These included the number of intromissions and ejaculations, number of intromissions needed for one ejaculation, the time elapsing until the first ejaculation, and the duration of the refractory and activity periods. The possible role of thyroid hormones in the Nitric Oxide NO -mediated response to sexual stimulation, and on prostaglandin E 1 PGE 1 and Sildenafil in the treatment of erectile dysfunction was investigated using the corpus cavernosum of the New Zealand rabbit animal model. Thyroxine treatment produced contraction proportionate to the concentrations of PGE 1 and Sildenafil; providing evidence that the erectogenic actions of both PGE 1 and Sildenafil are possible only in the presence of adequate thyroid hormone level. The testis changes were accompanied by similar, though less marked, increases in the wt and DNA content of epididymis and accessory organs. The purpose of this study was to assess sperm production in these enlarged testes and measure changes in sperm reserves in the epididymis. Testes and epididymides were obtained from control rats or rats given PTU from birth to day 25 designated "treated" at 90,, and days of age. Thus, in the treated rats, DSP, like testis wt, plateaued at day Epididymal sperm reserves were also increased in treated rats at all ages, but the correlation between DSP and epididymal sperm reserves was weak. Sperm motility and concentration in caudal epididymal fluid of adult males treated from birth to day 25 with PTU were normal. These males were fertile and sired litters in which pup wt and pup number were normal. Maximal sperm production is reached at days of age in treated rats compared to days in controlscoinciding with the attainment of final testicular size. This system represents the first experimental model in which such large increases in sperm production can be produced. The neonatal PTU treatment does not appear to impair fertility or alter sperm characteristics when these animals become adults and may be a useful system with which to study factors which normally regulate sperm production. The aim of this study is to determine the target level of changes on ejaculatory physiology under hyperthyroid states. Subcutaneous injection of Hypothyroidism And Sex Drive for 14 days was performed to induce hyperthyroidism. At the end of the injection period, thyroid hormone status was evaluated by serum thyroid-stimulating hormone measurements in all rats. At the beginning of the operations, complete spinal transections tx at the T8-T9 level were performed to half of the L-thyroxine-injected and control group rats. Main Outcome Measures. The time interval between PCA administration and first ejaculation of hyperthyroid intact rats were significantly shorter than control intact Hypothyroidism And Sex Drive Ϯ 7. All of the changes in the ejaculatory parameters that were induced by hyperthyroidism were completely resolved after spinal transections at the T8-T9 level in group 4. In this study, we confirmed the recent data that hyperthyroidism affects Hypothyroidism And Sex Drive the emission and expulsion phases of ejaculation. The changes that were induced by hyperthyroidism on ejaculatory physiology probably take place in the supraspinal centers above T8 level. Investigation of the neural target level of hyperthyroidism in premature ejaculation in a rat model of pharmacologically induced ejaculation. J Sex Med ; Animals were divided into three groups and given small bilateral lesions in the dorsomedial preoptic area POAventromedial hypothalamus VMHor sham operations. Starting 10 days postsurgery, all animals were injected with estrogen alone and estrogen plus progesterone, and tested twice for lordosis behavior. Ten days following the female behavior tests, animals were injected daily with testosterone propionate for 13 days and tested for masculine sexual behavior on injection days 5. Low levels of lordotic behavior were observed for POA and VMH animals on both tests for female sex behavior and were comparable to sham operated animals. In contrast, POA lesioned rats showed little or no male sex behavior on any test and were significantly inferior to sham operated animals. Thus, the POA and VMH appear to exert excitatory and inhibitory control, respectively, over male copulatory behavior in male rats. Background: Up until now, the effect of thyroid hormones on the male reproductive organ, after puberty, is not well understood. After 4-months we examined the number of spermatogonia cells, primary spermatocytes, and Sertoli cells, as well as the seminiferous tubules epithelium thickness, area of seminiferous tubules, and the diameter and Hypothyroidism And Sex Drive of testis artery walls. RESULTS: No significant difference was observed between the hypothyroid and control rats in terms of the area of seminiferous tubules, the number of spermatogonia cells, primary spermatocytes, and Sertoli cells. Moreover, the epithelium thickness of seminiferous tubules and the diameter and thickness of artery wall
