Reproductive Flashcards

1
Q
  • Occurs in young men usually between 20-40 years of age
  • Is highly curable
  • 90% of newly diagnosed respond to treatment
A

Testicular Cancer

  • Characterized by tumor cell markers (hCG, LDH and AFP).
  • Most testicular tumors are germ cell tumors that arise from the spermatozoa (seminoma) or other germline tissue (non-seminoma).
  • Seminomas tend to retain the features of the spermatozoa, whereas the non-seminomas contain multiple cell types and are less differentiated than seminomas.
  • Non-germinal cell tumors arise from seminiferous epithelium.

Q
  • Common endocrine disorder affecting 5-10% of women of reproductive age
  • Characterized by high androgen levels associated with acne, hirsutism, and insulin resistance leading to hyperinsulinemia
  • Conditions that are often associated, such as obesity, T2DM, hyperlipidemia
  • Anovulation, amenorrhea, infertility
A

Polycystic Ovary Syndrome (PCOS)

  • Diagnosis involves clinical presentation combined with a number of tests for hormone levels, in particular androgens (male hormones) including testosterone, with free testosterone levels elevated in ~60% of PCOS patients.
  • Treatment is guided by patient goals but include lowering of insulin, restoration of fertility, treatment of hirsutism or acne, and restoration of normal menstruation to prevent endometrial hyperplasia and endometrial cancer.
  • PCOS is a complex, heterogeneous disorder of uncertain etiology, but evidence suggests a genetic component to the disorder, perhaps in an autosomal dominant manner with high penetrance but variable expression.

Q

Process of Lactation

A
  • Prolactin and estrogen develop breast tissue during pregnancy

  • Acrosomal reaction: contents of acrosome released
    • ​occurs BEFORE fertilization
  • Block to polyspermy: enzymes released to prevent additional sperm from binding
    • ​occurs AFTER fertilization
  • Completion of meiosis II (oocyte)
  • Fusion of pronuclei of ovum and spermatozoa
