Are college students pregnant? Of course, the proportion is still very small. If you get pregnant unexpectedly, if you don't want it, you can take the following measures:
First, curettage technology:
As long as abortion is mentioned, people will naturally think of curettage, so curettage has almost become synonymous with induced abortion. This is also the case. Curettage is the most commonly used method of early induced abortion. Although curettage does not require surgery, it is also a gynecological operation and must be carried out under strict disinfection. The operation is divided into two steps. The first step is to expand the cervix sufficiently, and the second step is to put a curette into the uterine cavity and scrape off the embryo. The longer the pregnancy, the bigger the fetus will be. At this time, you need to expand the cervix to the maximum to scrape the fetus, so it is more difficult to scrape the uterus. At the same time, the longer the pregnancy, the softer the uterus will become, and the chance of puncturing the uterus during surgery will naturally increase. Therefore, it is generally only within three months of pregnancy that the fetus can be scraped out by curettage, and curettage surgery should not be used after three months.
Second, the surgical abortion:
If you are pregnant for more than three months and it is not suitable to continue pregnancy due to special reasons such as health, another operation should be adopted to take out the fetus. You can cut the uterus after laparotomy to take out the fetus, or you can cut the cervix or uterine isthmus from the vagina to take out the fetus.
Third, drug abortion:
Taking some medicine to shoot down the fetus is the most ideal method, but there is no such good medicine at present. Some women secretly eat a lot of quinine when they think it can be aborted. In fact, quinine can't achieve the goal of abortion, but it will ruin their health and even cause some defects in the fetus.
Fourth, abortion with inducer.
The physical examination of the prospective father is mainly a specialized examination of male genitourinary system, including the physical examination of penis, foreskin, testis, epididymis and spermatic cord. Generally, you can get a preliminary understanding of whether the external genitalia is developing normally, whether there are too long foreskin, too small testicles, varicocele, epididymal inflammation and so on through the doctor's "listening, listening and asking". Varicocele is currently recognized as the cause of male infertility, and its incidence rate is about 15% in normal people, while it is about 40% in male infertility patients. The incidence of small testis and cryptorchidism is not low. Some time ago, a young man who was about to get married came to the hospital for examination and found that his bilateral testicles were in a baby state and had no development at all. I haven't found it for so many years, which shows the importance of physical examination before marriage and pregnancy.
Semen examination is also the most important and direct examination about fertility. Abstinence is usually required 2-7 days before semen examination. Too short or too long abstinence time may lead to inaccurate results. Routine examination of semen includes semen volume, pH value, liquefaction state, sperm quantity, motility and sperm morphology. The decrease of sperm number, sperm motility and sperm deformity rate may lead to male infertility. Semen can also be used to check whether there are mycoplasma, chlamydia and gonococcal infections in male reproductive tract, because these infections can lead to infertility or embryo abortion. If the semen is abnormal, it is generally necessary to recheck 1-2 times. With the aggravation of environmental pollution and the increasing pressure of social life, the semen quality of modern men has a downward trend. The reference values of sperm quantity and motility in the fifth edition of the World Health Organization's Laboratory Manual for Human Semen Testing and Processing have been lowered, which indirectly explains this trend. For people who have been exposed to radiation, high temperature and chemical products for a long time, the quality of semen may be affected.
