WHAT IS ARTIFICIAL FERTILITY?(εξωσωματικη)
It is the arrangement of techniques situated to get the origination in an artificial manner.
When the origination is done inside the lady's creature, it is designated "intracorporeal fertilization"; when performed outside of it, of "extracorporeal fertilization." The techniques of intracorporeal fertilization are: artificial insemination, GIFT, LTOT: extracorporeal fertilization techniques comprise basically of IVF with consequent incipient organism transfer (FIVET). Artificial insemination shows a technique went for acquiring an origination through the transfer to the female genital tract of male sperm, contingent upon the source of the semen:
- homologous artificial insemination, if the sperm originates from the husband or the accomplice:
- heterologous artificial insemination, if the sperm originates from a contributor other than the husband or accomplice.
Homologous artificial insemination is shown in certain types of female and male sterility, yet in addition in the theory of a preselection of sex, so as to maintain a strategic distance from, for instance, the transmission of specific hereditary infections connected to sex. The heterologous artificial insemination guesses the presentation of a third subject in the relationship of couple and makes serious problems in what alludes to the methodology of extraction and selection of the semen of the contributor and to the attribution of paternity.
GIFT is a technique of artificial intracorporeal fertilization that includes the synchronous transfer, yet separately, of the male and female gametes inside the fallopian tube; this technique is demonstrated in certain types of male or female sterility that can not be treated with artificial insemination, with the condition that the lady has at any rate one trunk open. The LTOT is a technique of artificial intracorporeal fertilization and includes the transfer of the oocytes taken from the lady herself to the fallopian container of the uterus: fertilization is then done normally. This technique is shown in instances of female infertility. Under the name "in vitro fertilization" (IVF), a technique went for acquiring an origination through the in vitro experience of the male and female gametes is demonstrated: the incipient organism got along these lines is then transferred to the female uterus. In vitro fertilization can be homologous (if the accomplice's gametes are used) or heterologous. FIVET is shown at times of male or female sterility.
Among the signs of this technique is the moderate male factor or when ovulation is undermined (anovulation or sporadic cycles). Obviously, in any event there should be a porous cylinder, or that the sterility time isn't extremely long.
In spite of the fact that it is possible to play out the insemination in the normal cycle of the lady, to expand the odds of progress it is common to invigorate the ovaries in a delicate manner to affirm the development of at any rate 1, 2 or even 3 follicles. That is the reason all the treatment is constrained by ultrasound, which will enable us to realize when to plan the insemination. All things considered, the odds of achievement of this technique are around 15-20% in each endeavor. When the pregnancy is accomplished, the likelihood of numerous pregnancy is 15%.
Upon the arrival of the insemination, the spouse conveys a semen test in the research center 1 or 2 hours before the insemination, which is processed to recuperate the versatile sperm and concentrate them in a little volume. In this manner, by utilizing a cannula, they are kept in the uterus, in this way maintaining a strategic distance from the long voyage that they ought to normally make from the vagina to the cylinder, where ovum-sperm fertilization happens. The process is effortless, and happens in merely minutes. The patient is released with the sign of taking progesterone to improve the risks of accomplishment, until the finishing of the pregnancy test, which should be certain, should keep taking.(εξωσωματικη γονιμοποιηση)
At a minimum, there must be at any rate 2-3 million sperm cells with dynamic portability for insemination. However, in the event that after 3-4 cycles of insemination pregnancy isn't accomplished, the likelihood of accomplishing pregnancy through this technique falls measurably and along these lines it is fitting to go to in vitro fertilization.
