PURPOSE: The purpose of this study was to investigate the effects of pelvic floor muscle exercise using electric stimulation and biofeedback on maximum pressure of vaginal contraction, vaginal contraction duration and sexual function in women who have had vaginal rejuvenation. METHODS: The research design was a non-equivalent control group non-synchronized design study. Participants in this study were women who had vaginal rejuvenation at C obstetrics and gynecology hospital. The 15 participants in the experimental group were given pelvic floor muscle exercise using electric stimulation and biofeedback and the 15 participants in the control group received self pelvic floor muscle exercise. RESULTS: For maximum pressure of vaginal contraction, the experimental group showed a statistically significant increase compared to than the control group (t=5.96, p<.001). For vaginal contraction duration, the experimental group also showed a statistically significant increase compared to the control group (t=3.23, p=.003). For women's sexual function, the experimental group showed a significant increase when compared to the control group in total sexual function scores (t=3.41, p=.002). CONCLUSION: The results indicate that pelvic floor muscle exercise with electric stimulation and biofeedback after vaginal rejuvenation is effective in strengthening vaginal contraction pressure, vaginal contraction and that it also positively functions to increase women's sexual function.

OBJECTIVE: compare quality of life (QoL) and sexual functioning between sexually active ovarian cancer survivors and healthy women. METHODS: A cross-sectional study was performed in 103 successfully treated ovarian cancer survivors and 220 healthy women. All women had engaged in sexual activity within the previous 3 months, and ovarian cancer survivors were under surveillance after primary treatment without evidence of disease. QoL and sexual functioning were assessed using three questionnaires; the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), Ovarian Cancer Module (EORTC QLQ-OV28), and the Female Sexual Function Index (FSFI). Propensity score matching was used to adjust covariates between the ovarian cancer survivor and healthy women groups. In total, 73 ovarian cancer survivors and 73 healthy women were compared. RESULTS: Poorer social functioning (mean, 82.4 vs. 90.9; p=0.010) and more financial difficulties (mean, 16.4 vs. 7.8; p=0.019) were observed among ovarian cancer survivors than among healthy women. Sexuality, both in terms of desire, arousal, lubrication, orgasm, satisfaction, and pain and in terms of interest in sex, sexual activity, and enjoyment of sex (EORTC QLQ-OV28) were similar between the groups. However, vaginal dryness was more problematic in ovarian cancer survivors, with borderline statistical significance (p=0.081). CONCLUSION: Sexuality was not impaired in ovarian cancer survivors who were without evidence of disease after primary treatment and having sexual activities, compared with healthy women, whereas social functioning and financial status did deteriorate. Prospective cohort studies are needed.

OBJECTIVETo investigate how network education can improve college students' knowledge on sexual and reproductive health in Ningbo city.

METHODSFrom December 2012 to June 2013, we conducted a questionnaire investigation among college students in Ningbo city about the effects of network education on their knowledge about sexual psychology, sexual physiology, sexual ethics, and reproductive health.

RESULTSA total of 7 362 college students accomplished the investigation, of whom 2 483 (42.1% males and 57.9% females) received network education, while the other 4 879 (24.1% males and 75.9% females) did not. Approximately 47.1% of the male and 28.0% of the female students acquired sexual and reproductive knowledge via network education. Reproductive health-related network education significantly enriched the students' knowledge about the reproductive system and sex, pubertal development, sexual physiology, conception and embryonic development, methods of contraception, sexual psychology, sexually transmitted diseases and their prevention, pregnancy care and eugenics, and environment- and occupation-related reproductive health (P < 0.01). It also remarkably improved their cognitive attitude towards reproductive health knowledge (P < 0.01). Those who received reproductive health-related network education showed a significantly higher rate of masturbation (P < 0.01) but markedly later time of the first masturbation (P < 0.01) than those who did not.

CONCLUSIONNetwork education can enhance the effect of reproductive health education among college students and improve their sexual experience and health.

AIMTo investigate the influence of an extract obtained from five Chinese medicinal plants on sexual behavior of adult male rats.

