    • Learning Objectives
      Identify the structures and functions of the female and male reproductive systems.
      Summarize the actions of the hormones that affect reproductive functioning.
      Identify the two phases of the ovarian cycle and the changes that occur in each phase.
    • Describe the phases of the menstrual cycle, their dominant hormones, and the changes that occur in each phase.
      Discuss the significance of specific female reproductive structures during childbirth.
      Identify the functions of specific male reproductive structures for reproduction.
    • FIGURE 3–1 Sexual differentiation. A, At 7 weeks’ gestation, male and female genitalia are identical(undifferentiated). B and C, By 12 weeks’ gestation, noticeable differentiation begins to occur.D and E, Differentiation continues until birth but is almost complete at term.
    • FIGURE 3–2 Physiologic changes leading to onset of puberty. A, In females, and B, in males. Solid lines illustrate stimulation of hormone production, and broken lines illustrate inhibition. Through a neurotransmitter the central nervous system stimulates the hypothalamus, which in turn produces a gonadotropin-releasing factor that causes the anterior pituitary to produce gonadotropins (FSH or LH). These hormones stimulate specific structures in the gonads to secrete steroid hormones (estrogen, progesterone, or testosterone). The rise in pituitary hormone increases hypothalamus activity. Elevated steroid hormone levels stimulate the central nervous system and pituitary gland to inhibit hormone production.

    • Hormones
      Female Hormones
      Estrogen
      Progesterone
      Prostaglandin
      Male Hormones
      Testosterone is the most important sex hormone
    • Estrogen
      Controls development of female secondary sex characteristics
      Assists in the maturation of the ovarian follicles
      Causes endometrial mucosa to proliferate following menstruation
      Causes uterus to increase in size and weight
    • Female reproductive cycle: interrelationships of hormones with the four phases of the uterine cycle and the two phases of the ovarian cycle in an ideal 28-day cycle
    • Estrogen
      Increases myometrial contractility in both the uterus and fallopian tubes
      Increases uterine sensitivity to oxytocin
      Inhibits FSH production
      Stimulates LH production
    • Progesterone
      Decreases uterine motility and contractility
      Facilitates vaginal epithelium proliferation
      Secretion of thick viscous cervical mucus
      Increases breast glandular tissue in preparation for breast feeding
    • Prostaglandin
      Prostaglandin: Increases during follicular maturation
      Causes extrusion of the ovum
    • FIGURE 3–16 Various stages of development of the ovarian follicles.
    • Follicular Phase
      Hypothalamus secretes gonadotropin-releasing hormone (GnRH)
      GnRH stimulates the anterior pituitary gland to secrete the gonadotropic hormones, follicle-stimulating hormone (FSH), and luteinizing hormone (LH)
      FSH is primarily responsible for the maturation of the ovarian follicle
    • Follicular Phase (cont’d)
      As the follicle matures, it secretes increasing amounts of estrogen
      Final maturation facilitated by LH
      The follicular phase ends with ovulation
    • Luteal Phase
      Release of ovum
      LH: Corpus luteum develops from ruptured follicle
      Secretion of progesterone increases
      Fertilized ovum able to implant into endometrium
      Secretion of human chorionic gonadotropin (hCG)
      Absence of fertilization
      Corpus luteum degenerates
      Decrease in estrogen and progesterone
      Increase in LH and FSH
    • Menstrual Phase
      Shedding of the endometrial lining
      Low estrogen levels
    • Proliferative Phase
      Enlargement of the endometrial glands
      Changes in cervical mucus
      Increasing estrogen levels
    • Secretory Phase
      Follows ovulation
      Influenced primarily by progesterone
      Increase in vascularity of the uterus
      Increase in myometrial glandular secretions
    • Ischemic Phase
      If fertilization does not occur, the ischemic phase begins
      The corpus luteum begins to degenerate
      Both estrogen and progesterone levels fall
      Escape of blood into the stromal cells of the endometrium

    • Conception and Fetal Development
    • Learning Objectives
      Compare the difference between meiotic cellular division and mitotic cellular division.
      Compare the processes by which ova and sperm are produced.
      Describe the components of the process of fertilization.
    • Describe in order of increasing complexity the structures that form during the cellular multiplication anddifferentiation stages of intrauterine development.Describe the development, structure, and functions of the placenta and umbilical cord during intrauterine life
      Identify the differing processes by which fraternal (dizygotic) and identical (monozygotic) twins are formed
      Summarize the significant changes in growth and development of the fetus in utero at 4, 6, 12, 16, 20, 24, 28, 36, and 40 weeks’ gestation.
