Each of the four female reproductive hormones (FSH, LH, estrogen & progesterone) have specific roles or functions to complete to ensure a successful pregnancy. While these hormones may be released at different time during an average 28 day cycle there are key times in the cycle where their release is critical in ensuring a successful pregnancy. Which of the following lists the order of hormonal release from days 0-28 required to support the fertilization and implantation of the ovum? Select one: a. FSH, LH, estrogen, progesterone b. FSH, estrogen, progesterone, LH c. LH, FSH, estrogen, progesterone d. FSH, estrogen, LH, progesterone
Previously, birth control methods involving hormones were created only for females. However, a new form of hormonal contraceptive has been developed for males. The contraceptive involves a monthly injection of the hormone testosterone. Testosterone injections showed a 99% efficacy in preventing pregnancy. Which of the following rows correctly identifies the expected levels for the hormones involved in the production of sperm and the hormone that stimulates the production of testosterone in a male receiving testosterone injections, respectively? Select one: a. Sperm Production Testosterone Production Low FSH Low LH b. Sperm Production Testosterone Production Low LH Low FSH c. Sperm Production Testosterone Production High FSH High LH d. Sperm Production Testosterone Production High LH High FSH
Listed in the table below are the five major reproductive hormones that support ovulation in female mammals, including the giant panda. Describe the role of each hormone in this process and the approximate time during the ovarian cycle that it reaches peak levels. Hormone Gonadotropin-releasing hormone (GnRH) Estrogen Luteinizing hormone (LH) Follicle stimulating hormone (FSH) Progesterone Role in Regulation of the Menstrual Cycle Timing of Peak Level
Describe the role of progesterone in pregnancy including what produces it during pregnancy, its role in labor and delivery and how it effects at least two other body systems/tissues during pregnancy.
A non-pregnant female's uterus shed its lining (the outer endometrial layer) every 4 weeks and then begins the menstrual cycle anew, the cycle's timing being controlled by female reproductive hormones. A successful pregnancy requires that the menstrual cycle be interrupted and the fetus left undisturbed for 9 months. Cycle interruption is accomplished by the fetal placenta, which secretes several key hormones that manipulates maternal reproductive physiology. Give at least three (3) hormones that control the maternal reproductive physiology, give their specific functions/role.
Unlike male gonadotropins, female gonadotropins are able to promote the development of a single optimal dominant follicle during most cycles with the release of a single gamete from an LH surge and then optimization of the uterine environment for implantation. To understand pathologies in this complex system, one must understand the ideal steps within the normal menstrual cycle. Which of the following statements best describes the role of FSH in menstruation? O FSH induces granulosa cell LH receptors within the dominant follicle. O FSH stimulates follicular growth only in the early preantral stage. ( ) FSH stimulates granulosa cell androgen production. O FSH increases its own receptor numbers on theca cells. O FSH induces theca cell aromatase.
Both pituitary (FSH and LH) and ovarian (estrogen and progesterone) hormones are involved in regulating the menstrual cycle. Which of the following most accurately describes the order these hormones are released at their highest levels from day 1 to the end of a menstrual cycle if no pregnancy occurs? Select one: a. LH, FSH, estrogen, progesterone b. FSH, estrogen, progesterone, LH c. FSH, estrogen, LH, progesterone d. FSH, LH, estrogen, progesterone
Describe the development of reproductive organs in a fetus of each gender. Which genes, gene products, and hormones are involved in the sex differences? Which sex- related hormones are circulating in high concentrations in a pregnant woman compared to a nonpregnant woman? Do these hormones cross the placenta (if you are uncertain, consider hormone chemical class relative to membrane permeability to make an educated guess)? Assuming these hormones do cross the placenta, how do they affect the hormonal environment inside the fetus, and how does this relate to fetal reproductive development?
A patient presents requesting hormonal contraception . She has been researching her options on the Web and has become confused by the large variety of OC pills available , including monophasic, multiphasic , and progesterone only . She asks how the pill prevents pregnancy and why the variety of preparations . Which of the following is the primary mechanism by which OCs prevent pregnancy ? Increasing cervical mucus viscosity Inhibiting serum follicle stimulating hormone (FSH) levels Inducing lymphocytic endometritis Inhibiting serum luteinizing hormone (LH ) levels
Which of the following mechanisms best explains the contraceptive effect of birth control pills that contain both synthetic estrogen and progestin? Inhibition of ovulation Impairment of implantation hyperplastic changes of the endometrium Production of uterine secretions that are toxic to developing embryos Impairment of sperm transport due to uterotubal obstruction Direct inhibition of oocyte maturation
Conditions that cause the fallopian tubes to be narrower than normal may result in: Implantation of a fertilized ovum within the tube. More rapid propulsion of the ovum through the tube. Increased likelihood of pregnancy during each cycle. Excessive cramping and bleeding during menstruation .
