His delivery broke the world record for the oldest known human embryo to result in a live birth. The achievement has been officially recognized by Guinness World Records because his embryo was frozen seven months before those of the previous record holders. Timothy and Lydia Ridgeway, of Vancouver, Washington, will celebrate their third birthday at the end of this month. They were conceived in April 1992 and their embryos were kept in storage for 29 years and 9 months before being transferred.
A breakthrough was announced last week in the world of fertility science. Scientists took skin cells from a human and used them to make egg cells. Yes, you read that right: skin made an egg. They then fertilised the egg with sperm by IVF and took it to the stage where it could be implanted into a womb.
If she can afford it, tell the LW to freeze her eggs! We have one amazing daughter, but haven't been able to have any more children (just two miscarriages, three egg retrievals with only one healthy embryo, and then a failed embryo transfer). Egg quality decreases with age and starts to drop quickly after 40-if she can bank some eggs now, she can buy herself some time for family-building and take the pressure off of meeting someone immediately. Wishing her luck.
I spent the long months of pregnancy that followed feeling like a cartoon character with a me-size thunderstorm threatening at every turn. Though my pregnancy was healthy, I was convinced I had to remain vigilant until my son was in my arms. When my husband and I visited my obstetrician nine days past my son's due date, I wasn't surprised to see an irregularity in his heartbeat. Less than an hour later, we were checking into the hospital to start my induction.
With IVF, prospective parents already have options to screen embryos, not just for sex or severe genetic diseases, but increasingly for a full range of genetic traits. Thanks to whole genome sequencing (WGS), the choice isn't science fiction; we can now analyze all 20,000+ human genes in an embryo with better than 99.9 percent accuracy for many mutations and chromosomal problems (assuming parents are willing to forego natural conception, and instead supply their eggs and sperm to a lab for embryo creation and analysis).
Women who want to to get pregnant should refrain from using cannabis. This is the conclusion of a new study that examined the influence of the substance, and its active ingredient THC in particular, on female fertility and artificial insemination. Researchers found that cannabis can negatively affect both because it disrupts the development and stability of the egg cell. During in vitro fertilization (IVF), egg and sperm cells are brought together in a laboratory.
The debate centers on whether to unwind Colorado's sperm donor regulations, concerned that they have deterred donations for aspiring parents while emphasizing the need for oversight.
