Unreferenced text on safety
The following piece of text was found in IVF. However, since equivalent reports are already given in this article, I think this text needs a more specific link to the original study to justify insertion. Mikael Häggström (talk) 07:54, 8 June 2011 (UTC)


 * It seems the text refers to this study:


 * I added some results of it. Still, feel free to complement if you find anything important missing from it. Still, let's try to keep it short and simple. Mikael Häggström (talk) 08:22, 8 June 2011 (UTC)

Alternative to abortion?
Is it possible to use this as an alternative to aborting an unwanted embryo or are the timescales incompatible. i.e you don;t find out your pregnant until after the timepoint where you would need to remove the embryo for preservation.131.251.252.33 (talk) 19:41, 15 October 2013 (UTC)

the history section is confusing. Did Trounson & Mohr discover embryo cryopreservation, or was it Subash Mukhopadyay?
History The first ever pregnancy derived from a frozen human embryo was reported by Alan Trounson & Linda Mohr in 1983 (although the fetus aborted spontaneously at ten weeks of gestation); the first term pregnancy derived from a frozen embryo was born in 1984.[15] Since then and up to 2008 it is estimated that between 350,000 and half a million IVF babies have been born from embryos frozen at a controlled rate and then stored in liquid nitrogen; additionally a few hundred births have been born from vitrified oocytes but firm figures are hard to come by. It may be noted that Subash Mukhopadyay, from Kolkata, India reported the successful cryopreservation of an eight cell embryo, storing it for 53 days, thawing and replacing it into the mother’s womb, resulting in a successful and live birth as early as 1978- a full five years before Trounson and Mohr had done so. A small publication of Mukherjee in 1978 clearly shows that Mukherjee was on the right line of thinking much before anyone else had demonstrated the successful outcome of a pregnancy following the transfer of a 8-cell frozen-thawed embryo into human subjects transferring 8-cell cryopreserved embryos." (Current Science, Vol .72. No. 7, 10 April 1997)

Perhaps the section should be rewritten along the lines. Credit for the first ever pregnancy is usually given to Alan Trounson & Linda Mohr in 1983...but some historians believe the first case was carried out by Subash Mukhopadyay, from India....
