Twenty-six 75-day-old, ovariectomized Long-Evans female rats were randomly divided into two groups of ten and one group of six animals. The ten Group I Ss received, in consecutive treatment periods, 2 mg progesterone (P-2) daily, 2 mg testosterone propiorate (TP-2) daily, TP-2 daily plus P-2 every fourth day, and P-2 every fourth day. The ten Group II Ss received, in consecutive treatment periods, P-2 every fourth day, and 4 mg dihydrotestosterone (DHT-4) daily plus P-2 every fourth day. Both...

The ten Group I Ss received, in consecutive treatment periods, 2 mg progesterone (P-2) daily, 2 mg testosterone propiorate (TP-2) daily, TP-2 daily plus P-2 every fourth day, and P-2 every fourth day. The ten Group II Ss received, in consecutive treatment periods, P-2 every fourth day, and 4 mg dihydrotestosterone (DHT-4) daily plus P-2 every fourth day. Both Groups I and II were tested for female sexual behavior. A significant increase in the lordosis response was observed only in Group I Ss after receiving TP-2 plus P-2 every fourth day. Group III Ss were tested for male sexual behavior after receiving DHT-4 daily. Male sexual behavior increased significantly after DHT-4 treatments. It was concluded that progesterone exerts a facilitatory effect on female sexual behavior only when the Ss have been previously primed with an aromatizable androgen and that dihydrotestosterone is capable of inducing male sexual behavior in female rats.

Fourteen 75-day-old female rats of the Long-Evans strain were ovariectomized and divided into two groups of seven. Group I received daily injections of 2mg testosterone propionate (TP) and was tested for male sexual behavior. Group II, in addition to daily injections of TP, also received injections of 1mg progesterone on five of the ten test days. This group was tested for female sexual behavior. TP was found to exert a facilitory effect on both male and female sexual behavior. Female sexual...
Show moreFourteen 75-day-old female rats of the Long-Evans strain were ovariectomized and divided into two groups of seven. Group I received daily injections of 2mg testosterone propionate (TP) and was tested for male sexual behavior. Group II, in addition to daily injections of TP, also received injections of 1mg progesterone on five of the ten test days. This group was tested for female sexual behavior. TP was found to exert a facilitory effect on both male and female sexual behavior. Female sexual behavior was enhanced further when progesterone was administered 4 to 6 hours prior to testing. Progesterone, when injected alone, was found to induce lordosis. It was concluded that TP was first being converted to estrogen and it was the estrogen which was responsible for the increase in female sexual behavior. The fact that progesterone, which enhances estrogen-induced lordosis, also enhances testosterone-induced lordosis supports this position.

- THE EFFECT OF DORSAL HIPPOCAMPAL LESIONS ON THE SEXUAL BEHAVIOR OF THE MALE RAT.
- Creator
- MILLS, JEANNE THERESA, Florida Atlantic University
- Abstract/Description
-
Performance on three preoperative and three postoperative copulation tests was compared for male rats given dorsal hippocampal, dorsal hippocampal plus cortical, other lesion, and sham lesions. Dorsal hippocampal lesions produced statistically significant changes in the temporal pacing of some components of sexual behavior, i.e. the post-ejaculatory interval, intercopulatory interval, and total test time decreased. Hippocampal plus cortical lesions had no effect on sexual behavior. The...
Show morePerformance on three preoperative and three postoperative copulation tests was compared for male rats given dorsal hippocampal, dorsal hippocampal plus cortical, other lesion, and sham lesions. Dorsal hippocampal lesions produced statistically significant changes in the temporal pacing of some components of sexual behavior, i.e. the post-ejaculatory interval, intercopulatory interval, and total test time decreased. Hippocampal plus cortical lesions had no effect on sexual behavior. The results are interpreted as supporting a model of inhibition in which a sexual inhibitory process is built up concomitantly with the sexual arousal process.

- THE EFFECT OF SEXUAL BEHAVIOR ON HYPOTHALAMIC BIOGENIC AMINE CONCENTRATION IN THE INTACT MALE RAT.

- Abstract/Description

The present study investigated the role of brain serotonin activity in the mediation of masculine sexual behavior in the intact male rat. The results of previous studies suggest a dissociation of the effects of gonadal hormones on central serotonin metabolism and sexual behavior in the male rat. However, serotonin activity was measured some 24 hours after the last test of sexual activity. In the present experiment, animals were assigned to one of five groups, and were sacrificed by...
Show moreThe present study investigated the role of brain serotonin activity in the mediation of masculine sexual behavior in the intact male rat. The results of previous studies suggest a dissociation of the effects of gonadal hormones on central serotonin metabolism and sexual behavior in the male rat. However, serotonin activity was measured some 24 hours after the last test of sexual activity. In the present experiment, animals were assigned to one of five groups, and were sacrificed by decapitation immediately after meeting their respective behavioral criterion. High performance liquid chromatography (HPLC) was used to measure concentrations of serotonin and its metabolite, 5-hydroxyindoleacetic acid, in the hypothalamus-preoptic area. Analyses of variance revealed no significant differences in brain serotonin activity as a function of sexual behavior. Results are discussed in the context of the role of biogenic amines in the mediation of masculine sexual behavior in the male rat.

Forty-eight adult Long-Evans male rats were tested following castration for male and female sex behavior. Following baseline test Ss received 200 mug injections of estradiol daily except on days of female tests when 20 mug of progesterone were given. Tests for male and female behavior were alternated every third day. Significant increases in mean lordosis and male behavior occurred following hormone treatment. After hormone tests eight Ss received anterior lesions and five Ss received...
Show moreForty-eight adult Long-Evans male rats were tested following castration for male and female sex behavior. Following baseline test Ss received 200 mug injections of estradiol daily except on days of female tests when 20 mug of progesterone were given. Tests for male and female behavior were alternated every third day. Significant increases in mean lordosis and male behavior occurred following hormone treatment. After hormone tests eight Ss received anterior lesions and five Ss received preoptic lesions. Afer recovery Ss were placed on the same schedule of hormones and tests as for the previous condition. No significant changes in mean lordosis or male behavior occurred following either lesion. It was concluded that estrogen is effective in restoring male behavior and producing female sex behavior in castrated males. While no significant changes occurred following the lesions, it was determined that repetition and extension of the work is justified.
