A multiple pregnancy from a single zygote is called monozygotic, from two zygotes is called dizygotic, or from three or more zygotes is called polyzygotic. Similarly, the siblings themselves from a multiple birth may be referred to as monozygotic if they are identical or as dizygotic (in cases of twins) or polyzygotic (for three or more ...

With the use of reproductive technology such as fertility drugs and in vitro fertilization (IVF) such births have become increasingly common. This list ...
If the placenta is shared by more than two twins (see multiple birth), these are monochorionic multiples. Monochorionic twins occur in 0.3% of all pregnancies. [ 1 ] Seventy-five percent of monozygotic twin pregnancies are monochorionic; the remaining 25% are dichorionic diamniotic . [ 2 ]
Pregnancy is the time during which one or more offspring develops inside a woman's uterus (womb). [4] [13] A multiple pregnancy involves more than one offspring, such as with twins.

A heterotopic pregnancy is a complication of pregnancy in which both extrauterine pregnancy and intrauterine pregnancy occur simultaneously.

Teenage pregnancy, also known as adolescent pregnancy, is pregnancy in a female under the age of 20. [5] Worldwide, pregnancy complications are the leading cause of death for women and girls 15 to 19 years old.

The step lengthens as the pregnancy progresses, due to weight gain and changes in posture. On average, a woman's foot can grow by a half size or more during pregnancy. In addition, the increased body weight of pregnancy, fluid retention, and weight gain lowers the arches of the foot, further adding to the foot's length and width.
