Testis penis size and relation between marriage and childbirth

Testis, penis size and relation between marriage and childbirth
The testis is a male gonad, can produce sperm and sex hormone. The penis, for handing in shutting the organ of the man. The normal value of canvassing they from sex and parenting function foundation is studied very few on the literature, lack epidemiology to investigate even more. For this reason, we, on January to May, 1991, until sexual life and parenting situation were gone on, followed up a case by regular visits to after marriage in make testis, 920 the intersection of premarital checkup and man that penis measure 1988, 868 brief summaries following up a case by regular visits to now discuss as follows: First, respondent: Have done testis, penis measuring and whole body physical examination in 1988 premarital checkup, it is unusual 23-37 years old with the healthy man of reproductive system disease that there is no endocrine, and already been married for more than two years. Second, follow up a case by regular visits to the method: Adopt the closing questionnaire, including two respects and altogether 18 items of sexual life and parenting are quized, through posting a letter, telephone is available and inquire three kinds of routes follow up a case by regular visits to to the doorstep. Third, follow up a case by regular visits to content and standard: Follow up a case by regular visits to the content and adopt the unified standard made in advance, the penis can be inserted in the vagina, and the persons who can ejaculate in the vagina call the sexual life normally; It is abnormal on the contrary. Cohabit, take contraceptive any two year while being full after marriage and spouse getting pregnant to call sterility; Pregnant, including miscarrying naturally, ectopic pregnancy, induced abortion and giving a birth etc. to all deem to become pregnant normally. Fourth, count and deal with: All materials use SPSS software to deal with on AST386 plane. Result one, target's characteristic: Several 900 total examples, follow up a case by regular visits to several 868, following up a case by regular visits to rate is 96.44%, age followed up a case by regular visits to, job, testis, penis measuring value distribution situation are as follows: 1. Age: The 23 years most younger, the 37 years most older, 28.9 average years olds. Among them 528 for 26-30 years old, take 60.83% (See tables one) Table one Age and parenting relation Age (years old) The example is counted Practise contraception Become pregnant Sterility The example counts % The example counts % The example counts % 0.05). Third, situation of becoming pregnant: Take the intersection of contraceptive and over two o'clock person 63 after marriage, account for 7.26%, become pregnant 755 in the remaining 805, become pregnant rate 93.79%, 50 of sterility, sterility rate 6.21%. The sterility rate dealt with among different ages, job, testis volume and penis length by statistics does not have a prominent difference (P> 0.05) . One discussion, protect in the clinic can run into, tell own penis little by some youth oftenning in wedding, it is not so big as the others' one, it influences the sexual life after marriage to worry about. In fact to most persons, this kind of worry is totally unnecessary. Research proves, 2/3 parts are neural there is few end on women's vaginal wall, it mainly oozes out and secretes the liquid in the sex excitement one, drip the slippery vagina. Insert the penis and does not basically keep in touch with the vaginal wall of this part, even keep in touch, do not have important function in producing the orgasm. And the neural ends of 1/3 of the parts are very abundant under the vaginal wall. It is the most sensitive part in the sexual organ, in the course of sexual intercourse, penis and this sensitive position rub, irritate neural end, make women obtain pleasant sensation. So the man's penis only stimulates playing 1/3 of the parts of the vagina, for instance, both sides cooperate well, will not influence the orgasm to appear. This group penis length is 3-5 centimetre normally,person there is an life abnormal at 53 cases, and the length is greater than abnormal 5 for 815 cases of neutral life of 5 centimetres, accounts for 0.61%. Penis erect difficult 2 among them, ejaculate too fast 2, sexual intercourse ejaculate 1 disease. Penis erect difficult 2, one is bad because of living conditions, elder brothers of parents cohabit in room one; 1 were handed in to the person who does not ejaculate in sexual intercourse the penis has not twitched. The above-mentioned 3 have guide been and has alreadied fully recovered. 2 persons who ejaculate too fast, cut postoperative symptom and improve in a customary foreskin ring; Another clear reason, competent traditional Chinese medicine treatment. The abnormal rate of the sexual life after marriage of this group is on the low side, it is analyzed that perhaps there are two factors: First, the interviewee has already accepted the knowledge propaganda and education of the marriage and childbirth, second the sex knowledge in the society in recent years in the premarital checkup, there are more popular science articles of the sex skill. Dealt with by statistics, the sexual life is too abnormal to have relevant relation with the interviewee's age, job, testis volume, all kinds of value of penis length, investigation prove the intersection of penis and length penis length 6 more than healthy man under the state in erect by 3 or negative pressure normally, the great majority all have a normal sexual life. Second, testis volume and a lot of indexes of testis function have prominent relevance. Because 95% of the testis volume are grown sperm's tube to form, so correlated with with the quality and quantity of the sperm particularly obviously. Thorneycroft reports testis volume and sperm's density and percentage of the normal shape are the positive correlation, have nothing to do with the seminal fluid capacity or energy percentage, the sterile man's testis volume is obviously smaller [2 ]. The literature reports the critical value of the testis volume rises for 12 Bo [3 ], reports such as Zhang SiXiao,etc. are 10.15 ml, or the intersection of people and the intersection of testis and volume smaller than value this, should consider it grow precise function lower than getting normal this group the intersection of testis and volume less than ml of 122s while being clinical, get rid of, practise contraception 6 exceptions, the sterility rate is 6.89%. The testis volume is greater than 746 of 10 ml, 57 exceptions that get rid of and practise contraception, the sterility rate is 6.09%. Though the intersection of testis and volume smaller than 10 the intersection of group and sterility take place one hundred compare the intersection of testis and volume it greater than 10 groups to be high, it does not have prominent difference (P> 0.05) but dealt with two groups by statistics . This may one because this group sample count partial and light; Second, testis volume large to might have because of other disease too in 10 group sterility person. So have its certain limitation to comment on man's sterile card simply and from testis volume. The morbidity of third, male sterility, there are many foreign reports, the figure is different too. The intersection of Japan and one male the intersection of sterility and 894, account for, secrete the intersection of urine and department, go to a doctor 9.4% that count while being ill while being new, the first visit is the most 25-34 years old, sterility of about 10% of the married couple of the American report, 20-25% among them are reasons of both sides, 20-25% are caused by the husband, the others are the wife's reason. There are little morbidity reports about male sterility of our country [5 ]. Group this 2 years sterility rate is 6.21% after marriage, lower than the above-mentioned report. Perhaps this group target are a healthy man for the reason, endocrine and reproduction department person who has disease have not been included in this group of investigations. Sterile reason: The husband causes 14, accounts for 28%, 5 seminal fluid quality problems among them, without 4 sperm's diseases, 3 sex questions, do not penetrate Precise disease and cancer are one respectively. 17 the wife's factors, accounts for 34%; Hypothalamic - heavy body - messy 6 of ovarian function rate among them, 4 ovarian tumours, 3 membrane malposition diseases in the uterus, the number of the oviduct is obstructed 3, 1 case of anaemia. 3 reasons that of both sides, accounts for 6%. The number of the reason is unidentified 16, accounts for 32%. Group this become pregnant 755, normal the intersection of gestation and 738 among them, accounts for 97.7%, 3 cases of induced abortion, accounts for 0.39%; Miscarry 10 naturally, account for 1.3%; 4 cases of ectopic pregnancy, accounts for 0.5%; Become pregnant 723 in the one year after marriage, account for 95.76%. Dealt with by statistics, rate, sterility rate and the interviewee's body of age, job, testis of becoming pregnant
