Women Need Progesterone (1/14/2012)

Why do women need to have progesterone?

Women Need Progesterone

Progesterone is needed in hormone replacement therapy for menopausal ladies for many reasons, but one of its most important roles is to balance as well as oppose the effects associated with estrogen. Unopposed estrogen produces a strong risk for breast cancer and reproductive : cancers.

Estrogen levels fall only 40-60% at the change of life, which is just enough to stop the menstrual cycle. However progesterone levels may decrease to near absolutely no in some women. Due to the fact progesterone is the precursor to be able to so many other anabolic steroid hormones, its utilize can greatly increase overall hormone stability after menopause. Progesterone additionally stimulates bone-building and thus helps protect against osteoporosis.

When the stork makes a delivery, Thomas Jefferson University Hospital wants to ensure he doesn’t arrive too early. Starting in 2012, the hospital’s department of obstetrics will recommend a simple test to all pregnant women in its care midway through their pregnancy. It will measure the length of their cervix using an ultrasound. “We have been doing it for certain high-risk pregnancies. What’s new (is) we’ll do it for all pregnant women,” said Dr. Jason Baxter of Haddonfield, a perinatologist and director of research for Jefferson’s department of obstetrics and gynecology in Philadelphia.

Performance anxiety? Not for this human sperm. He doesn't know the bright lights and cameras are for him. He doesn't know he's swimming on a glass stage with no egg. And he's clueless that researchers are watching his every move at high magnification -- viewing his inner workings. UC San Francisco biologists Yuriy Kirichok and Polina Lishko have made a name for themselves recording the electrical currents that course through, yes, sperm cells. Their work is not only offering new hope to infertile couples, but also may lead one day to an effective male birth control pill. 

In a pivotal study, the husband-and-wife team have uncovered how progesterone -- a hormone involved in menstruation and embryo development -- switches on a sperm's internal electricity. The electric current kicks sperm tails into overdrive, powering the final push toward the egg. Sperm that fail to heed progesterone's "get-up-and-go" signal could help explain some couples' struggles to conceive, say Kirichok and Lishko, both Ukrainian immigrants. The pair also studies mito
