The assisted reproduction techniques

Infertility is a very common problem today faced by couples worldwide; there could be varied reasons a couple cannot conceive naturally. In serious cases of infertility, the medicines are futile and treatments have to be taken and each treatment varies from couple to couple. The fertility techniques are tried and tested treatments with laboratory procedures.

  1. The Intra Uterine Insemination IUI method includes preparing of seminal fluid in the laboratory. The semen washing is done here and later injected insAssisted reproductive technologyide the uterus. The ovaries are stimulated so to produce more eggs each cycle. This method is usually followed when the man has deficiency of sperms. The first ever such treatment was done in 18th century.
  2. The conventional in-vitro fertilization commonly termed as IVF, the first case of IVF was performed in 1978. It took nearly a century to research the IVF technology. The in vitro fertilization procedure includes fertilizing of eggs in the laboratory in a dish, the eggs are retrieved from ovaries and sperms are added to it and put in a dish after washing semen with special media. Then the dishes are put in incubators until the embryos are formed and later transferred to woman’s uterus. The eggs are mixed with thousands of sperms in a dish and kept in special incubators in natural conditions, after fertilization takes placed the embryos are injected in the uterus through a special catheter. The IVF is usually preferred by women having blocked fallopian tubs, seminal problems in man, ovulation problems, infertility, seminal anti-bodies in the body of the woman.
  3. The Intracytoplasmic sperm injection ICSI process includes the ovum injection with single sperm of a husband, the use of single needle is made to pass through the wall of egg and sperm is introduced in the cytoplasm of eggs. The chances of fertilization are checked on later and after the division happens, the embryos are passed inside the women’s uterus. The treatment is done in the cases of seminal fluid problem or deficiency in the number of sperms.
  4. The percutaneios Epididymal sperm aspiration PESA is performed in the case husband has absense of vas deferens, this is the organ from which sperm pass to seminal fluid through epididymis. Husband may also have past infections which leads to obstruction, there could also be problems for the men who had vasectomy and reversal failed.
  5. The Testicular sperm aspiration commonly called as TESA, in this process the sperm is obtained from testes by aspiring a needle or a surgical procedure. The extracted sperms are used for ICSI process. The procedure is usually followed if there is absence of sperms in epididymis or obstructed epididymis.
  6. The assisted hatching procedure is followed if there have been case of repeatitive implantation failure and also in the case where the wall of embroyo is thick. The method makes a small hole in the wall of embryo using needle or a laser beam, this increases the chances of implantation.
  7. The excessive embryos are frozen and stored for future embryo transfer, in this case women need not go through ovarian stimulation. The success of this method highly depends on the quality of embryos.
  8. The oocyte freezing is not as much successful at this point, the research for this method to be successful is still on.
  9. Freezing seminal fluid is followed in the cases where men are unable to give a sample on the eggs retrieval day, when men has no sperm in his seminal fluid, the men with decreased sperm proportion, men having testicular disease, men having cancer.

Any procedure you follow might be successful at just one go and in some cases it is possible to select the sex of the baby by performing cell biopsy from embryo itself, the biopsy test are also done to select and detect the healthy desired embryos.
