What is Assisted Reproduction?
Assisted reproduction treatments are offered to improve the probability of pregnancy in couples with some pathology that diminishes their fertility, or after several months of trying unsuccessfully to conceive. Treatments are also offered to women without a male partner wishing for a pregnancy. Briefly, the treatments offered are:
The aim of ovarian stimulation is to achieve a correct ovulation. It is indicated in PCOS patients (Polycystic ovarian syndrome)or with irregular ovulation. With this treatment, 80% of the patients return to a normal menstrual rhythm.
Artificial insemination is a simple treatment of assisted reproduction where the woman’s ovulation is stimulated and synchronized with the entry of sperm into the uterus.
It is recommended when the time of sterility is less than 2 years, to women under 38, and/or when there is a mild male factor. It is also the treatment of choice for women without a male partner using donor´s sperm.
In Vitro Fertilization (IVF)
IVF is the most complex assisted reproduction treatment. It consists of stimulating the ovaries, extracting the oocytes and inseminating them with the partner’s sperm (or donor´s sperm) in the laboratory. One or two of the resulting embryos are placed into the uterus to obtain a pregnancy.
IVF is recommended in women over 38, when there is a prolonged sterility, or the diagnosis of the couple includes endometriosis, blocked fallopian tubes or moderate or severe male factor.
Egg donation is an IVF treatment where oocytes from a donor are inseminated with the sperm of the recipient´s partner (or from a sperm donor). One or two embryos are transferred into the uterus of the recipient.
It is mainly indicated in women older than 42, women with few oocytes and/or poor quality oocytes or when pregnancy has not been achieved after several attempts of IVF.
Embryo donation is the procedure whereby one or two donated frozen embryos are transferred into the uterus of a recipient. Donated embryos come from couples, that after the completion of an IVF cycle and having achieved a pregnancy, decide to donate the extra frozen embryos anonymously.
It is indicated in couples with repeated IVF failures and/or oocyte donation associated with poor embryo quality, and in women without a male partner.
