umm i just wanna ask, wen my periods are getting close, i get pimples. wen its over, it goes away. why?

[Dr.Stein]

Pimples, acnes is a sign of excessive androgen level In female, most androgen will be converted into estrogen by aromatase. This estrogen is about to reach peak when is closed to our periods.

are pimples genetically inherited?

hey what abt

the question on visible symptoms during estrus of animals
if there r any

The Estrus Cycle

Canine: Bitch
Puberty occurs at 6 months of age. They generally cycle every 6 months (Variable with breed/size)
A. Proestrus: Increased follicular activity in the ovaries.
Physical signs: Vulva will swell, vaginal bleeding.
Vaginal Cytology: RBC’s, WBC’s & parabasal epithelial cells
Lasts: 7-10 days
B. Estrus: “Standing Heat”. Most receptive and most fertile at this time. This is the period just prior to ovulation.
Physical signs: Lack of bloody discharge- becomes clear
Vaginal Cytology: Few cells, clear background
Lasts: 3-5 days
C. Metestrus/Diestrus: Period that immediately follows ovulation. CL is producing progesterone. Not fertile a this time.
Vaginal Cytology: Many WBC’s, fewer epithelial cells
Lasts: 80-90 days
*If the dog does not become pregnant, the CL will diminish.
* Pseudocyesis: False Pregnancy. When the CL does not completely diminish. These dogs will look and act pregnant, some will go through a nesting phase, false labour, and depression when no pups are produced.
D. Anestrus: Most variable period of activity in the dog. Hormone levels are low, animals is non-receptive and exhibits no signs of sexual behaviours.
Physical signs: Small and dry vulva, small mammary glands.
Vaginal Cytology: Large numbers of epithelial cells.
Lasts: 100-135 days
* FSH activity increases after this phase, and the cycle begins again.




Feline: Queen. Reach puberty at 7-12 months of age.
* Induced Ovulators: Need coitus to ovulate. If a cat goes into season, they will stay in until bred. If a male cat is not present, the cycle lasts ten days longer.
1) Proestrus: Increased activity, rubs against objects and rolls freuquently
2) Estrus: Crouch with tail und up in the air. Tail moves from side to side and she will accept the male.

Equine: Mare. Reach puberty at 10-24mos of age (generally 18mos)
*Polyestrus: Several estrus cycles per year. Their natural breeding season is from May through August.
1) Estrus cycle: Approx. 21 days
2) Standing Heat: Estrus- lasts 5 days
3) Veterinarian can predict ovulation based on visual exam and palpation
4) Vaginal cytology not performed because changes are not distinctive enough to determine stage of cycle.

Bovine: Cow
* Polyestrus.
1) Cycle lasts 21 days
2) Estrus Lasts: 18 hours
3) Signs: nervousness, vocal, attempt to mount other animals, thick and clear mucous discharge from vulva.
4) Bleeding occurs at the end of estrus- going into metestrus. At this stage it is too late to breed the cow.




Those are just a few species....

are pimples genetically inherited?

Could be yes, could be not

[jnkdna]

so ur answer is.........'maybe'?
well my pimples have sort of cleared. at least my skin is better know than wen i was 11yrs old!!

[Dr.Stein]

No no, not "maybe". I said "could be" because acnes or pimples can be caused (1) genetically, means the over expression of androgen-regulatory related gene, and this is inherited, or (2) individual body metabolism, or (3) life-style, means that this is individual and not inherited, e.g. diet, environment, hygiene, etc.

[jnkdna]

oh well my diet aint that bad. i take a shower everyday so hygiene aint a problem. environment is dry, im not sure if theres a connection. and my dad had it in his teens so i figured i inherited it.

[Dr.Stein]

You miss one thing: your metabolism?

[jnkdna]

how do i know how my metabolism works?

[Dr.Stein]

Do physiological processes, e.g. check your oxygen consumption, heartbeat frequency, hormone biosynthesis, urine analysis, blood pressure, liver function, IgG level...
