I didn't want my blog to become stale but lately I haven't been writing much. I blame myself and Facebook and Instagram and Netflix and a few other life distractions. I am sure in the pre-social media years I got a lot more done. Then again, maybe I didn't and I am just glamourizing the olden days. Anyway, I am on vacation this week so thought I'd put fingers to my keyboard.
I'm in Hawaii with my family and in-laws (a lot of in-laws) so this seems like a pretty good time to slip away for "me time." During this "me time" I've been reading a few journal articles. After all there is only so much social media you can consume before you feel terrible about yourself and the world. When I read journal articles I feel better about myself, my practice and the world. One article caught my eye tonight. It was a Swedish study looking at what factors predict whether you are going to get pregnant with IVF. It caught my eye as it was a big study - examining 8400 IVF/ICSI cycles. Such large studies usually can be relied on to make sound conclusions. Well, it was anti-climatic as the list is quite predictable: young age, lots of eggs, few/no prevous failed IVF cycles, endometrial thickness (> 7mm is good) etc. Interestingly though, a new variable they found that correlated with IVF success was female height (not BMI). Being taller was associated with a higher success rate. Why? Their thoughts were: "Human height has steadily increased over the past centuries, which has been interpreted as a consequence of improvements of health and nutrition. It could be speculated that growth factors involved in procreation might also be involved in body growth."
Historically we have thought of the "fertile body type" as voluptuous, round, full but maybe the tall thin women is more appropriate. I'm a fairly tall person. One of my daughters said to me today "your body is a lot like Uncle John's." So maybe she was telling me I had a really fertile body type, as my brother in-law, John, is tall and thin. Probably not though and my self-image took another hit.