    • Mitosis
      Process of cellular division
      Results in daughter cells that are exact copies of the original cell
      Identical to parent cell and to each other
      Contain a full set of chromosomes or genetic material
      Refered to as diploid cells
      Somatic cells continue to reproduce and replace each other
    • Mitosis
      The cell undergoes several changes ending in cell division
      At the last phase of cell division, a furrow develops in the cell cytoplasm
      The parent cell divides into two daughter cells
      Each daughter cell has its own nucleus
      They are identical to the parent cell
      They have the same diploid number of chromosomes (46) and same genetic makeup as the cell from which they came
    • Meiosis
      Type of cell division that produces reproductive cells called gametes (sperm and ova) - each cell contains half genetic material of parent cell (haploid)
    • Meiosis (cont’d)
      Meiosis consists of two successive cell divisions
      First division: Chromosomes replicate
      Second division: Chromatids of each chromosome separate and move to opposite poles of each of the daughter cells
      Cellular division results in formation of four cells
      Each cell contains haploid number of chromosomes
      Daughter cells contain only half the DNA of normal somatic cell
    • Comparison of Meiosis and Mitosis
    • FIGURE 7–1 Gametogenesis involves meiosis within the ovary and testis. A, During meiosis, eachoogonium produces a single haploid ovum once some cytoplasm moves into the polar bodies.B, Each spermatogonium produces four haploid spermatozoa.
    • Oogenesis
      Process that produces the female gamete, called an ovum (egg), that begins to develop early in the fetal life of the female
      Ovaries begin to develop early in the fetal life of the female
      All ova that female will produce in her lifetime are present at birth - ovary gives rise to oogonial cells, which develop into oocytes
      During puberty: Mature primary oocyte continues through first meiotic division in ovary
      Haploid cells released at ovulalion
    • Oogenesis
      The first meiotic division
      Two cells of unequal size produced with same number of chromosomes
      One cell is secondary oocyte, other is minute polar body
      Secondary oocyte and polar body each contain 22 double-structured autosomal chromosomes and one double-structured sex chromosome (X)
      During puberty: Mature primary oocyte continues through first meiotic division in ovary
    • Spermatogenesis
      Production of the male gamete, or sperm, during puberty
      The spermatogonium (primordial germ cell)
      Begins with complete set of genetic material - diploid number of chromosomes
      Cell replicates before it enters first meiotic division
      Cell is now primary spermatocyte
      During second meiotic division, divide to form four spemiatids, each with haploid number of chromosomes
    • Spermatogenesis (cont’d)
      During the first meiotic division
      Spermatogonium forms two cells called secondary spermatocytes
      Each contains 22 double-structured autosomal chromosomes and either double-structured X sex chromosome or double-structured Y sex chromosome
    • Preparation for Fertilization
      Preparation is the first component of fertilization
      Ovum released into fallopian tube - viable for 24 hours
      Sperm deposited into vagina - viable for 48 to 72 hours (highly fertile for 24 hours)
      Sperm must undergo capacitation and acrosomal reaction
      Sperm penetration causes a chemical reaction that blocks more sperm penetration
    • Moment of Fertilization
      Sperm penetration causes chemical reaction that blocks more sperm penetration
      Sperm enters ovum, chemical signal prompts secondary oocyte to complete second meiotic division
      True moment of fertilization occurs as nuclei unite
      Chromosomes pair up to produce diploid zygote
      Each nucleus contains haploid number of chromosomes (23)
    • Moment of Fertilization (cont’d)
      Union restores diploid number (46)
      Zygote contains new combination of genetic material
      Sex of zygote determined at moment of fertilization
      Two chromosomes of twenty-third pair (sex chromosomes) - either XX or XY - determine sex of individual
      Females have two X chromosomes, males have an X and a Y chromosome

    • FIGURE 7–3 During ovulation the ovum leaves the ovary and enters the fallopian tube. Fertilizationgenerally occurs in the outer third of the fallopian tube. Subsequent changes in the fertilizedovum from conception to implantation are depicted.
