title: [Quantifiable morphokinesis on parts of the hypothalamo-adenohypophyseal-gonadal axis of hormonally castrated boars. I. Studies on boars treated with chlormadinone acetate].
abstract: A clearly morphokinetic effect was recorded from the parts of the hypothalamo-adenohypophyseo-gonadal axis in boars that had been treated with chloromadinone acetate (CAP). Luteinising hormone release is inhibited by CAP, which is reflected in an increase of luteinising hormone cells in their storage form. This leads to statistically significant decline in androgenic testicular tissue percentage and in the cell nucleus volumes of Leydig's cells. Excessive weight decrease of the testicle is caused primarily by some 60 per cent reduction in tube length. The neurons of the tested hypothalamic nuclear region, that is the nucleus praeopticus medialis, have shown that in treated animals cell nucleus volumes were significantly depressed.
