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
