About the CONTRACEPTIVE Patch Talking to your children about sex can be daunting.

In case you have questions about how to talk to your child about sex, consider consulting your physician. Lots of parents find this challenging to tackle, and a health care provider might offer some helpful perspective. What Is the Birth Control Patch? The contraceptive patch is a thin, beige, 1¾-inch square patch that sticks to the skin. It releases hormones through the skin into the bloodstream to prevent pregnancy.ContinueHow Will the Patch Work? The combination of the hormones progesterone and estrogen in the patch prevents ovulation . If an egg isn’t released, a female can’t have a baby because there’s nothing for the male’s sperm to fertilize. The hormones in the patch also thicken the cervical mucus . The cervix may be the section of the uterus that sits within the vagina and acts as the opening to the uterus.The next study, on November 21 published online, 2012 in the journal Molecular Cell, addresses this presssing issue. Firstly, all the genes that progesterone activates or represses in breasts cancers cells were identified. Then the researchers determined which DNA sequences recognise the progesterone receptor in the genome. They discovered that these represented just a little proportion of the possibilities, making them believe interaction with DNA had not been sufficient. It was necessary for the sequences which bind to the receptor to be incorporated into nucleosomes, which provide interaction sites also. ‘It appears that the structure of chromatin can be fundamental for identifying the activation or repression of genes. The researchers believe that the only way to create increasingly particular and effective cancer remedies is by studying the role of all the components that regulate gene expression and cell proliferation in response to hormones..
