatherFemales Make Eggs (Female Sex Cell)23 Chromosomes donate to child from MotherConception: When the Sperm Fertilizes the EggInternal process (Mammal)
3 Reproductive System Overview: Hormones Hormone: Natural Chemicals that act as messengers which help the body work properly. These flow with the blood in the blood stream.Sex Hormones: Hormones (gender specific) that trigger change in the body (like puberty), and are responsible for the production of Sex Cells.Male Sex Hormone: TestosteroneFemale Sex Hormone: Estrogen, Progesterone
4 Reproductive Terminology Genital: The parts of the reproductive system that are outside of the body.Semen: Thick, Whitish Fluid that carries and nourishes Sperm.Gland: The parts of the body which produce important fluidsGonad: The sex glands. Gonads make Sex Cells (Eggs & Sperm) and Sex HormonesMale: TesticlesFemale: Ovaries
7 Male Reproductive System: Organs & Functions Penis: The organ of the male genitals. Responsible for transmission of semen to the Vagina.Testicle: Male gonads. Testicles are found in the scrotum and they make sperm and produce testosterone. (Also called testes)Scrotum: the sac that holds the testes and is responsible for regulating temperature.
8 Male Reproductive System: Organs & Functions Epididymis: Coiled tube, connected to the testicle. Once sperm are made, they are stored for maturation in the Epididymis.Vas Deferens: The tube that carries mature sperm from the Epididymis into the body.Seminal Vesicle: Glands on each of the vas deferens that make some of the liquid part of semen
9 Male Reproductive System: Organs & Functions Prostate Gland: Gland under the bladder that makes some of the liquid part of the semen.Cowper’s Gland: Glands attached to the Urethra that make a discharge which lines the urethra during an erection. This fluid protects the sperm as they leave the body.Urethra: the tube that carries Semen (and urine) out of the body.
10 Male Reproductive System: The Penis—a Deeper Look Shaft: The long, skin-covered part of the penisHead: The nerve-filled part at the end of the penis (glans penis)Foreskin: The sleeve of skin around the Head of the penis. It is sometimes removed.Circumcision: An operation to remove the foreskin from the penis.Flaccid: A state in which the penis is not erectErection: the penis fills with blood becoming larger and harder, preparing for ejaculation.
11 The Travel Path of the Sperm Testicle: Sperm ProductionEpididymis: Sperm MaturationVas DeferensProstate & Seminal Vesicle: Sperm to SemenUrethra & Cowper’s GlandPenis...and then...
12 EJACULATION! Ejaculation: The release of Semen from the Penis. Ejaculate: syn. SemenPre-Ejaculate: Fluid secreted by Cowper’s Gland40 Million to 600 Million Sperm per each EjaculationOccurs at average speed of 28 mphIn a lifetime, men will produce 14 gallons of Sperm
15 Female Reproductive System: Internal Organs & Functions Fallopian Tubes (Uterine Tubes): The ducts that carry an Ovum (Egg) from the Ovary to the UterusOvary: Female Gonad. Glands on either side of the Uterus where egg cells are stored and female hormones are made.
16 Female Reproductive System: Internal Organs & Functions Vagina: The “tube” leading from the Uterus to the outside of the female’s body. This is also called the Birth CanalCervix: The opening of the Uterus to the VaginaUterus: The organ where the fetus grows until birth.
17 Female Reproductive System: External Organs & Functions Clitoris: The part of the female genitals that is nerve-packed—much like the penis head.Labia (Majora & Minora): Folds of skin in the fmale genitals that protect the openings to the Urethra and Vagina.Hymen: The think skin that partly covers the opening to the vagina. It may be absent in some females.
18 Female Reproductive System: Other tid-bits Vulva: Term for Female GenitalsUrethra: Tube that cares urine out of the bodyOvum: syn. EggDischarge: Liquid/Fluid. Usually describes normal wetness of the vagina or abnormal wetness that may come from an infection in the Penis or Vagina
19 The Travel Path of the Egg Ovary: Storage & MaturationFallopian Tube: Egg Carried to the Uterus--Conception or Menstruation–Uterus: Egg embeds in Uterine LiningCervix:Vagina (Birth Canal)
20 Menstruation: YOUR PERIOD Menstruation: Process in which the Uterine Lining is broken down and discharged. Also called the Period.Menstruation occurs on a 28 day (averaged) Cycle.Days 1-5: The Uterine Lining is discharged from the bodyDays 6-13: The Uterine Lining begins to build back up in preparation for Ovulation.Days 14-17: OVULATION: the Ovum travels through the Fallopian Tube to be fertilized by the Sperm.Days 18-28: If the egg is not fertilized, the Uterine Lining begins breaking down in preparation for expulsion.
21 Menstruation: YOUR PERIOD Most girls will have their first period between the ages of 10-16Most girls will be about 100 lbs. when it happens.The PERIOD will last between 2-7 daysTampons (inserted into the Vagina) and Pads should be changed often, as they can be Odorous...and it’s not a bad idea to carry an extra with you if you think your PERIOD is coming.You CAN be active during your PERIODIn fact, being active can help alleviate Cramps and BloatingThe average cycle is 28 days—once a month—but can varyAn irregular period is normal for Pubescent
