ABSTRACT

 

AL-Sariy SM, ALwan SH,  Habeeb IA, Hassan AM., Effect of unilateral and bilateral ovariectomy on blood progesterone, estradiol and fertility in  dogs, Onl J Vet Res., 23 (12):1191-1194, 2019.  We report effect of unilateral versus bilateral ovariectomy on blood progesterone and estradiol in sixteen 1-1.5 year old 15-20kg stray dogs at surgery and 30 days later. Groups of 4 dogs each were subjected to unilateral left or right or bilateral ovariectomies. Controls (n=4) were normal dogs. Blood was taken before (Day 0) surgery and 30 days later for sex hormones measured by radioimmunoassay. Compared with controls in dogs with bilateral ovariectomy progesterone declined 94% by day 30 (P < 0.01) but there was no significant change  (P > 0.05)(~-66%) in estradiol values. In dogs with left or right ovariectomy, estradiol declined ~8% (P < 0.01) with again no change (P > 0.05) in progesterone. Results suggest that removal of one ovary in dogs maintains normal sex hormone levels by 30 days.

 

Keywords: Ovariectomy, unilateral, bilateral, progesterone, estradiol.
