This is a picture of a human fetus at 20 weeks' gestational age (i.e. 18 weeks after fertilization). A colour version of this image is available at Wikimedia See larger version at 3D Pregnancy. A rotatable 3D version of this photo is available here, and a sketch is available here.& martin is gonna be the BEST daddy ever The company behind is Tribal Internet Projects, a Dutch-based publisher of family websites. was launched in 2007.

This particular picture was drawn by Melchior Meijer who is a 3D artist. He and used various resources to produce the illustration, including books, DVD's and websites to verify how a fetus looks at this stage of development. Some of the resources relied upon were as follows:

A Child is Born (A book by Lennart Nilsson)

Other sources for assessment of accuracy

When comparing this image to other images, it should be kept in mind that this stage of development is often referenced using different numerical descriptions. This is an approximate drawing of a fetus 18 weeks after fertilization, i.e. at the beginning of the 19th week after fertilization. This is equivalent to a gestational age of about 20 weeks, i.e. at the beginning of the 21st week of gestational age. This drawing can be compared to other online images of a fetus at approximately the same stage of development, including the following images:

(1) Photograph of fetus during 18th week after fertilization, from Thomas W. Sadler, Langman's Medical Embryology, page 92 (2006) via Google Books;
(2) Motion-picture 4D ultrasound of fetus at 19 weeks after fertilization, from the Endowment for Human Development;
(3) Drawing of fetus at 20 weeks’ gestational age, from which has a medical review board;
(4) Drawing of fetus at 20 weeks' gestational age, from Michigan Department of Community Health.
Note that during week 11 of gestational age, the eyelids fuse and remain fused until week 24. See Michele Isaacs Gliksman, The Complete Idiot's Guide to Pregnancy and Childbirth, p. 113 (2004).

Details about donation of image

The owners of this image donated it to Wikimedia. The original version that the owners donated had a watermark which has subsequently been removed according to Wikimedia policy. See here. The present image (without watermark) was donated by Wouter Vergeer on Wednesday, August 29, 2007 on behalf of Mr. Vergeer stated in an email to Ferrylodge on that date:

For now we are only willing to share these four 3D pictures under the CC-SY-BA license. Lets first see how this goes before we decide to share more or, perhaps in the future, all our works....I noticed you changed the picture and removed the CC-SY-BA notification. Which is fine by us. We just added them to make sure everybody saw they were released under CC-SY-BA license and nobody would delete them. We did notice, however that the quality of the images has decreased

quite a lot due to the cropping. I enclosed new versions of the images at better quality with this email. Would you be so kind to upload these? Or should we do this? The company behind is Tribal Internet Projects. We are Dutch based publisher of family websites. We are working on a corporate website containing more company information. If you have any more questions, please let me know. And thank you for your involvement. With kind regards / Met vriendelijke groet,
