This study aimed to compare premature ejaculation and erectile function according to penile characteristics. 99 adult men responded to a questionnaire on penile characteristics, premature ejaculation and erectile function. In the questionnaire survey, 69 questionnaires were analyzed except missing or incomplete answers. All collected data were analyzed by independent t test, Chi-square test using SPSS 22. Glans > penis type showed significant differences in subjective premature ejaculation and objective premature ejaculation compared to Glans ${\frac{._-}{.}$ penis type (p <.05). Men with subjective premature ejaculation showed significant differences in objective premature ejaculation, treatment intent, and satisfaction compared to men without subjective premature ejaculation (p <.05). Presence of objective premature ejaculation, presence of treatment intent, and marital status were significantly different in satisfaction (p <.05). In economic status, high was significantly different in confidence for erectile function compared to middle or low (p <.05). The results of this study suggest that the premature ejaculation and erectile function according to the penile characteristic may be different and may be used as a basis for the development of an intervention program for sexual rehabilitation of men with premature ejaculation and erectile dysfunction.

Premature ejaculation is the most common sexual dysfunction seen in the male, and it is found in 30 to 50% adult male population. It is defined as the inability to control the ejaculatory process for a sufficient length of time during intravaginal containment to satisfy his partner in at least fifty percent of his coital connections The majority of men with premature ejaculation have underlying psychologic origin of performance-anxiety type, but it is not always psychogenic and may also be a presenting symptom in certain organic disorders. In oriental medicine, the point of treatment of premature ejaculation is recovery of the good ejaculatory control, and the treatment can be approached in three ways as psychological therapy involving behavioral therapy, herb drugs, and acupuncture. This study has aims to investigate and summarize the current trend of treatment for premature ejaculation so as to suggest the effective and available way to treat the disease.

The objective of this study were to investigate the effect of ejaculation frequency on semen characteristics and to establish a method for quick assessment of sperm concentration in TCC using packed cell volume (PCV) as the parameter (Trial 1). Eighty senior roosters, averaging 61 wk-old, were used and the sperm concentrations were determined using a hemacytometer. The PCV value was measured in a capillary (0.75 mm in inner diameter) by centrifugation. A simple linear regression analysis suggested that the sperm concentrations were significantly correlated with PCV values (r=0.62, p<0.001). Trial 2 was conducted to determine the optimal ejaculation frequency of TCC roosters in a weekly semen collection program. The male birds were subjected to 1, 2, 3 or 6 ejaculations per week for four consecutive weeks and semen characteristics including ejaculation volume (EV, mL), sperm motility (%), PCV (%), sperm concentration (ESC, $\times$10$^{9}$/mL), weekly sperm production (WSP, $\times$10$^{9}$/wk) and average motile sperm numbers (AMSN, $\times$10$^{9}$/ejac) were determined. Average EV was greater in the group with 3 ejac/wk than with only 1 ejac/wk in weeks 1 and 3 of the collection period. WSP increased with ejaculation frequency during the first 3 weeks of collection (p<0.05). Sperm motility was better in the birds with 6 ejac/wk than in single ejaculation group for the first 2 wk and no significant differences were found for the last 2 wk of study. In contrast, the PCV value showed a trend of reduction for the first 2 wks in the 6 ejac/wk group. Surprisingly, no significant differences were detected in the AMSN among treatment groups. The weekly motile sperm production (WMSP) increased with ejaculation frequency. Based on our observation, PCV values could be used for a quick estimation of sperm concentration and an intensive semen collection program enhanced weekly sperm production in TCC roosters.

Retrograde ejaculation is a condition that causes male infertility. Infertiltiy treatment is usually based on assisted reproductive technology with the use of sperms recovered from the bladder after ejaculation. Many pregnancies have been tried by artificial intrauterine insemination with the husband's sperm recovered from voided urine. In this case, ovulation was induced by clomiphene citrate and human menopausal gonadotropin, pH and osmorality of urine was controlled by modified Ham's F-10 contained 10% serum substitute supplement and immediately semen collection, to improve sperm motility. We had experienced a successful pregnancy case by above method, and reported with brief review of literature as well.

Tricyclic antidepressant clomipramine or selective serotonin reuptake inhibitors (SSRIs) have been commonly used for the treatment of premature ejaculation. In the present study, we analyzed the concentrations of serotonin and 5-hydroxyindoleacetic acid (5-HIAA) in the medial preoptic area (MPOA) of the hypothalamus by awakening animal microdialysis following administration of clomipramine and various SSRIs. We then compared the serotonin metabolism and clinical effects of clomipramine and SSRIs on premature ejaculation. Basal extracellular serotonin level in the MPOA was higher than other brain regions and it was significantly increased by clomipramine and the SSRIs. The rank order of the concentration of serotonin at the MPOA was clomipramine, sertraline, paroxetine and fluoxetine and the concentrations of 5-HIAA was vice versa. The changes in serotonin concentration at the MPOA appeared closely associated with the clinical effects of these drugs on premature ejaculation. These results suggest that the serotonergic neuronal activity in the MPOA may have an selective inhibitory influence on ejaculation, and the effects of clomipramine and SSRIs on erectile function are mainly mediated by MPOA of the hypothalamus.

