31 sie 2022 · We present a case of monozygotic (identical) triplets who have each transitioned from female to male under the care of a university transgender health service. Each triplet experienced gender dysphoria from childhood and has undergone transitional endocrine care and various aspects of gender-affirming surgery.
Monozygotic triplet pregnancies are very rare, even after in vitro fertilization (IVF). We present a case of a live birth of triplets from a monochorionic triamniotic pregnancy after blastocyst transfer. A 29-year-old woman underwent intracytoplasmic sperm injection (IVF-ICSI).
1 sty 2020 · Zygosity is the term that describes the number of zygotes from which a multiple pregnancy is produced. In the simplest form, twins may either be monozygotic (i.e., produced from a single zygote) or polyzygotic, namely, dizygotic, trizygotic, etc. (i.e., produced from two, three or more zygotes).
Zygosity refers to the genetic makeup of the pregnancy, or the number of zygotes that become fertilized leading to a multiple birth. Twins, in rarer cases triplets, quadruplets (four), quintuplets (five), arising from a single fertilized ovum are termed monozygotic (MZ).
13 sty 2021 · Looking at 381 monozygotic twin pairs and 2 triplets, the authors first estimated the number of postzygotic mutations present in one twin but not the other.
