Embryo loss

Embryo loss (also known as embryo death or embryo resorption) is the death of an embryo at any stage of its development which in humans, is between the second and eighth week of gestation.[1] Failed development of an embryo often results in the disintegration and assimilation of its tissue in the uterus. Loss during the early stages of prenatal development of the fetus results in the similar process of fetal resorption.[2] Embryo loss often happens without an awareness of pregnancy, and up to 70% of all embryos do not survive.[3]

Fertility clinics

Within fertility clinics embryo loss is associated with a high number of implanted embryos.[4] The keeping of embryos in tanks can also increase risks of loss in instances where technical malfunctions can occur.[5]

gollark: Also, it has versions.
gollark: I suspect your foreword thing might actually be incompatible with that.
gollark: Then you would need to explicitly release it under some free software license. Which yours might not be.
gollark: Actually, the way it works is that if you program something/make some sort of creative work, you own the "intellectual property rights" or whatever to it (there's a time limit but it constantly gets extended), and have to explicitly release it as public domain/under whatever conditions for it to, well, be public domain/that.
gollark: ... it's saying what you can do with the (copyrighted) code.
