 The Sperm how long can live in the women body Sperm are humans thrive of the material, the factory system of testicular sperm weight is about 10.5 ~ 10.5 grams, surrounded by white film packages, which surrounds the 250 ~ 400 lobular, each leaf of 1 ~ 4 hovering seminiferous tubule, wast a diameter of 50 microns, mature increases to 170 microns.1 piece, the total length of seminiferous tubule in testis unilateral for 255 meters.Per gram of testicular tissue about release 10 million sperm every day.Due to the female's ovulation each are not identical, and sexual intercourse, not necessarily it's the time to ask sperm must wait for eggs, in order to increase the opportunity to meet.So the sperm in female reproductive tract survival time length have important relationship with fertility.1, the sperm in female reproductive tract remaining time:Vaginal acid fluids for ordinary pH3.5-4.Although theoretically as long as there is a live sperm can be fertilised, but in fact in the vagina of acidic conditions, most of the sperm into the vagina soon died.Only under a certain amount of semen buffer, is likely to make a few strong vitality of sperm survival time lengthen, gain access to the uterus and fertilization.Without a lot of sperm sacrifice, without a certain amount of semen buffer improve the acid and alkali environment of the vagina, a single sperm or very little few sperm in the vagina is impossible to survive in the acidic environment and fertilization.Under normal circumstances, the survival time of sperm in the vagina is: 2 hours after sexual intercourse, 90%;36 hours, even death can't see.Sperm in the vagina of pregnant women, the stronger the acidity of the faster the death.2, sperm cervix and remaining time:The change of the acidity in the cervical mucus, has a great influence on the sperm through.PH less than 6.5, sperm stop activities, pH7, mild wear into the ability to initiate pH7.5, through normal abilities, pH8.2 through ability is stronger.Outside the cervical mouth has a lot of mucous congestion, caused many sperm can't wear into the die outside.Cervical mucus during menstruation just out of date and thick and tough;When close to ovulation, because female hormones in the blood increases, mucus more, clearing, spins increased;At the time of ovulation, mucus quantity more, clearing, outflows, sperm is easy to wear.Sperm to penetrate the cervical mucus, depend on enzyme hydrolysis.Pancreatic protein undergraduate chymotrypsin and hyaluronidase can hydrolyze the cervical mucus, lower viscosity, loss of ropiness formation, and is conducive to sperm.In general, the sperm in the cervix and survival time is: within the cervix, sexual intercourse after 15 minutes, can be found in the cervical mucus sperm;Within an hour later, the sperm into the mouth;1 hours after sexual intercourse in the womb, intrauterine with sperm, after 6 hours, all the activities of sperm, 5/6 of the sperm still alive after 12 hours, 36 hours after a quarter of the sperm is still alive, after three days, no live.But sometimes there are some sperm survival time were particularly long.3, sperm in the remaining time within the fallopian tube:Within the fallopian tubes, sexual intercourse after 14 hours has the activity of sperm, 35 days still sometimes have live sperm, generally are the most active for 14 days, some into the abdominal cavity.Bradykinesia, are cilia flow back to the uterus.The sex knowledge which we need to know People are enjoying their pleasure at the same time, should also be correct for the incorrect ideas in sex, a harmonious sex life can make men and women both parties can get the sublimation of the highest in physiology and psychology, the following points hope to be of help.A, frequency of sexSexual intercourse frequency exactly how much is appropriate, this is a question difficult to answer.Every man on the strength of the different sex, even if the same person is influenced by age, physical condition, character, occupation, climate, environment, emotion and other factors.As a result, the number of sex cannot mechanically regulation, and to adjust according to the specific situation.During the wedding, sexual desire is more intense, number of sex more frequently.The first few months after marriage, usually 2 ~ 3 times a week.As the growth of the age, will be gradually reduced to 1 ~ 2 times on Monday.Body is poorer, the number is less.Couple reunited, often sexual intercourse frequency, it is human nature, but also to appropriate restraint.Sex is moderate, can use the intercourse feeling as the judgment standard.If both sides don't feel tired, but feel love god, work practice, this suggests that moderate sex life.If a kind of depressed, top-heavy, loss of appetite, dizziness phenomenon, such as palpitate to explain some excessive, should be moderated.There are a few of the sexually active couples, have been frequent intercourse, and the two sides are still fat, energetic, should also be considered to be appropriate.Second, the sex harmonyTo have a harmonious sexual life, both husband and wife should know the basic knowledge of sex, especially understanding the normal sexual difference.Otherwise, the husband and wife can't understanding each other.Sum up, men's and women's sexual function has some differences as follows:(1) male sexual desire is strong, strong, can cause sexual excitement;Women's sexual desire are relatively weak, sexual excitement and menstrual cycle (generally at the early stage of the ovulation and menstruation sexual desire is higher).There are a few women in premarital sexual weak or no, in the process of sex life after marriage, sexual desire to increase gradually.(2) the male sexual impulse is faster, into pleasure orgasm quickly, also lust fade faster, generally speaking, the normal men from sex to ejaculation, takes about 2 ~ 6 minutes (or 3 ~ 15 minutes).Female sex drive slower, general 10 ~ 30 minutes (or 5 ~ 15 minutes) to achieve a pleasure orgasm, orgasm to maintain for a long time, sexual desire fade is slower.(3) male sexual desire is easy to focus on the genitals, sexual desire is very high;More extensive and complex female sexual performance, including deficient, tenderness and caress, etc., to achieve a certain excitement, only have intercourse requirements.Both reaching orgasm at the same time is the most ideal sex or let her first orgasm, the male ejaculation.The woman does not affect sexual intercourse after orgasm continue;Moreover, is very different women and men can be reproduced in a short time pleasure orgasm (the degree of sexual pleasure because of the person different. The same person, every time also different degree of sexual pleasure).Third, sexual intercourseEach sex the most appropriate time, preferably at night before sleep, to rest and recover after sexual intercourse.Man heavier work in the day, and sometimes the body has feeling fatigue, it's best to sleep for a while again sexual intercourse, lest prone to leakage of pure premature phenomenon.In addition, in several cases, the man or the woman has to refrain from sexual desire, to reduce or avoid sexual intercourse.1.
