amid restrictions related to the spread of coronavirus, in the past few years there has been a decrease in the number of procedures such as IVF (extrakorporporeal fertilization).

In a study published in the journal “Human Reproduction” of Oxford University, data on the indicators of twins pregnancy in 2010-2015 out of 165 countries are collected. These figures were compared with data for 1980-1985.
