Metformin May Not Be The Best Anti-Diabetic For Getting Pregnant Naturally With PCOS

Hello all you wonderful people viewing this through your computer screen or mobile device!

I apologize for my lack of recent postings, I will be coming back with a vengeance don’t you worry! Lots of new topics up my virtual sleeve πŸ™‚

I was doing some research and I had to share this with you. I came across an article on Google News: Pregnancy rate doubles with exenatide vs. metformin in PCOS.

Here are the main findings of the article:

‘The rate of natural pregnancy was higher following exenatide therapy vs. metformin (43.6% vs. 18.7%), according to researchers. Menstrual cycle also became more regular in both groups, with greater improvement observed in those assigned exenatide (P <Β .001). The most frequent adverse events reported were mild or moderate gastrointestinal discomfort.

The fact that subjects lost more weight with EXE may partly explain why the participants in the EXE group had more regular menstrual cycles than those in the MET group.’

This is one of the first times that I have heard of exenatide therapy. Or at least of ‘exenatide therapy’ in the broad sense. I wanted to share a little about what the treatments Metformin and Exenatide therapy are. Exenatide therapy is similar to Metformin in that it works to improve glycemic control, and therefore, combat insulin resistance. While Metformin is an oral anti-diabetic (known as a Biguanide) that works to decrease the production of glucose in the liver, Exenatide therapy (often marketed under the tradenames Bydureon, Victoza, or Byetta) is administered as a weekly injection. These types of drugs are called GLP-1 receptor agonists (agonist just means something that causes a response in the body when it is combined with a receptor (receptor is usually a site where a protein, hormone, or neurotransmitter can sit to activate a response elsewhere in the body)), which mimic the effect of glucagonlike peptide- 1, a hormone that increases insulin production when blood sugar is high (Sorry guys, I’m a science nerd and I love human physiology. Don’t hold it against me). So in essence, the drug mimics this hormone (called GLP-1) and causes the body to produce more insulin (increased satiety -feeling full- was also reported).

Fun fact, exenatide itself is a hormone that is derived from the Gila Monster. If you don’t know what this is it’s a big ass lizard found in the Southwest US and Mexico. Kind of weird, kind of cool, kind of gross. I have mixed feelings….I’ve included a few pictures of the Gila Monster below for your viewing pleasure.

 

It’s eyes are staring into your soul……
