22 Year Record For Sperm Storage And Pregnancy
A British guy suffering from leukemia had his sperm stored 22 years ago and his sperm produced a baby 22 years later - a new record.
Chris Biblis was 16 when doctors told him that he needed radiotherapy that would leave him sterile and recommended before going ahead with the life-saving treatment that they put a sample of his sperm into cryogenic storage for future use.
Now aged 38, he is celebrating the birth of a healthy baby daughter, Stella, who was conceived after scientists injected a defrosted sperm into an egg from his wife, Melodie, and implanted it in her uterus.
I'm thinking guys in their teens ought to get their sperm stored and girls in their teens ought to get their eggs stored.
Women wouldn't need to undergo heavy (and risky) hormone therapy to extract eggs. A technique called in vitro maturation (IVM) cuts costs and risks with IVM down to $5000 at one clinic. What I wonder: can eggs be frozen before maturation? That'd delay costs and make egg storage at a young age more affordable.
Huge banks of stored sperm and eggs would open up the possibility of much bigger and higher quality markets for sperm and eggs. Once DNA sequencing becomes cheap I expect teens will advertise for offers for their sperm and eggs by publishing their DNA sequences on web sites under pseudonyms.
But when do you think it will be possible to synthesize a complete human being from scratch in a laboratory?
If I understood some recent articles, a virus has already been manufactured from scratch.
How many girls in their teens have $5000 to burn?
And, I've got to say, if today you were a teen aged girl who took that advice, and spent the money your parents gave you for your first car on egg storage... Thirty years from now you'll really be kicking yourself when doctors can take a scraping off your cheek, run it through error correction to sort out the mutations, install the latest genetic upgrades, and deliver a lifetime supply of better eggs the next day.
I seriously considered cord blood storage when our 6 month old was born. And rejected it, on the basis that we were remarkably unlikely to need it before creating stem cells from ordinary body cells was routine medicine. (And on the basis that we were nearly broke, too, of course.)
I thought I've seen ads for selling eggs in college papers. So, if you sold some and kept the rest on ice for yourself, mightn't that even out?
Need to unriddle the reason why IVF kids have poorer overall health than the non-IVF kind before this should really be widely adopted.
Bbartlog, where'd you read that?
Are IVF-conceived children taller?
31 July 2007
"The study (by Harriet M L, et al, 2007) compared 69 IVF-conceived children in the age group of 4-10 years that formed the “Study group” to 71 normally conceived children that acted as the control. The selection and comparison criteria included factors such as socio-economic status, age of the child, race, sex, nutritional status and also height of their parents’.
"When the results were analysed, IVF-conceived children comparatively showed some promising positive signs. The most noticeable result was their height which was 3 cm higher on an average. These children were also slimmer than those in the control group with better blood lipids which regulate fat.
"The researchers of the study have put forth factors such as genetic variation and selection of better quality embryos for embryo transfer that may be responsible for the above findings.
It can be argued that it is too early to jump to conclusions that all babies conceived following IVF are taller. The study did not included IVF children from frozen embryo transfer and only singleton pregnancies were considered for this study."