Reproductive activity in the economically important insect, Antheraea mylitta is very important because the female reproduces only once in her life time and the aging is very rapid and costly. It is a capital breeder and strictly a monoandrous species. To know how strategically the insect behaves and the male allocates its ejaculate resource more prudently during its successive mating with virgin females to maximize its own fitness and the fitness of the female with whom it mated, both being most important to sericulture industry. So, the present study was undertaken and the results revealed fresh and virgin females always prefer to mate with fresh virgin males (84%) and receives high dose of ejaculates leading to higher hatchability than to virgin males of one day old (13.7%) and one day old males with mating experience (2.3%). The ejaculation size (as referred to eupyrene sperm count in the ejaculation) declined significantly over successive mating (r = -0.9931, P < 0.001), so also the male body weight (r = -0.9560, P < 0.001). The quantity of ejaculate passed to female also dramatically declined during aging (r = -0.9982, P < 0.001). It was found that male weight contribute substantially to the quantum of ejaculate (r = -0.9519, P < 0.001), so also higher fecund females receive relatively more ejaculate than the lower group to reach higher reproductive fitness. The life time fecundity was found to be $334{\pm}31$.

Background: To investigate the prevalence of premature ejaculation (PE) and erectile dysfunction (ED) in a sample of patients with prostate cancer and to determine the utility of the previously suggested cutoffs of the Premature Ejaculation Diagnostic Tool (PEDT) for the diagnosis of PE and that of International Index of Erectile Function (IIEF-5) for ED. Materials and Methods: A total of 1,202 men with prostate cancer were invited from urology clinics at the universities of Iran, Tehran, Qazvin, Ahvaz, Guilan and Tabriz. Clinical characteristics were collected through medical records. PE and ED diagnoses were made by trained urologists. In addition to the clinical diagnoses, PE and ED were measured through self-report using the PEDT and the IIEF-5. Questionnaire cutoff scores were determined using receiver operating characteristic (ROC) curves and confirmed by predictive ability using logistic regression. Results: The prevalence of PE was 63.7% and that of ED was 66.2%. Prevalences of PE decreased and that of ED increased with advanced TNM stages. According to ROC, the suggested cutoff for the PEDT to diagnose a PE was ${\geq}11$ (sensitivity=0.988, 1-specificity=0.084, and predictive ability=0.914) and ${\leq}17$ for the IIEF-5 (sensitivity=0.966, 1-specificity=0.031, and predictive ability=0.967). Conclusions: Prevalence of sexual problems was high in prostate cancer patients in Iran, therefore oncologists should take into account these potential problems when deciding on treatment modalities.

Background : The purpose of this study is to find out the impact of kinesio-taping method for female university students, who are vulnerable to constipation, on the activation of intestine. Methods : This study has been conducted for a total of three weeks including the pre-inspection, and it explained the purpose of the study upon selecting the adequate subjects who met the criteria for constipation among the female students. And It chose the nine students, who agreed to the experiment, as the subjects. It verified the frequency and time of excretion before experiment and the constipation ejaculation measure, and compared pre-arbitration with post-arbitration as for the time and frequency of excrement, the point of constipation ejaculation measure, etc. after two weeks since the application of tape. Result : The frequency of excrement after arbitration increased compared with pre-arbitration as result of the application of kinesio-taping method, and the time, which was taken for excrement, decreased. It was also shown that the point decreased in the point comparison for constipation ejaculation measure; thus, it obtained the result that showed the improvement of the level of constipation and all were statistically significant(p<.05). Conclusion : It is believed that kinesio-taping method has a positive impact on the activation of intestine of female university students.

The influence, upon male rat's mating behavior, of Korean Panax Ginseng administered for 3 and 5 days was investigated by direct behavioral observation and also by counting the number of copulation plugs the animals deposited. Four쇼-four male albino rats were used. Part of the animals received ginseng for 3 days (ginseng-3 day group, N= 12) or for 5 days(ginseng-5 day group, H=10), while the remaining animals received saline for 3 days (saline-3 day group, N=12) or for 5 days (saline-S day group, N=10). Each animal belonging to the 2 ginseng groups received subcutaneously 0.5 ml/100 g body weight of ginseng alcohol extract solution (4 mg of the ethyl alcohol extract in 1 ml of physiological saline), and each rat belonging to the 2 saline groups received the same amount of saline per day. During the dark period of the light-dark cycle on the next day following the last drug administration, a female rat in the artificial estrus was introduced to each male and the mating behavior was observed for 45 minutes. The observation session was divided into two parts and, in the early part which terminated with the first ejaculation and succeeding intromission, following behavioral measures were taken: mounting latency, intromission latency, inter-intromission period, ejaculatory latency(time from the first intromission until the first ejaculation), occurrence of mounting with intromission, occurrence of mounting without intromission, and postejaculatory interval. Behavioral measures taken in the later part of the session after the first ejaculation were: occurrence of mounting with intromission, occurrence of mounting without intromission, and occurrence of ejaculation. Immediately after the behavioral observation session the experiment turned to measure, for 10 days, the number of copulation plug which each pair of rats deposited. Following results were obtained: 1. After several mountings mounting with intromission, males of the 2 ginseng groups finished the first ejaculation significantly earlier than the corresponding 2 saline groups did. 2. The postejaculatory latency was significantly reduced in the ginseng-5 day group compare with the value of the saline-5 day group and also compared with the value of the ginseng-3 day group. 3. The 2 ginseng groups ejaculated significantly more often in 45 minutes' observation session than the corresponding 2 saline groups did. 4. The number of copulation plug deposited in 10 days by the animals of the 2 ginseng groups. significantly exceeded the number deposited by the corresponding 2 saline group animals. The animals of the ginseng-5 day group deposited copulation plugs significantly more than the animals of the ginseng-3 day group did. It is inferred from the above results that the ginseng facilitates mating behavior of male rats, and that the degree of facilitation may be influenced by the duration of drug administration.
