Icosuplets are 20 offspring at once for humans.
No, it is not possible. It is possible. But it would be the rarest rare could ever get. It would be very rare.
Icosuplets, or a set of 20 children born from a single pregnancy, are extremely rare. The chances of a natural conception resulting in icosuplets are virtually impossible due to the limitations of the human body and the risks involved in carrying and delivering such a large number of babies. In most cases, multiple births of this magnitude are the result of fertility treatments such as in vitro fertilization, which significantly increases the likelihood of multiple embryos implanting in the uterus.
I believe it is possible, you could have more than twenty babies [icosuplets] at once. It is not very likely but it could happen.
quintuplets, then sextuplets, septuplets, octuplets, nonuplets, decaplets, undecaplets, duodecaplets, tredecaplets, quattrodecaplets and quindecaplets. I don't know any more! quintuplets sextuplets septuplets octuplets nonuplets decaplets undecaplets duodecaplets tredecaplets quattrodecaplets quindecaplets sexdecuplets septdecuplets octdecuplets nondecuplets icosuplets
21 at a time would be unicosuplets. 22 at a time would be duoicosuplets. 23 at a time would be tresicosuplets. 24 at a time would be quattroicosuplets. 25 at a time would be quinticosuplets. 26 at a time would be sexicosuplets. 27 at a time would be sepicosuplets. 28 at a time would be octicosuplets. 29 at a time would be nonicosuplets.
