Hernandez Linsi The Reproductive System
period; 1
Major functions of the Reproductive system Male
The males function of the reproductive system is to...
To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen)
To discharge sperm within the female reproductive tract during sex
To produce and secrete male sex hormones responsible for maintaining the male reproductive system
Major functions of the Reproductive system Female
The major function of the reproductive system of the female is to
produce female gametes and to secrete female sex hormones, estrogen and progesterone
It is more complex because of pregnancy
Anatomy of male reproductive structures
The males reproductive system include
Primary sex organ; gonads (Testes)
Gamete; sperm
sex hormones; Testoosterone
Anatomy of female reproductive structures
The females reproductive system include
Ovaries
Gametes; ova
Sex hormones Estrogens & Progestrone
What are the names of the types of hormones in the male reproductive system?
There are two types of hormones in the male reproductive system called
Testosterone
,
Steroid
,
follicle stimulating hormone (FSH), & luteinizing hormone (LH)
What are the names of the types of hormones in the female reproductive system?
There are names of the types of hormones in the female reproductive system are called
estrogens, progesterone, gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and leutenizing hormone (LH)
Events of the female hormonal cycles
Ovarian cycle is a 28 day series of events;
F
ollicular phase (1-14)
During this phase follicles become sensitive to FSH & are stimulated to grow.
Ovulation;
It occurs in between Follicular & luteal phase. The egg bursts from its follicle and expels secondary oocyte
Luteal phase (14-28
) After ovulation occurs, the ruptured follicle collapses & antrum fills with clotted blood. Sometimes pregnancy wont occur, so the corpus luteum degenerates within 10 days. However, if pregnancy does occur, corpus lute produces hormones that sustain pregnancy until placenta takes over.
What are some disorders associated with the reproductive system?
Some disorders of the reproductive system are called
clamydia, trichomoniasis, gonorrhea, and syphilis
Describe the disorders associated with the reproductive system
-Chlamydia
is the most common bacterial STI in the United States and can be contracted from birth canal by new borns
-Trichomoniasis
is a parasitic infection that is more common in women than in men. It is also easily inexpensively treate
-Gonorrhea
is a bacterial infection of mucosal of reproductive and urinary tracts. Males & females have different symptoms when it comes to this disease, male; can include urethral contraction & inflammation of duct system & In female; abdominal discomfort, vaginal discharge, or abnormal uterine bleeding
-Syphilis
is a bacterial infection transmitted sexually or congrnitally
HIV
How many layers does the uterus include?
There are three walls;
Perimetrium
; outermost serous layer
Myometrium;
Bulky middle layer consisting of interlacing layers of smooth muscle
Endometrium;
mucosal linining
What are the stages of the menstrual cycle?
Menstrual phase (1-5)
:** Ovarian hormones are at their lowest levels. Gonadotropin levels then begin to rise.
The proliferative phase (6-14):
Rising estrogen levels prompt generation of new stratum functionalist layer.ThenEstrogen also increases synthesis of progesterone receptors in endometrium and ovulation occurs at end of proliferative phase on day14
Secretory Phase (15-28);
Endometrium prepares for embryo to implant. If the fertilization does not occur the corpus luteum degenerates toward end of secretory phase. Then progesterone levels fall endometrial cells die, and glands regress and functional layer sloughs off and uterine cycle starts all over again.
What are 3 key differences between oogenesis & spermatogenesis
1; production of primary oocytes occurs only in fetus
2; In primary oocytes, meosos, is arrested in late prophase I & resumes only years later
3; In secondary oocytes meiosis is arrested in metaphase II & 15 inly completed if fertilization occurs
What is the difference between the female & male reproductive system?
The difference between them is that the male reproductive system consists of external organs mean while the female reproductive system consists of internal organs
Describe the hormonal regulation of the ovarian cycle?
1;
GnRH
stimulates FSH & LH secreation
2;
FSH & LH
stimulate follicles to grow, mature & secrete sex hormones
3; Negative feedback inhibits gonadotropin release
4; Positive feedback stimulates gonadotrpin release
5;
LH
surge triggers ovulation & formation of the corpus lutem
6; Negative feedback inhibits
LH & FSH
release
Describe the ovaries of the female.
Produces the egg (gland that produces estrogen and progesterone)
What are the main male organs in the reproductive system?
The main male organs in the reproductive system are the
penis, scrotum, testes, epididymis, vas deferens, prostate, and seminal vesicles.
