Embryo Donation
Relevant information about Embryo Donation .It is implemented when both members of the couple do not produce fecund gametes. The purpose is to originate embryos from gametes donated voluntarily by a healthy and fertile person, who has been previously evaluated from the psycho-physical and genetic point of view. The procedure consists in, once embryo is develop enough and specialist does not considerate it in risk, introduce it in the receptor´s uterus. In vitro fertilization technique often results in a number of frozen, unused embryos after the woman for whom they were originally created has successfully carried one or more pregnancies to term. In embryo donation, these extra embryos are given to other couples or women for transfer with the goal of producing a successful pregnancy. The resulting child is considered the child of the woman who carries it and gives birth, and not the child of the donor, the same as occurs with egg donation or sperm donation. Embryo Donation is chosen by many couples who are unable to afford conventional reproductive treatments or who have been unsuccessful with in vitro fertilization treatments.
The difficulties to conceive could come from the man, from the woman or from both of the couple´s member. Between the 30% and 40% of the cases of infertility or inability to conceive (fecundity) are due to the “masculine factor”; between 40% and 50% is attributed to female anomalies, and the remaining percentage is attributed to both members, or strangers causes. There are many reasons and anomalies that might causes inability to conceive; including the emotional or psychical types. The principal reasons of inability to conceive in men are related to premature ejaculation, impotence, deficiency of hormones, environmental pollution, scars due to sexually transmitted diseases, decrease of the number of sperms cause the consume of marijuana, or to the use of some prescribed drugs, radiation or influence of chemical substances over the testicles, endocrine alterations, etc. In case of the women, some of the most frequent physical reasons are scars due to a disease of sexual transmission, malfunctions in the ovulation, insufficient nutrition, hormonal imbalances, cystitis, ovary or uterus tumor, pelvic tumors, past infections or to a deficient communication between the cervix channel and the Fallopian tubes. Stress is being studied as factor of infertility, especially in men; though its grade of incident has not been decided yet.
The procedures of Embryo Donation are basically two. Frozen Embryo Donation involves using frozen embryos donated by another infertile couple. Many couples go through IVF treatments in order to get pregnant. Despite the fact that nearly twelve embryos are created for each IVF treatment, only three of these embryos are ever implanted. Many couples choose to donate their remaining frozen embryos to couples who are having trouble conceiving. Embryos can be cryo-preserved several times after fertilization, ranging from one day after fertilization up to five or six days after. Embryo cryopreservation allows embryos to be kept healthy and viable for up to ten years. Once an embryo is choose, it is unfrozen and prepared to reinitiate its development. The second method is embryo creation. This procedure involves using a donated egg and a donated sperm to create an embryo. This embryo will not be biologically related to patient. The resulting embryo is then transferred into patient´s uterus. The procedure of creation is in vitro fertilization type.
The patient will have to remain for a couple of hours in the position recommended by the specialist once finished the procedure. Then, as soon as the patient was checked and the development of the embryo was controlled, she could return home. The patient might be supplied with medicinal injections that stimulate her uterus for the correct receipt and acceptance of the embryo. These medicinal injections could be continued by the patient by herself, if the specialist advises it. Medications and vaginal protectors are also provided to the patient. Though a few days after procedure patient could realize the activities commonly allowed to a pregnant woman, it is advised to patient to rest for at least a week.
No big complications might appear during the transfer procedure. There can occasionally be difficulties in passing the embryo transfer catheter through the cervix (due to a bad preparation procedure, or due to the patient had never been a mother before). In extreme cases, specialist may decide that it is in your best interests to delay the embryo transfer and freeze all suitable embryos until after the cervix has been stretched. Multiple embryos transfer has more risk chances that single one.
The embryo donation procedure allows unfertile couples to conceive a baby. This types of procedure benefits couples that look for a natural pregnancy process. Only the first step of the pregnancy is artificial. Although its evolution will be monitored for the whole 9 months, the rest steps are the common ones to healthy couples. But as in any recently-develop-procedure, there might be secondary or unwanted effects. Apart of the total failure of the procedure (embryo death or uterus rejection), multiple pregnancies could happen.
