1、 IVF technology
Test tube baby technology is one of the most common medical means in the elderly childbearing. Through in vitro fertilization and embryo transfer, it helps couples who are unable to conceive naturally realize their reproductive dreams. The specific process is as follows:
First, women receive hormone therapy to promote ovarian development and produce multiple follicles, and then use ultrasound guided fine needles to extract the eggs in the follicles. Subsequently, eggs and sperm are fertilized in vitro in the laboratory to form embryos. Finally, select the best quality embryos to transfer to the female uterus, hoping to be able to successfully implant and develop into a healthy fetus.
IVF technology has greatly improved the reproductive opportunities of elderly women, but there are also certain risks and restrictions. On the one hand, female age is an important factor that affects the success rate of IVF. With the increase of age, the success rate will gradually decrease; On the other hand, the cost of surgery is high, and the operation needs the support of high-tech hospitals and doctors.
2、 Artificial insemination technology
Artificial insemination is another commonly used medical method for the elderly. It increases the chance of pregnancy by injecting sperm directly into women's uterus. Artificial insemination can be divided into two forms: autogenous artificial insemination and allogenic artificial insemination.
Autologous artificial insemination is to extract the semen of the male spouse and inject it into the female uterus after special treatment. Allogeneic artificial insemination is the use of semen from donors into the uterus of women.
Artificial insemination technology is simpler than IVF technology, and it is a feasible choice for some couples who are not suitable for IVF. However, its success rate is relatively low, so many attempts are needed to increase the chance of pregnancy.
3、 Egg freezing technology
Egg freezing technology is one of the methods to prevent fertility problems for elderly women. With the growth of age, the quality and quantity of female eggs will gradually decline, and frozen eggs will be collected and preserved in advance through the collection of high-quality female eggs.
Before deciding to freeze eggs, women need to receive hormone treatment to promote the development of high-quality ovarian follicles. Then, the doctor collected the eggs through a fine needle guided by transvaginal ultrasound. After special treatment, the eggs were stored in liquid nitrogen and other frozen storage methods.
The egg freezing technology enables women to save high-quality eggs for future needs. However, it should be noted that although frozen eggs have improved the chances of elder childbearing, it does not represent success, and it still needs to be combined with other assisted technologies for assisted reproduction.
4、 Embryo screening and gene detection technology
Embryo screening and gene detection technology is a means of assisting the elderly to have children. Through genetic and morphological testing of embryos, couples can select healthy embryos for transplantation, reducing the risk of chromosome abnormalities and genetic diseases.
Embryo screening and gene detection technologies mainly include laser radiography, gene chip technology, PCR technology, etc. These techniques can detect genetics, chromosome structure, gene mutation and other aspects of embryos.
Embryo screening and gene detection technologies play an important role in the elderly childbearing, which can improve the success rate of embryo transfer, while avoiding the transmission of genetic diseases and chromosome abnormalities.
Summary
The medical means of elder childbearing mainly include test tube baby technology, artificial insemination technology, egg freezing technology, embryo screening and gene detection technology. The emergence of these technologies has provided more fertility opportunities for elderly couples and helped them realize their desire for late childbearing. However, the application of these technologies still needs the guidance of doctors and the reasonable choice of patients to ensure the safety and success rate of the birth process.
