Mittelschmerz is one-sided, lower abdominal pain that occurs in women at or around the time of an egg is released from the ovaries (ovulation).
Ovulation pain; Midcycle pain
Causes, incidence, and risk factors
About 20% of women experience mittelschmerz, or pain associated with ovulation. The pain may occur just before, during, or after ovulation.
There are several explanations for the cause of this pain. Just prior to ovulation, follicle growth may stretch the surface of the ovary, causing pain. At the time of ovulation, fluid or blood is released from the ruptured egg follicle and may cause irritation of the abdominal lining. Mittelschmerz may be felt on one side one month, then switch to the opposite side the next month, or it may be felt on the same side for several months in succession.
The pain is not harmful and does not signify the presence of disease. In fact, women who feel this pain may be at an advantage ...
Last week Zogenix, Inc., a pharmaceutical company that develops products for treating central nervous system disorders and pain, announced positive results from its pivotal Phase 3 efficacy study of Zohydro (hydrocodone bitartrate) extended-release capsules. Hydrocodone is an opioid pain reliever used to treat moderate to severe pain. Currently in the U.S., hydrocodone is only available in immediate-release form and is always combined with acetaminophen.

If Zohydro receives FDA approval, it could achieve two firsts:
The first extended-release hydrocodone treatment, which is better for the treatment of chronic round-the-clock pain. (It would provide 12-hour pain relief rather than the 4 t...
In order to understand how pregnancies occur in the first place, you'll need to learn a little about your menstrual cycle, hormones and ovulation (release of the egg). As you'll see, it's not very complicated. What is a Menstrual Cycle? Simply put, it's the preparation a woman's body makes for pregnancy every month. It's called a cycle because the same hormonal and physical events occur in sequence each time to prepare an egg for fertilization. The average length of a menstrual cycle is 28 days; however, it can be up to a week shorter or longer and still be normal. Let's take a closer look at menstrual cycles: When a girl reaches about the age of 12, her body has already gone through many changes internally and externally. Menstrual cycles are a final step in puberty and signal the beginning of her ability to bear children. Her brain, ovaries and uterus have established a working relationship to produce an egg each month and a place for it to grow, if it...
