Gestation refers to the process of implantation and development of fertilized ovum

To confirm these results, the researchers used an experimental model to test the effect of keeping the Suv4-20h2 active in the fertilized ovum
Kobak et al (5) explained that the majority of intraligamentary pregnancies occur as a result of the rupture of tubal ectopic pregnancies along the mesosalpingeal border with secondary escape and implantation of the fertilized ovum

The pregnancy in a non-communicating horn is possible only through trans peritoneal migration of the sperm or fertilized ovum
