Q

Luteinizing hormoon LH

A

Wanneer er in een piekniveau is binnen de menstruele cyclus, zal binnen 24-48 uur het follikel openbarsten en het eitje vrijkomen

29
Q

Estrogen

A

Predominant in first half of menstrual cycle

30
Q

Progesterone

A

Predominant in second half cycle and early pregnancy

31
Q

Prolactin

A

Stimulates production of milk by the mammary glands

32
Q

Oxytocin

A

Stimulates contractions of the uterus during childbirth, promotes ejection of milk from nipples and promotes affection

33
Q

Estrogen and progesterone are important
- ovaries produced

A
  • Estrogen brings about many of the changes of puberty, maintains the mucous membranes of the vagina, and stops the growth of bone and muscle in females
  • Levels of estrogen and progesterne fluctuate according to the phases of the menstrual cycle, pregnancy and menopause
    –> FSH and LH in the female regulate the levels of estrogen and progesterone; and inhibit FSH production
34
Q

Prolactin and oxytocin
- pituitary produced

A
  • Prolactin stimulates production of milk after a birth
  • Oxytocin stimulates ejection of milk from the nipples, stimulates contractions of the uterus during childbirth and promotes affectionate bonding
  • Note oxytocin is produced in both males and females
  • Levels of estradiol and progesterone do not differ between adult men and women; only testosterone levels differ, with men having more
35
Q

Fluctuations in sex drive for women

A
  • Some found a peak frequency of intercourse around ovulatio
  • otehers found peaks just before and just after menstruation
  • one study indicated that sexual activity initiated by the woman peaked during the three days before and three days after ovulation
36
Q

Cycles in men

A

Traditional assumption is that men do not experience monthly cycles
- men’s testosterone levels displayed weekly fluctuations
- men with a female partner and who wished to have a child dipsplayed a 28-day cycle of testosterone levels
- men who had sex with an unfamiliar partner showed a 100 percent increase in testosterone levels the following morning

37
Q

Sex chromosomes

A

Specific sec chromosomes carried in a fertilized egg are the deciding factor in whether it will become a male or a female (XX = female; XY = male)
- in the 7th week after conception, basic structures have formed. Sex chromosomes direct various organs to begin differentiation

38
Q

Klinefelter’s syndroom

A

XXY –> de man heeft kleine testikels, er wordt geen sperma geproducerd en testosteronwaarden zijn laag+

39
Q

Gonads

A

In males the undifferentiated gonads develop into testes at 7 weeks. In females they develop into ovaries at 13-14 weeks
- on the Y chromosome, SRY, causes manufacture of testis-determining factor (TDF), and male development occurs
- SRY: sex determining region, Y chromosome

40
Q

Müllerian ducts

A

In females turn into the fallopian tubes, the uterus and the upper part of the vagina
- Tubercle becomes the cliteris, the flods become the inner lips and the swelling develops into the outer lips

41
Q

Wolffian ducts

A

In males supported by testosterone, turn into the epididymis, the vas deferens and the ejaculatory duct
- Tubercle becomes the glans penis, the folds form the shaft of the penis, and the swelling develops into the scrotum

42
Q

Descent of the testes and ovaries

A
  • Ovaries and tested are not from Mullerian or Wolffian origin
  • Ovaries and testes change shape and position as developmental changes take place
  • Ovaries travel from higher intra-abdominally to pelvis
  • Testes travels from near the top of the abdominal cavity down into the scrotum via the inguinal canal –> cryptorchidism (undescended testes)
43
Q

Brain differentiation

A

During the prenatal period, sex hormones act on the brain
- if testosterone is present during fetal development, estrogen receptors in the hypothalamus become insensitive to estrogen
- if estrogen is present, they ebcome highly sensitive to levels of estrogen in the bloodstream
Plasticity of the brain: constant changes in response to experiences

44
Q

Epigenetics

A

A funtional change to DNA that does not alter the genetic code itself, but leads to changes in gene expression
- Prenatal sexual differentiation of the brain may involve epigenetic factors that can lead genes to be expressed or silenced
- just a few brain structures show gender differentiation
- neuroscientists emphasize the plasticity of the brain, which is constantly changing in response to experience

45
Q

Atypische prenatale genderdifferentiatie

A
  1. Chromosomaal gender : XX, XY
  2. Gonaal gender: testes, ovaries
  3. prenataal hormonaal gender (testosteron in mannen) en prenatale en neonatale hersendifferentiatie (testosteron bij masculinisatie)
  4. interne organen
  5. extern genitaal uiterlijk
  6. pubertaal hormonaal gender
  7. toegewezen gender
  8. genderidentiteit
46
Q

