gestaní

Gestaní is a term used in several Slavic languages to denote the period of gestation, the time during which an embryo or fetus develops in the uterus. In English, the closest equivalent is gestation or pregnancy. The word generally appears in medical and veterinary contexts to describe prenatal development and the duration of the carrying of offspring.

In human medicine, gestation is often described in terms of gestational age, which is usually counted from the first day of the last menstrual period. The typical duration is about 38 to 42 weeks, with an average of around 40 weeks (about 280 days). This framework helps clinicians assess fetal development and plan prenatal care.

Development during gestaní is commonly divided into two main periods. The embryonic period lasts roughly the first eight weeks after fertilization (or up to about ten weeks gestational age), during which the major organs and body structures begin to form. The fetal period extends from the ninth week of gestation until birth, when organs mature and grow to support postnatal life. The placenta and umbilical cord play essential roles in nutrient supply and waste removal throughout the gestational process.

Variations in gestaní length occur across species; within humans, deviations from the typical range are linked to risks. Preterm birth is defined as delivery before 37 weeks of gestation, while post-term birth occurs after about 42 weeks. Factors influencing duration include maternal health, fetal development, and obstetric conditions.

The term’s usage varies by language and region, and in English-language medical literature the English equivalent gestation is more common, while gestaní may appear in local clinical vocabularies.