    • Cell Multiplication
      Rapid mitotic division - cleavage
      Blastomeres grow to morula (solid ball of 12 to 16 cells) - solid ball of 12 to 16 cells
      Morula divides into solid mass (blastocyst); surrounded by outer layer of cells (trophoblast)
      Implantation; occurs in 7 to 10 days
    • Cell Differentiation
      10 to 14 days (ectoderm, mesoderm, and endoderm) from which all tissues, organs, and organ systems develop
      Blastocyst differentiates into three primary germ layers (ectoderm, mesoderm, and endoderm)
      All tissues, organs, and organ systems develop from these primary germ cell layers
      Embryonic membranes form at implantation
      The chorion and the amnion
    • Derivation of Body Structures from Primary Cell Layers
    • Cell Differentiation
      Amniotic Fluid: Created when amnion and chorion grow and connect andform amniotic sac to produce fluid
      Yolk sac
      DeveIops as part of the blastocyst
      Produces primitive red blood cells
      Soon incorporated into the umbilical cord
    • FIGURE 7–4 Formation of primary germ layers. A, Implantation of a 7 1/2-day blastocyst in which thecells of the embryonic disc are separated from the amnion by a fluid-filled space. The erosion of the endometrium by the syncytiotrophoblast is ongoing. B, Implantation is completed by day 9, and extraembryonic mesoderm is beginning to from a discrete layer beneath the cytotrophoblast. C, By day 16 the embryo shows all three germ layers, a yolk sac, and an allantois (an out pouching of the yolk sac that forms the structural basis of the body stalk, or umbilical cord). The cytotrophoblast and associated mesoderm have become the chorion, and chorionic villi are developing.
    • Cell Differentiation
      Ectoderm
      Mesoderm
      Endoderm - differentiation of endoderm results in formation of epithelium lining respiratory and digestive tracts
    • FIGURE 7–5 Endoderm differentiates to form the epithelial lining of the digestive and respiratory tractsand associated glands.
    • FIGURE 7–6 Early development of primary embryonic membranes. At 4 1/2 weeks, the decidua capsularis (placental portion enclosing the embryo on the uterine surface) and decidua basalis (placental portion encompassing the elaborate chorionic villi and maternal endometrium) are well formed. The chorionic villi lie in blood-filled intervillous spaces within the endometrium. The amnion and yolk sac are well developed.
    • Umbilical Cord
      Develops from amnion
      Body stalk attaches embryo to yolk sac, fuses with embryonic portion of placenta
      Provides pathway from chorionic villi to embryo
      Contains two arteries and one vein; surrounded by Wharton’s jelly to protect vessels
      Wharton’s jelly: Specialized connective tissue
      Protects blood vessels
      Function of umbilical cord: Provides circulatory pathway to embryo
    • Placenta
      Placental development
      Begins at third week of embryonic development
      Develops at site where embryo attaches to uterine wall
      Function: Metabolic and nutrient exchange between embryonic and maternal circulations
      Placenta has two parts
      Maternal
      Fetal
    • Placenta
      Maternal portion
      Consists of deciduas basalis and its circulation
      Surface appears red and flesh-like
      Fetal portion
      Consists of the chorionic villi and their circulation
      The fetal surface of the placenta is covered by the amnion
      Appears shiny and gray
    • FIGURE 7–8 Maternal side of placenta (Dirty Duncan).
    • FIGURE 7–9 Fetal side of placenta (Shiny Shultz).
    • FIGURE 7–10 Vascular arrangement of the placenta. Arrows indicate the direction of blood flow. Maternal blood flows through the uterine arteries to the intervillous spaces of the placenta and returnsthrough the uterine veins to maternal circulation. Fetal blood flows through the umbilical arteries into the villous capillaries of the placenta and returns through the umbilical vein to the fetal circulation.
    • FIGURE 7–11 Fetal circulation. Blood leaves the placenta and enters the fetus through the umbilicalvein. After circulating through the fetus, the blood returns to the placenta through the umbilical arteries. The ductus venosus, the foramen ovale, and the ductus arteriosus allow the blood to bypass the fetal liver and lungs.
    • Figure 7–7 A, Formation of fraternal twins. (Note separate placentas.) B, Formation of identical twins.
    • Figure 7–7 (continued) A, Formation of fraternal twins. (Note separate placentas.) B, Formation of identical twins.
    • Identical Twins
      Develop from single fertilized ovum
      Of same sex and have same genotype
      Identical twins usually have common placenta; monozygosity is not affected by environment, race, physical characteristics, or fertility
      Both fetus are same sex with same characteristics
      Single placenta
    • Identical Twins
      Number of amnions and chorions present - depends on timing of division
      Division within 3 days of fertilization; two embryos, two amnions, and two chorions will develop
      Division about 5 days after fertilization
      Two embryos develop with separate amniotic sacs
      Sacs will eventually be covered by a common chorion
      Monochorionic-diamniotic placenta
    • Identical Twins (cont’d)
      If amnion already developed, division approximately 7 to 13 days after fertilization
      Two embryos with common amniotic sac and common chorion
      Monochorionic-monoamniotic placenta
      Occurs about 1% of the time
    • Fraternal Twins
      Also referred to as dizygotic
      Arise from two separate ova fertilized by two separate spermatozoa
      Two placentas, two chorions, and two amnions
      Sometimes placentas fuse and appear to be one
      Fraternal twins
      No more similar to each other than singly bom siblings
      May be of same or different sex
