Reproductive System Flashcards
Menstrual cycle consists of two stages
Ovulation and mensuration
Endometrium
Lining of the uterus
Ovulation
Process which the ovarian follicles ruptures and releases the egg
Condition causes males to not produce enough testosterone
Hypogonadism
Alpha adrenergic blockers do what to urinary flow
Relax smooth muscles in bladder neck and prostate there by increasing urinary flow
Peripheral zone of prostate is more effected by
Carcinoma
Central zone of the prostate are prone to
Hyperplasia
Life cycle of sperm
70-75 days
Stimulates production of testosterone
Hormone LH
Causes sperm production
Hormone FSH
Testies produce
Sperm and androgens
Prostate gland
Situated at base of bladder and around the urethra, also secrets prostate solution that ejaculates with sperm that helps increase chances of fertilization
Poly cystic ovarian syndrome (PCOS)
6% of women, increased androgen production producing high LH and low FSH. Preventing maturation of egg, inflammation and edema occur in Fallopian tube, hempering passage of matured egg creating a cyst
% of infertility in men women and both
35, 35, 20, 10% no cause can be found
During breast feeding dopamine a prolactin inhibitory factor causes
Milk to no longer be produced or secreted
During breastfeeding oxytocin enables
Milk secretion by expanding and contracting milk ducts
During pregnancy prolactin causes
Milk production
Female hypogonadism
Inadequate production of estrogen in ovaries. Symptoms may be lack of mensural cycle, breast development, stunted growth.
Spermicide foam is most effective spermicide and working in 2 ways
- Forming physical barrier of the cervix
2. Immobilizing and killing sperm
Active ingredient in spermicide and its purpose
Nonoxynol - 9
Reported to cause lining of vaginal wall to thin or erode faster
Can reduce effects of birth control
Antibiotics, anti fungal, anti epileptic

Hytrin
Tamsulosin
Flomax
Uroxaral
Alfuzosin
Cardura
Doxazosin
Avodart
Dutasteride
Parlodel
Bromocriptine
Levitra
Verdenafil
Cialis
Tadalafil

Sildenafil
Progesterone “mini pills” are only _____% effective
93%
MOA of progesterone only BCP
Prevents fertilization by preventing full egg development, thickening cervical muscles, slowing down flagellation (sperm tail movement) preventing sperm from entering uterus
Progesterone only pills are called
Mini pills or POPs
MOA of hormone contraceptive
To maintain high level of hormones in blood preventing release of FSH by imitating levels of pregnancy
Second form of BCP would be post fertilization, the MOA is
To change uterin lining to block implantation of embryo
MOA of prefertilization BCP
- Prevention of ovulation
2. Thickening of cervical muscle to act as barrier to sperm reducing chances
End of a mensural cycle means that hormone levels will reduce, what happens when a woman becomes pregnant
Progesterone & estrogen continue. The follicle that became a corpus lutem produces hormones as endicore system till the placenta takes over about 2 to 3 months after implanting
What does the follicle turn into after ovulation
Into a corpus luteum with help of LH, producing estrogen and progesterone
Ovulation is ________, and takes about ______ days
Where the egg travels Fallopian tube, about 5 days
Around day 14 in cycle high % of LH cause
Follicle to rupture releasing mature egg
Reproductive cycle last about
28 days
Progesterone during pregnancy
Maintains uterine lining
Progesterone means
Hormone for life
Progesterone promotes development of
Endometrium (uterine lining) and mammary duct
Estriol is formed by
Metabolized estradiol and estrone
Estrone is most prominent in women
Post menopausal
Estradiol is most prominent in women
Premenopausal
Estrogens are the “feminizing” hormone because
They create higher voice, breast development, curvaceous body shape, less bulky muscle
Estradiol function is to
Stimulate development of uterine lining & mammary gland to ready body for pregnancy
Egg develops in _____ days in the overly
11-17
During mensural cycle hormone FSH triggers
Follicles to develop and release of mature egg
Females are born with about _____ eggs, by puberty have about ____ eggs remaining
2 million, 400,000
BPH effects
Prostate gland
STD / STI
Gonerria ( bacteria). Herpes (virus)
Coloymydia (bacteria). Lice / crabs (parasite)
Bacteria vaginitis. Molluscum (virus)
Genital warts. Syphillis (bacteria)
HIV & AIDS (virus). Trichomonas (parasite)
Vaginal yeast (fungal)
Main female issues with their reproductive system
- Menopause - hormone imbalance
2. Hypogonadism - decrease in hormones being produced
Benign Prostatic Hyperolasia (BPH)
Inflamed prostate gland - non cancerous
Main male issues with their reproductive system
- Testosterone deficiency
- Eric the disfunction (ED)
- BPH - benign prostatic hyperplasia
Issues with an IUD
Can go into uterus, PID - pelvic inflammatory disease
Forms of birth control
- Condoms - latex 99% effective
- lamb - not as effective and does not perfect against STD - Pill
3 diaphragm - lates or silicone barrier
4 spermicide - sponge, cream, gel - IUD - with or without hormone
Male sex hormones
High testosterone / low estrogen
Estrogens most prominent to least prominent in women
Estradiol - most common
Estrone - most common after menopause
Estriol - weakest
GnRH
Gonodotropin releasing hormone

Clitorus
Female internal sex organs
2 ovaries
2 Filopian tubes
Uterus
