Progestin Provera (2012-01-15)

Why not just use the progestin Provera as prescribed by most doctors?

If you have just about any doubts about how various progesterone is from the progestins, keep in mind that the placenta produces 300-400 milligrams of progesterone daily over the past few months of pregnancy, so we know that such levels are safe for the creating baby.

But progestins, perhaps at fractions with this dose, can cause delivery defects. The progestins additionally cause many other side effects, including partial loss of vision, breast cancer throughout test dogs, an increased risk of strokes, liquid retention, migraine headaches, asthma attack, cardiac irregularities along with depression.

Scientists record electrical currents that give sperm boost to finish line

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. 
Biologists Yuriy Kirichok and Polina Lishko of the University of California at San Francisco, 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 has 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.

Graduating from Clomid - An overview of infertility medications

Prescirbed medications include:

GnRH Agonists (leuprolide acetate, Lupron) and GnRH Antagonists, (Ganirelx Acetate or Cetrotide).

GnRH agonists and antagonists work by suppressing a woman’s natural hormone production to prevent ovulation from occurring prematurely and are given by subcutaneous injection.

Gonadotropins, Follicle Stimulating Hormone (FSH): Bravelle, Follistim, Gonal-F; Follicle Stimulating Hormone & Lutenizing Hormone (FSH&LH): Menopur, Repronex; Lutenizing Hormone: Luveris; hCG: Novarel, Profasi, Ovidrel).

These medications stimulate the ovaries to develop and mature follicles and ultimately eggs. They are usually give subcutaneously but may also be given intramuscularly. Although these medications must be prepared a bit differently prior to administration, the actual injections are the same.

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.

JJ hospital to study contraceptive for new momsMUMBAI: JJ Hospital in Byculla is among the 20 centres in the country where the much-awaited research on progesterone vaginal ring (PVR), a form of contraception mainly for breast-feeding women, kicked off this week. 
The study, initiated by the Indian Council of Medical Research ( ICMR), is aimed at assessing the acceptability and efficacy of this hormonal contraception among Indian women. The ring, which is made of soft and flexible material, is to be placed in the vagina for continuous use and replaced every three months.
