Sexual Development (10.1)

  • Sex retais at the gemenic or physiological characs of males or females
  • Gender refers to socially-influenced identity, role, and or behavior
  • Intersex - describes variety of combos of biologically male and fern. characs. such as indiv.  born with external female genitalia internal male sex organs
  • Production of Gametes fertilization
  • All cells, except sperm / ova, contain 23 chrom. pairs, which contains the gene info of DNA
  • Gamete (mature reproductive cell; sperm / ovum) production entails a special form of cell division called meiosis - produce cells that contain one set of ea. of the pairs of chromosomes.
  • A person’s genetic sex - determined by presence of XX (fem) or XY (male) chroms, determined at time of fertilization of ovum by the father's sperm
  • 22 of 23 chrom. pairs determine org's physical development + indep of its sex; the last pair consists of two sex chroms (x,y)
  • Developemnt of Sex organs
  • Exposure to se mormones both before after birth, is responsible for sexual dimorphism: y chromosomes control development of male sex hormone glands
  • Gonads - ovary or testis; First to develop
  • Have a dual fxn- produce ova/sperms secrete hormones
  • Thru the 6th week of prenatal development, males female fetuses are identical; both sexes have pair of identical undifferentiated gonads, which have potential of developing into either testes or ovaries
  • The factor that controls their development appears to be a single gene on the Y chromosome called SRY - gene on Y chromosome whose product instructs the undiffer. Fetal gonads to develop into testes
  • SRY gene begins the process of gonadal diff., but two other genes are necessary for completion
  • Sex determining region Y
  • If SRY not present, the gonads become ovaries
  • Once gonads have developed, another series of events occur, which are directed by hormones
  • During prenatal development, these hormones have organiz. Effect (on tissue diff. and development); effect are permanent and persist throughout person’s life
  • Hormones also have activational effects - hormone effect that occurs in fully developed organs, depends on organs prior exposure to the organizational effect of hormones
  • Occurs after sex organs have developed,
  • Internal sex organs (ISO)
  • Early in embryonic development, the ISOs are bisexual - all embryos cointain in the precursors for both female and male sex organs
  • During 3rd month of gestation, only one precursor develops
  • Mullerian system - embryonic precursors of female ISO; develops into fimbriae and fallopian tubes, uterus, inner ⅔ of vagina
  • Wolffian system - embryonic precursors of male ISO; developes into epididymis, vas deferens, seminal vesicles
  • ISO development of fetus determined by presence or absence of hormones secreted by testes - if these hormones are present, the wolffian system develops; if not, then mullerian does
  • Mullerian needs no additional hormonal stimulus from the gonads to develop; in contrast, wolffian cells don't develop unless they are stimulated to do so by a hormone
  • Testes secrete two types of hormones
  • Anti-mullerian hormone - peptide secreted by the fetal testes that inhibits mullerian development; has a defeminizing effect chromone effect that reduces or prevents later development of anatomical or behavioral female characteristics
