Slang Definition. Words that are not a part of standard vocabulary or language and are used informally are called slang. These words are mostly used in speech rather than in writing. Slang can be divided into four different types; country slang, urban slang, gay slang and common slang.
The exact timing will depend on the age of the embryos at transfer. If you have frozen the embryos at day two, transfer will happen two days after ovulation. If you have frozen the embryos at day five, transfer will happen five days after ovulation, and so on. The idea is to mimic the natural process as closely as possible.
The embryos were then transferred to recipient women. They had pregnancies when the recipient's cycle was from 4 days in front of to 3 days behind the donor's uterus at ovulation. This suggests a window of implantation of up to 7 days. Navot et al, in 1991 reported on donor embryo transfers done with 2-3 day old embryos on recipient cycle days 15-20 (artificial cycles controlled with meds).
