Lisääntymistermi

Lisääntymistermi is a Finnish term that translates to "reproductive term" or "gestational term" in English. It refers to the duration of pregnancy in humans and other mammals. The length of a lisääntymistermi can vary significantly depending on the species. In humans, the typical lisääntymistermi is considered to be around 40 weeks, or 280 days, calculated from the first day of the woman's last menstrual period. This period is often divided into three trimesters, each of approximately 13 weeks.

The precise calculation of the lisääntymistermi is important for monitoring the progress of a pregnancy, assessing fetal development, and determining the estimated date of delivery. Medical professionals use this term to schedule prenatal check-ups, screenings, and to identify potential risks or complications. While 40 weeks is considered full-term, pregnancies can be considered healthy if they fall within a certain range, typically between 37 and 42 weeks. Pregnancies ending before 37 weeks are classified as premature, and those extending beyond 42 weeks are considered post-term. Understanding the lisääntymistermi is fundamental to prenatal care and managing the journey of pregnancy.
