Ovulation is normally suspended during pregnancy to prevent further ova becoming fertilized and to help increase the chances of a full-term pregnancy. However, if an ovum is atypically released after the female was already impregnated when previously ovulating, a chance of a second pregnancy occurs, albeit at a different stage of development.

A variety of hormones can be tested at different times in the menstrual cycle to determine the likelihood of different responses to stimulation for In vitro fertilization (IVF). Pregnancy rates in ovulation induction when using antiestrogens, as functions of the size of the leading follicle as measured by transvaginal ultrasonography at days 11 ...
Twins and triplets are sufficiently common to have their own separate articles. With the use of reproductive technology such as fertility drugs and in vitro fertilization (IVF) such births have become increasingly common. This list contains only multiple births which have some claim to notability, such as being the first recorded in a country ...