Congenital adrenal hyperplasia CAH

A

Bij een genetische vrouw ontwikkelen de eierstokken zich normaal en wordt er een overschot aan androgenen geproduceerd.
- lijken op man, maar is vrouw

47
Q

Androgen-insensitivity syndrome AIS

A

Een genetische man produceert normale testosteronniveaus, maar het weefsel is hier ongevoelig voor, waardoor prenatale ontwikkeling gefeminizeerd wordt. De genitaliën lijken op die van een man

48
Q

Puberty

A

The time during which there is a sudden enlargement and maturation of the gonads, other genitalia and secondary sex characteristics, leading to reproductive capacity

49
Q

Adolescence

A

A socially defined period that bears some relationship to puberty
- psychological transition from the behavior and attitudes of a child to the behavior, attitudes and responsibilities of an adult
- does not exist in some cultures

50
Q

Puberty in girls

A

Includes: breast dvelopment, growth of pubic hair and increased body growth
- Estrogen eventually stops the growth spurts in grls, sooner than in boys, accounting for women’s lesser average height
- first menstruation 12-13 years of age (leptine en kisspeptine)

51
Q

Leptine

A

Is gerelateerd aan de start van de puberteit en lichaamsvet. Een meisje gaat pas menstrueren als ze een bepaald percentage lichaamsvet heeft

52
Q

Kisspeptine

A

Stimuleert de hypothalamus om meer GnRH aan te maken, waardoor LH en FSH gestimulerd worden en de eierstokken oestrogeen gaan aanmaken

53
Q

Puberty in boys

A
  • growth of testes scrotal sac
  • growh of pubic hair
  • penis enlarges
  • growth of facial and auxiliary hair
  • erections increase in frequency
  • voice drops or changes
  • increased body growth
54
Q

Menstrual cycle

A

Menstrual cycle is regualted by fluctuating levels of sex hormones, which produce certain changes in the ovaries and uterus
- humans are nearly unique among species in having a menstrual cycle
- other species of mammals has estrous cycle: heat

55
Q

4 phases of the menstrual cycle

A
  1. Follicular phase
  2. Ovulation
  3. Luteal phase
  4. Menstruation
56
Q

Pollicular phase
- proliferative

A

Just after menstruation, an egg matures in preparation for ovulation
- FSH is secreted to stimulate follicles in the ovaries
- One follicle begins to ripen and brings an egg to maturity
- Follicle secretes estrogen, stimulation growth of the endometrium

57
Q

Ovulation

A

Follicle ruptures, releasing the mature egg
- estrogen inhibits FSH production and stimulates the hypothalamus to produce GnRH, which causes the pituitary to begin production of LH

58
Q

Luteal phase
- secretory

A

After releasing an egg, the follicle turns into a glandular mass of cells called the corpus luteum, which manufactures progesterone
- Corpus luteum continues to produce estrogen and progesterone for 10-12 days
- If pregnancy does not occur, the hormone output declines sharply and the uterine lining is shed

59
Q

Menstruation

A

The endometrium of the uterus is sloughed off in the menstrual discharge

60
Q

Follicular phase - hormones

A

High levels of estrogen stimulate the endometrium

61
Q

Luteal phase - hormones

A

Progesterone secreted by the corpus luteum stimulate the glands of the endometrium to start secreting nourishing substances

62
Q

What happens in the uterus during menstrual cycle

A
  • Corpus luteum produces estrogen and progesterone for about 10-12 days
  • If pregnancy has not occured, hormone output declines
  • menstrual fluid: blood from the endometrium, degenerated cells and mucus from the cervix and vagina
63
Q

Menstrual cycle: length and timing

A

Normal menstrual cycle is 20-36 days (avg. 28)
- starts on day 1 for 4-5 days
- follicular phase: 5-13
- ovulation phase: day 14
- luteal phase: 15 untill the end

64
Q

Mittelschmerz

A

Some women report that they can feel themselves ovulate in the form of cramping in the lower abdomen

65
Q

Anovulatory cycle

A

Menstruation may take place without ovulation

66
Q

Dysmenorrhea

A

Painful menstruation
–> prostaglandins is possible cause

67
Q

Endometriosis

A

The endometrium grows ina place other than te uterus

68
Q

Amenorrhea

A

Absence of menstruation
- Primary: when female has not menstruated by age 18
- Secondary: absence when she has had at least one period

69
Q

Premenstrual syndrome (PMS)

A

Severe physical and psychological symptomes, such as depression and irritability, occuring just before menstruation
- Premenstrual dysphoric disorder (PMDD)
- 3-5%, age 35-43
- majority do not eperience fluctuations in mood
