1 Lesson 15.1 Reproduction and Development of the Human Reproductive Systems Chapter 15: The Male and Female Reproductive Systems

2 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. SRY gene is present –7th week of development male sex organs begin to development No SRY gene –8th week of development female sex organs begin development Fetal development

3 Lesson 15.2 Male Reproductive System Anatomy and Physiology Chapter 15: The Male and Female Reproductive Systems

4 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Male Reproductive Anatomy

5 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. scrotum and testes –sperm production mature in epididymis penis –delivers sperm –contains erectile tissue Male Reproductive Anatomy

6 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. ducts –ductus deferens –ejaculatory duct accessory glands and semen –seminal glands –prostate gland –bulbourethral glands Male Reproductive Anatomy

7 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. sperm formation –spermatogenesis –begins at puberty, ends…@DEATH sexual response –Erection-erectile tissue filled with blood –Ejaculation- propulsion of semen Male Reproductive Physiology

8 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Sperm Cell

9 Lesson 15.3 Female Reproductive System Anatomy and Physiology Chapter 15: The Male and Female Reproductive Systems

10 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Female Reproductive System Anatomy

11 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. ovaries –oocyte egg cell –ovulation release of egg from ovary Female Reproductive System Anatomy

12 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. ducts –uterine tubes connect ovary to uterus uterus – womb –endometrium –cervix Female Reproductive System Anatomy

13 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. vagina –birth canal external genitalia –labia –clitoris mammary glands –lactation Female Reproductive System Anatomy

14 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. oocyte production process begins before birth primary oocyte secondary oocyte –polar bodies Oogenesis

15 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. menstrual cycle ovarian cycle –maturation and release of oocyte –Days 1-14 uterine cycle –uterus readies for implantation The Female Sexual Cycle

16 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Follicular phase primary follicle –pituitary gland releases FSH and LH –ovulation Luteal phase –Secretes LH –Corpus Luteum –disintegrates after 10 days (if no fertilization) The Ovarian Cycle

17 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. menstrual phase –days 1-5; endometrium breaks down and sheds proliferative phase –days leading to ovulation; endometrium grows back secretory phase –Ovulation  endometrium prepares to nourish embryo The Uterine Cycle

18 Lesson 15.4 Fertilization, Pregnancy, and Birth Chapter 15: The Male and Female Reproductive Systems

19 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. 1.fertilization of oocyte 2.pregnancy 3.childbirth 4.lactation Fertilization, Pregnancy, and Birth

20 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. journey of sperm –vagina, uterus, uterine tube –capacitation can take 10 hours sperm penetration –zona pellucida –acrosomal enzymes Fertilization of the Oocyte

21 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. only 1 sperm is required for fertilization –more than 1 = death of oocyte –chemistry of zona pellucida changes after sperm entry Sperm entry, completion of meiosis and fertilization –Contact with ZP activates Acrosomal enzymes Fertilization of the Oocyte Nejron Photo/Shutterstock.com

22 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. lasts approximately 265 days –(if by last period, 9 months-1 week or 280 days) from fertilization to implantation development of placenta, embryo, and fetus Pregnancy

23 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. cell stages –Zygote- fertilized egg, less than 16 cells –Morula- solid ball,16 cells –Blastocyst- sheds zona pellucida, enters uterine cavity, fluid-filled cavity, develops trophoblast implantation –Day 15 of uterine cycle; blastocyst binds to endometrium –High hCG retains endometrium From Fertilization to Implantation

24 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. From Fertilization to Implantation

25 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Embryo –Implantation-8 weeks Fetus –8+ weeks of development Placenta –supplies nutrients to embryo and fetus Development of Placenta, Embryo, and Fetus

26 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Parturition = birth; prostaglandins from placenta stimulate contractions –Contractions last1 min every 2-3 minutes oxytocin stages of labor –Dilation- full is 10 cm –Expulsion- full dilation  delivery –delivery of placenta Detaches from uterine wall Childbirth

27 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. production of breast milk activation of milk-producing cells –prolactin delivery of milk through ducts to nipple –oxytocin Lactation

28 Lesson 15.5 Disorders and Diseases of the Reproductive System Chapter 15: The Male and Female Reproductive Systems

29 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. male infertility –low sperm count –erectile dysfunction female infertility –failure to ovulate –inability of egg to reach uterine tube –lack of implantation Infertility

30 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. treatment for infertility –lifestyle changes –drugs to induce ovulation –surgery to correct anatomical issues in vitro fertilization –oocyte and sperm combined outside mother’s body Infertility

31 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. prostate cancer –PSA test cancers of the female reproductive tract –uterine cancer –ovarian cancer –cervical cancer –breast cancer Cancers of the Reproductive System
