Frequent questions
The time of ovulation is the time for the meeting between the oocyte and the sperm to form an embryo. Considering a normal menstrual cycle of 28 days, this occurs towards the middle of the cycle, approximately day 14 (4 days before and 4 days after).
If your cycles are regular, ovulation usually occurs around the middle of your cycles. In general, it is accompanied by signs such as increased vaginal discharge, increased sexual desire, discomfort in the lower abdomen, although you may not notice any of them. We have the help of urine test strips that help us determine the moment of ovulation.
The endometrium is the innermost layer of the uterus, which prepares every month to receive an embryo. Endometriosis is one of the most common causes of infertility in women and consists of the presence of endometrium outside the uterus, such as in the ovary, fallopian tubes, or other areas of the abdomen and pelvis. Much is known about it but we still cannot explain exactly what its cause is and how it makes pregnancy difficult, whether it has a harmful effect on embryos, oocytes, or due to some immunological mechanism.
These types of eating disorders usually cause serious health problems, including gynecological and reproductive problems. For the hormones necessary for ovulation to be released, an amount of fatty tissue is needed in the body that women who suffer from bulimia or anorexia cannot maintain. That is why it is so important to take care of ourselves to be reproductively healthy women and think about our children long before planning to have them.
A woman’s fertile life ends when her ovulatory menstrual cycles end, this means that if she is 38 years old but still ovulates, she has a chance of getting pregnant. After the age of 35, reproductive capacity decreases as the oocytes begin to age, this makes it difficult but in no way prevents her from achieving pregnancy; Although it is important that she does not let too much time pass.
Yes, you can achieve this by receiving a donated egg. Nowadays, receiving a cell as special as an egg and then fertilizing it generates an embryo that, once placed in your uterus, if it achieves implantation and good development, will receive all of your immunogenetic imprinting. You will see it grow through ultrasounds and the exchange between you and the embryo will be so intense that once it is born and you breastfeed it, the decision to receive a donated egg will seem miraculous.
Frequently asked questions about egg donation
It is an assisted reproduction technique that consists of extracting eggs from a donor woman and selecting them under strict biosafety protocols to then fertilize them and generate embryos that will be implanted in the uterus of a recipient woman with the aim of achieving a pregnancy. This procedure helps those women who, due to health problems, cannot produce their own eggs (because they have serious alterations in their quality and/or genetic characteristics) and suffer from infertility.

It is a simple, outpatient procedure that is performed in 20 minutes, after which the donor leaves after 1 hour.
It is important to remember that, although each woman has a limited number of eggs from birth, these eggs are lost naturally with each cycle. Donating eggs does not imply an advance of her own menopause, it is a safe procedure for the health and future fertility of the donor. It has been proven for more than 30 years.

The goal is to create the right nest This takes between 14 and 21 days and you will only have to come a couple of times to check it with ultrasounds. When the endometrium is in good condition and we already have the eggs, we request the sperm sample that is prepared to fertilize them. As soon as we have the embryo (after three to 5 days) it is transferred into your uterus.
Frequently asked questions on embryo transfers
We meet you with a full bladder and take you to the CER operating room, which is next to the embryo laboratory. It is without anesthesia and you should not feel any discomfort. The embryologist loads a very delicate catheter with the embryo and hands it to the doctor who places it inside the uterine cavity. Everything is monitored sonographically
Then you are ready to leave with the rest of the medical instructions.
Our behavior is to avoid multiple pregnancies due to the risks they entail for both the mother and the fetus. For this reason, the vast majority of times we transfer only one embryo. In case of having surplus embryos, they are cryopreserved to be used in other cycles.
After 14 days and through blood testing of beta subunit of HCG (human chorionic gonadotropin)
Success rates are closely linked to adequate selection of the donor and experience in the medical management of the recipient.
These chances are above 50% per cycle and increase as the cycles are repeated.
IVF/ICSI FAQs
In women who have very damaged or absent fallopian tubes.
In those women who have made three or more attempts at intrauterine inseminations without achieving pregnancy.
In cases of severe endometriosis
In women with an ovarian reserve at the limit due to advanced age or another cause, to offer a technique with greater chances.

Given your history, age and hormonal dosages, I would suggest not insisting on IVF and thinking about the possibility of egg donation. Your chances of getting pregnant would go from 5% to 50% per attempt.
Both the epididymis and the testicle can have sperm and even precursors. These can be obtained by puncture or biopsy and after a period of search and incubation, the eggs can be microinjected (ICSI), generating embryos and pregnancy. The CER was the first center in Argentina that achieved pregnancies and live births by applying the MESA and TESA techniques.
Yes absolutely.
If other causes of fertilization failure are ruled out, it is advisable with this history to repeat the procedure and perform ICSI.
