ABSTRACT The genitalia of male rat foetuses whose mother animals had been treated from the 16th to the 19th day of pregnancy with 6-chloro-/6-1,2α-methylene-17α-hydroxyprogesterone-acetate, a synthetic steroid with high progestational effect, were underdeveloped. The changes are irreversible.

Heavy Training

Overtraining syndrome is a decrease in physical capacity, emotions and immunity due to training that is too often without adequate periods of rest. Overtraining is often experienced by athletes who daily undergo heavy training with short break periods. This research aims to look at the effect of overtraining aerobic physical exercise on memory in mice. The research method was experimental in vivo with the subject of adult male rat (Rattus Norvegicus) Winstar strain aged 8-10 weeks, body weight 200-250 gr. Divided into three groups, namely the control group, aerobic group and overtraining group. The results of memory tests with water E Maze showed an increase in the duration of travel time and the number of animal errors made by the overtraining group (p = 0.003). This study concludes that overtraining aerobic physical exercise can reduce memory in rat hippocampus.

Androgenic Effect

ABSTRACT Experiments are described dealing with the mechanism of action of 6-chloro-Δ6-1,2α-methylene-17α-hydroxyprogesterone-acetate with regard to its anti-masculine effect on male rat foetuses, when administered to pregnant rats. It was shown that a marked direct anti-androgenic effect due to a competitive action on androgen receptors within the target organs, is probably the explanation of the mechanism of action. It was further shown that an oestrogenic effect or an appreciable inhibition of the pituitary gland respectively, can be ruled out as causative factors in the mechanism of action.