METHODSThe extract was administered at doses of 30, 60 and 120 mg/kg by oral gavage, acutely (one time, 45 min before mating test) or subchronically (daily for 10 days) in sexually potent and sexually sluggish/impotent rats. Sexual behavior, serum levels of luteinizing hormone (LH) and testosterone (T) were evaluated in treated rats and compared with controls receiving vehicle. The effect of the extract on central dopaminergic neurotransmission was assessed in the nucleus accumbens using a microdialysis technique.

RESULTSIn sexually potent rats, both acute and subchronic treatment with the extract dosed at 30 and 60 mg/kg reduced mount latency and intromission latency. In sluggish/impotent rats, the acutely administered extract at the dose of 60 mg/kg shortened ejaculation latency, whereas subchronically administered at the doses of 30 and 60 mg/kg, reduced mount, intromission and ejaculation latencies, increasing also the percentage of mounting and ejaculating rats. The extract dosed at 60 mg/kg significantly increased LH and T following acute and subchronic administration and increased 3,4-dihydroxyphenylacetic acid levels in the nucleus accumbens, 30 min after the acute administration.

CONCLUSIONThe improvement in both appetitive and consummatory components of sexual behavior observed in male rats treated with the extract could be ascribed to increased serum T level in parallel with the activation of the central dopaminergic system.

OBJECTIVETo evaluate the type V phosphodiesterase (PDE-5) inhibitor erection-provoking test with audio-visual sexual stimulation in the diagnosis of erectile dysfunction.

METHODSA total of 853 out-patients diagnosed with erectile dysfunction were divided into an injury and a non-injury group. After scored on IIEF-5 questionnaires, all the patients received oral administration of PDE-5 inhibitors and, 30 minutes later, audio-visual sexual stimulation. The data on penile erection were recorded with Rigiscan Plus.

RESULTSThe patients with mild, moderate and severe ED accounted for 18.8, 31.9 and 49.3% in the injury group, and 50.6, 39.8 and 9.6% in the non-injury group, with statistic differences between the two groups in the mild and severe parts (P < 0.05). The rates of conspicuous effectiveness, effectiveness, ineffectiveness and total effectiveness of the combined method were 13.0, 14.5, 72.5 and 27.5% in the injury group, but 55.7, 20.7, 23.6 and 76.4% in the non-injury group, with significant differences (P < 0.05).

CONCLUSIONThe PDE-5 inhibitor erection-provoking test with audio-visual sexual stimulation is a simple, practical, safe and effective method for the differentiation of organic from psychological erectile dysfunction.

OBJECTIVETo understand the sexual physiology and psychology of male college students and to provide schools, families and the society with reference for the sexual physiological and psychological education among college students as well as for the diagnosis and treatment of their sexual psychological disorders in Jiangsu.

METHODSAn investigation was conducted by using a questionnaire on sexual physiology and psychology among randomly selected 3786 male college students from 18 universities in Jiangsu.

RESULTSAs regards sexual education, 5.49% of the subjects were satisfied with their schools, 78.18% wanted it to be strengthened and 68.36% obtained their sexual knowledge from the internet. Concerning sexual physiology, 68.78% experienced their first spermatorrhea at the age of 12-15. As for sexual psychology, 85.79% loved a certain female inwardly, and 70.99% experienced love affairs. With regard to sexual activity, 25.54% had sexual experience.

CONCLUSIONCollege students nowadays are relatively open in sexual ideology, immature in sexual psychology and lacking in sexual knowledge, while schools are inefficient in sexual education. Their sexual health calls for joint attention from schools, families and the society, particularly schools, which need to establish special offices for research and education on sexual health.

OBJECTIVETo investigate the effects of kidney-jing deficiency on the fertility of male mice and their male offspring.

METHODSThirty 6-week-old Kunming male mice and 300 female ones were randomly allocated to a blank control group, a model group and a kidney-tonifying group. The model and the kidney-tonifying groups were stressed by fear plus excessive sex to establish a kidney-jing deficiency model, and meanwhile the latter were given concentrated solution of Kidney-tonifying Recipe intragastrically at the dose of 0.16 ml/10 g. The control and the model groups were treated with physiological saline at the same dose for 21 days. Then all the male mice were mated with the healthy estrous females for 5 days. The sperm density and motility of each group of the male mice were examined, and their fertility was assessed by comparison of the pregnancy rate and the number of baby mice at each birth among their female mates. And the sperm density and motility of the male offspring were detected at 6 weeks.

