Penile erection is homodynamic procedure mediated by neuron-endocrine system,and the relaxation of smooth muscle of the corpus cavernosum(CC) and its associated arterioles plays a key role in penile erection.
RESULT Haima Zhuangyang Capsule can reduce the body weight of rats, increase their autonomous activities, prolong swimming time, markedly shorten the incubation period for the erection of penis of mice and increase the mating ability of normal male rats.
Method: The influence of extract from Chinese chive seed on the erection of penis of was investigated in adult male rats with experimental insufficiency of the kidney-yang produced by both removal of double spermaries and high dose of hydrocortisone.
Results: BX capsule could obviously raise the concentration of serum testosterone and cortisol, and the coefficient of sex organ in rats, and increase the number of sperm and interstitial cells in mice. Also, it could improve the penis erection and sexual ability of the male rats.
BCJ could significantly raise the excitability and sensitivity of mice's penis to extrinsic stimulation, decrease the latent period of penis erection, significantly increase castrated mice's preputial gland index, seminal capsule gland + prostate gland index and musculus levator index.
METHODS:Fifty four experimental rats were randomly divided into seven groups(three control groups),and then each group was subdivided into 6-7 groups. The sexual gland index,the latency of penis erection and the ability of copulation after ovariectomized were measured in each group,and the differences of them between the groups were compared.
It can enhance the sexuality and reinforce erection of rats too. The results suggest that the effect mechanism of incariin have great relation not only to its increasing the male hormone level and the content and activity of monoamine neurotransmitter in rats ' hypothalamus but also to its improving the erectile tissue structure, increasing the content of eNOS and decreasing the content of ET-1 expressed in the corpus cavemosum of the rats' penis.
Female choice was indicated when they performed a "penis erection check" or took the initiative in courtship, or on the other hand showed strong reluctance to mate with particular males.
The release of nitric oxide from the cavernosal nerve is a key step in the physiological process of penis erection during sexual stimulation.
The phaizna'codynamica of Zhuang Yuan Dan tZYD),a recipe of herbal medicine, wasstudiedThe results showed that various dosages of ZYD c`i`n increasethe excitability of castraled rats towardexternal stimuli,shorten the latent period of penial erection,counteract estradiol, relieve yangdeficiencysyndrome,and also exerts antifatigue and immunoenhancement effects.It is indicated thatZTh isapplicable to deficiency of kidney-yang,immunologic inadequacy and sexual disorder in males.
SenrongQiangli capsule was observed to prolong incubation period qerection andpromote sexual performance ability in unsexed rats,The capsule could increase spontaueous activ-ity, swimming stamina in low temperature water,and body weight in the mice with Yang-difi-ciency. The higher level of testosterone in serum of normal rats and the vigorous growth of somesexual organs were observed in the unsexed mice.
Xianyang oral liquid can promote the growth of underaged male mice and their sexual organs by oral administration, increase the weight of phimosis gland of castrated rats, decrease the weight ratio of anus levator muscle/prostate which means that the muscletropism activity decreases and the hormone activity increases. The liquid can also obviously enhance the blood testosterone quantity and the weight of sperm bladders of castrated rats, decrease the latent period of penis erection.
