Question
Chapter 16, Problem 5CT
Summary Introduction
To speculate: The reason why tumors of the pituitary or adrenals might disrupt monthly menstruations.
Introduction: The female reproductive system consists of reproductive organs both internal and external that are involved in reproduction and propagation of the species. The diseases and disorders of the organs of the female reproductive system show several systems. The absence of menstrual flow where the female misses three menstrual periods in a row or delay in onset of menarche row is called as amenorrhea.

Mumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face. However, the virus can also infiltrate the male reproductive system, causing the testes to atrophy. Some effects include oligospermia (low sperm count), azoospermia (no sperm in semen), and asthenospermia (reduced sperm movement).
Research treatment options for reduced sperm movement. Describe one option that can be used to aid successful fertilization and explain why it helps.
Clomiphene Citrate is a fertility drug that stimulates hypothalamic secretion of Gonadotropin releasing Hormone (GnRH) in females and induces ovulation. Explain how increased GnRH with Clomiphene Citrate treatment would affect follicle maturation and ovulation in women (explain how increased GnRH would affect FSH, LH, Estrogen, and ovulation).
Chlamydia is caused by the bacteria Chlamydia trachomatis. If not treated, it can cause pelvic inflammatory disease (PID) in women and epididymitis in men. PID can cause scar tissues in the structure responsible for transporting the fertilized egg and in the tissue that is maintained by progesterone during a menstrual cycle, leading to infertility.
In the diagram above, the structures associated with PID for the effects described above are numbered

- At the midpoint of the menstrual cycle, estrogen promotes a sudden surge of LH from the pituitary. What would be the consequence of an endocrine disrupting chemical (EDC) in the environment that mimics estrogen and is present throughout the cycle? Group of answer choices pituitary hyperplasia (cell growth) cancer development uterine contractions ovulation would not occur cervical dilationarrow_forwardUnlike 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.arrow_forwardMumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face.
