Infertility in a male Caucasian dog treated with Clomid and vitamins

Abstract

A two-year-old Caucasian male dog weighing 55.4 kg was presented to the Veterinary Teaching Hospital with the complaint of infertility. History evaluation revealed that he had mated ten bitches in the last eight months impregnating none of them. Clinical examination, laboratory investigations and semen evaluation were performed twice, 60 days apart. Semen and sperm parameters were poor with low percentage motility and vitality, low concentration, and high percentage of sperm abnormalities. No significant bacteria were isolated from cultures of the semen and preputial swab. Scrotal ultrasonography showed no evidence of testicular degeneration. Pre-treatment serum hormonal evaluation showed normal concentrations of follicle-stimulating hormone (FSH), luteinising hormone (LH), testosterone, thyroxin (T4), triiodothyronine (T3), prolactin and resting cortisol as well as low bicarbonate level. Haematology revealed evidence of leucocytosis. Based on the history, clinical examination and laboratory findings, the case was diagnosed as idiopathic oligoasthenoteratozoospermia (OAT). Here, a possible management of idiopathic OAT in a Caucasian dog with oral Clomiphene citrate (Clomid®) together with Vitamins E, C and B supplements for 60 days is described. Altogether, there was a marked improvement in the semen and sperm parameters at 90 days from the onset of treatment. Semen volume increased, together with increased sperm motility, vitality and concentration, and decreased percentage of sperm with morphological abnormalities.
