Abstract
The aim of the present study was to perform laparoscopic inoculation of frozen semen and to determine the fertility rate after laparoscopic inoculation into one or both uterine horns regardless of the ovulation site in Afshari ewes.

The studied animals included 11533 Afshari ewes (age range 2-6 years) with an average weight of 57.3 ± 4.1 kg and the body condition score (BCS) of 3.1 ± 0.1.

The highest fertility was observed in spring and summer compared to autumn and winter (p
