Human Embryo (7th week of pregnancy)

    Newer Older

    This photo of an opened oviduct with an ectopic pregnancy features a spectacularly well preserved 10-millimeter embryo. It is uncommon to see any embryo at all in an ectopic, and for one to be this well preserved (and undisturbed by the prosector's knife) is quite unusual.

    Even an embryo this tiny shows very distinct anatomic features, including tail, limb buds, heart (which actually protrudes from the chest), eye cups, cornea/lens, brain, and prominent segmentation into somites. The gestational sac is surrounded by a myriad of chorionic villi resembling elongate party balloons. This embryo is about five weeks old (or seven weeks in the biologically misleading but eminently practical dating system used in obstetrics).

    The photo was taken on Kodak Elite 200 slide film, with a Minolta X-370 camera and 100mm f/4 Rokkor bellows lens at near-full extension. The formalin-fixed specimen was immersed in tapwater and pinned to a tray lined with black velvet. The exposure was 1/4 second at f/8.

    This image found its way to Wikipedia and on 29 Nov 2006 was promoted to the status of Featured Picture. It was Wikipedia's Picture of the Day for March 21, 2007.

    More recently, I added an image of a nine-week embryo to my Photostream. What a difference two weeks makes!

    Going backwards in time, I have an image of a 4- to 5-week embryo, which I also found in a tubal pregnancy.

      Yes, thank you for posting this picture. I found out I had an ectopic pregnancy at about 5 weeks and am still going through it now through methotrexate treatment. Some might think it a bit destructive and morbid to look at this whilst going through it, but I think it helps me get through it by imagining what my little fella may have looked like.

      Right now, the only things growing faster than your baby's brain may be your tingly, achy breasts.
      Thanks

      Hi, Lisa. Yes, the presentation you describe is much more common. It is very rare to find a well-preserved embryo in a tube removed for an ectopic. Usually we see some early placental tissue and a lot of blood clot, and presumably the embryo degenerated much earlier.

      Thanks for sharing your story. I hope everything has gone well for you in the aftermath.

      The "eminently practical dating system used in obstetrics" has a major flaw: it assumes a woman's cycle is always 28 days. I remember trying to explain to the docs that I had conceived four weeks after LMP (I have a regular 40 day cycle) instead of the assumed two weeks and so development was two weeks younger than that given. Sadly, I had to terminate but it was only after I insisted upon an ultrasound that my knowledge was accepted because, of course, the U/S showed a size 2 weeks younger than the obstetric date. This was very important because it meant I could have the VA/D&C method that was initially refused me as being "too late" and so saving me from the horror of being induced.

      Have to ask, how many women died from ectopics before surgery to remove them was a viable option? You make it almost sound common to remove tubes.

      Oh, and I used this photo here: photographicdictionary.com/e/embryo

      Complaints experienced by many pregnant women into early pregnancy loss of appetite are so few foods that have nutrients to meet your nutritional needs and the fetus is often overlooked. It’s important to maintain appetite during pregnancy, if you leave you lose your appetite during pregnancy, maternal and fetal health would be threatened.
