reproductive system

FUNCTION (male reproductive system): produce and deliver sperm to the female reproductive organs while secreting male hormones into the body

FUNCTION (female reproductive system): produce/ deliver eggs to site of fertilization in which the fetus will be developed and nurtured until time of delivery while also producing female hormones into the body

HORMONES USED

male: testosterone

  • Develop and maintain secondary sexual
    characteristics
  • Sperm cell production

Female:

  • Progesterone: triggers uterine changes during the menstrual cycle
  • Estrogens: responsible for female secondary sexual characteristics,
  • Androgens: produce some changes at puberty

Methods of contraceptives

Rhythm Method: abstinence sexual
intercourse around ovulation

Coitus Interruptus: withdrawal of penis before ejaculation;

Mechanical Barriers: prevent sperm from entering vagina

Chemical Barriers: contain spermicides

Combined Hormone Contraceptives: contain estrogen and
progestins- disrupt normal hormonal
patterns of female cycle (prevent follicle maturation/ ovulation)

Contraceptive Implants: implantation of a rod containing
progestin under the skin in the arm

Intrauterine Devices (IUDs): implanted in uterus- toxic to sperm / egg cells / prevent implantation
embryo (inhibiting growth endometrium)

Sterilization: surgical methods of permanently preventing
pregnancy

Male (vasectomy): remove portion
vas deferens preventing sperm from entering semen

Female (tubal ligation): cut uterine tubes preventing
sperm from reaching egg

Events of the female hormonal cycles

menstratinal cycle

(1) anterior pituitary gland secretes FSH/ LH

reproductive anatomy

reproductive anatomy

2 testis (scrotum)

2 epididymis (scrotum around tesis)

2 ductus vas deferens (travel up around urinary bladder to ejaculatory duct)

2 seminal glands (superior ejaulatory duct)

3 ejaculatory duct (near prostate)

prostate (inferior to urinary bladder)

urethra (run from both bladder/ ejaculatory duct to external urethral orifice)

penis corpus (full penis superior to scrotum)

glans penis (tip of penis)

bulbourethral gland/ duct (inferior to prostate along urethra)

external urethral orifice (end of urethra)

fundus of uterus (top of uterus)

2 uterine tubes (top of uterus both sides)

2 infundibulum (end of uterine tube)

2 fimbriae (holds onto ovary)

2 ovary (ends of fimbriae)

body of uterus (superior to vagina) layers: 1st- Perimetrium/ 2nd- Myometrium/ 3rd- Endometrium

lumen ( uterus cavity)

cervix (uterus opening)

vagina ( inferior to cervix tunnel)

2 labium minus (small flap to vagina opening)

2 labium majus (larger flap to vagina opening)

(2) FSH stims maturation dominant follicle

(3) Follicular cells produce/ secrete estrogens (Estrogens maintain secondary sex characteristics/ endometrium to thicken.

before puberty

(4) anterior pituitary releases surge LH = ovulation

(5) Follicular cells = corpus luteum cells (secrete estrogens/ progesterone) - E = uterine wall development/ P = endometrium glandular/
vascular / both = secretion FSH/ LH -
anterior pituitary gland.

(6)If secondary oocyte not fertilized corpus luteum
degenerates/ no longer secretes estrogens/ progesterone

(7) estrogens/ progesterone decline/ blood
vessels in endometrium constrict

(8) uterine lining disintegrates/ shed = menstrual flow

(9)The anterior pituitary gland is no longer inhibited = secretes
FSH/ LH

(10) cycle repeats

(1) Oogonia give rise to oocytes (Before birth) oogonia multiply - mitosis (development fetus) oogonia begin meiosis stop in prophase I = primary oocytes (remain until puberty)

(2) (Before birth) primary oocytes surrounded - single layer of granulosa cell = primordial follicle (present until puberty)

(3) (After puberty) primordial follicles = primary follicles
when granulosa cells enlarge/ + number

(4) fluid-filled vesicles develop/ theca cells arise on the outside of the follicle = Secondary follicles

(5) vesicles create a single antrum = Mature follicles

(6) (before ovulation) primary oocyte completes meiosis I
= secondary oocyte/ nonviable polar body

(7) secondary oocyte begin meiosis II (stop at metaphase
II)

(8)(During ovulation) secondary oocyte is released -
ovary

(9) The secondary oocyte completes meiosis II (if fertilized)
completion of meiosis II = oocyte/ second polar body

  • Fertilization is complete when the oocyte
    nucleus/ sperm cell nucleus unite = zygote

(10) (Following ovulation) granulosa cells divide rapidly/
enlarge = corpus luteum

(11) corpus luteum degenerates = scar/ corpus
albicans

syphilis: infection that can cause serious health problems without treatment

transmission: sore contact/mother>child/vaginal/oral/anal

signs: sores(mouth/genitalia/anus)/fever/may have none

treatment: antibiotic (may not undo damage)

prevention: avoid sexual contact/ single partner

transmission: anal/vaginal/oral sex wo protection

signs: none/mild/ blisters(mouth/genitalia/anus)/flu symptoms

treatment: none/antiviral meds/ medication(prevent outbreak)

prevention: protection/ avoid sexual contact

chlamydia: can cause permanent damage to women if not treated

transmission: unprotected sexual contact/ anal/oral/vaginal