RESULTSThe average number of baby mice at each birth in the model group was (7.00 +/- 1.73), significantly smaller than those in the control (9.43 +/- 1.27) and the kidney-tonifying group (8.80 +/- 1.10) (P < 0.05). The sperm density and motility of the model mice were (9.70 +/- 1.15) x 10(6) / ml and (66.72 +/- 10. 12) %, lower than those of the control ([14.08 +/- 1.15 x 10(6)/ ml and [81.75 +/- 3.56] %), and the kidney-tonifying group ([12.20 +/- 1.55] x 10(6)/ ml and [78.55 +/- 4.38] %) (P < 0.05). There was no significant difference between the latter two groups (P > 0.05). The sperm density and motility of the offspring of the model mice were (10.10 +/- 1.79) x 10(6)/ ml and (71.86 +/- 7.48) %, lower than those of the control ([15.30 +/- 1.83] x 10(6)/ ml and [79.86 +/- 5.68] %), and the kidney-tonifying group ([14.20 +/- 2.21] x 10(6)/ ml and [81.92 +/- 2.51] %) (P < 0.05), with no significant difference between the latter two groups (P > 0.05).

CONCLUSIONFear plus excessive sex could reduce the fertility of male mice and even that of their male offspring. And kidney-tonifying therapy could counteract this effect.

Human sexuality has both its sociological nature and biological nature. Advances in molecular biology has unveiled almost all the biological mysteries of human sexuality. However, many problems in the psychological and sociological aspects have not yet been thoroughly studied. As a matter of fact, these psychological and sociological factors have much influence on sexuality than those biological ones. This paper briefly introduces some factors affecting male sexual psychology, including masturbation and other common sexual psychological dysfunctions.

OBJECTIVETo study the contribution of puberty maturation to smoking behavior in Chinese adolescents.

METHODSA cross-sectional survey was carried out. One thousand four hundred and fifty-three senior middle school students aged from 15 - 18 years were recruited in Shanghai in 2000. A standardized self-administrated questionnaire was designed to obtain information on smoking, age at first nocturnal ejaculation in boys, age at menarche in girls and variables that might be associated with smoking in adolescents.

RESULTSIn boys, the prevalence of experimental smoking was highest among later maturers (28.6%), followed by the earlier (21.3%) and the average (21.7%), and the prevalence of current smoking was highest among earlier maturers (16.4%), followed by the later (7.1%) and then the average (4.8%). In girls, the prevalence of ever smoked among earlier, average and later maturers were as follows: 24.2%, 12.0%, 6.3% respectively. When psychosocial variables which might be associated with smoking were under control, early maturation was a significant risk factor for current smoking in boys (OR = 3.68, 95% CI: 1.23 - 10.99), and might be a risk factor for ever smoked in girls (OR = 2.23, 95% CI: 0.89 - 5.60). Whereas late maturation might have been a risk factor for boys to experiment smoking (OR = 1.48, 95% CI: 0.72 - 3.06), while in girls it might be protective (OR = 0.64, 95% CI: 0.22 - 1.86).

CONCLUSIONEarlier or later matured boys and earlier matured girls were at higher risk of smoking. Pubertal changes and timing need to be considered in smoking prevention.

OBJECTIVESTo investigate the status of pre-marital reproductive health education, sexual psychology behavior, contraception and pre-marital abortion in unmarried young men to get the correct way for pre-marital guidence and education.

METHODSThe survey adopted the society-psychology-behavior methodology. Five hundred and ten objects who had pre-marital sexual living history were investigated randomly.

RESULTSThe reasons of making sexual pre-marital relations were thinking marriage and curiosity. 81.2% of them thought the best way of contraception is to use the condom. 34.8% of them used the prevenception when they had the first sexual experience. 39.7% of the objects adopted contraceptions every time, and 27.1% of the objects made the women pregnancy which resulted 22.4% women using the IUD for contraception. 63.6% of them thought the main reason of not using contraception was the fear to get trouble. The main source of contraceptives was pharmacy (59.8%).

CONCLUSIONSThis survey suggested that the prevalence of pre-marital sexual behavior is relatively high in Changshu. It should be taken several methods to give unmarried young men the reproductibe education.
