How does estrogen in contraception pills prevent fertilisation in the first place?

How does estrogen in contraception pills prevent fertilisation in the first place?

Works in pituitary: The estrogen in the pill alters the normal feedback to the pituitary gland, which in turn prevents the changes (rise) in fsh (follicle stimulating hormone) and lh (luteinizing hormone) levels which lead to ovulation, which is the release of the egg from the ovary. Since the egg doesn't leave the ovary, it is not physically accessible for the sperm to fertilize it. ...Read more

Can hormones in Mirena (levonorgestrel) cause the linea nigra?

Can hormones in Mirena (levonorgestrel) cause the linea nigra?

Unusual: It's more common with combination hormones, especially with the higher dose pills, and of course in pregnancy. I've not seen it with Mirena (levonorgestrel) since the amount of systemic hormone (amount in your body's circulation) is very small. Make sure you're not pregnant and check with your Doc if you notice more darkening pigmentation. Take care. ...Read more

When prometrium (micronized progesterone) stimulates instead of sedates a perimenopausal woman what should be taken? Estrogen in combo with prometrium (micronized progesterone)?

Go see your doctor: While our impression of estrogen for perimenopausal women has changed dramatically over the last decade, it still should be used for right reason, and sedation is not one of them. So go see your prescribing doctor & tell her/him about your side effects so that s/he can offer you some alternatives (rather than just throw more medications at you). ...Read more

Why is estrogen combined with progestogen in oral contraceptives?

Minimize spotting: Break-through-bleeding (btb) is common with the progestogen (p) only oral contraceptive pills (ocp).
