In vitro fertilization: assisted reproduction technique This infertility treatment is the third step in the assisted reproduction techniques ladder. This treatment brings the best pregnancy rate. Also called in vitro insemination, this technique is performed in assisted reproduction centers due to its high complexity. Indications for in vitro fertilization Couples that didn’t succeed with 4 intrauterine insemination cycles. Woman with obstructed Fallopian tubes. Moderate or severe decrease in the number and motility of sperm. When men have had a vasectomy in the past. In vitro fertilization consists in impregnating the eggs with the sperm in the lab, in order to obtain embryo that will after, be placed inside the uterus. This technique exists since 1978 when, Louise Brown, first baby to be conceived by this technique, was born in England. Through all these years, this method has improved and is used nowadays in thousands of clinics around the world. When first starting with this technique, the question of affecting the development or growth of the child was a big issue. After some decades, today we know that the use of this technique does not affect the child. 5 million babies have been born through in vitro fertilization since 1978. The objective of this technique is to ensure the impregnation of the egg by the sperm, correcting any factor causing infertility both in the male or female companion. In this technique, both male companion or donor semen can be used. In vitro fertilization procedure The in vitro fertilization procedure has 5 steps: Ovarian stimulation It consists in stimulating the ovaries with oral or injected medicines, making them produce one or two eggs. This stimulation lasts between 8 and 14 days. It is very important to have ultrasounds every 3 or 4 days to control – adjunting the dosis – the number and growth of eggs that are being developed. When it is observed through ultrasound that the folicules reached the right size, this indicates the prefect moment to make them ovulate through an injection. The doctor will indicate the exact moment when the medicine to ovulate should be applied, having the extraction of the eggs done 36 hours before the ovulation. This control should be done by specialists, through vaginal ultrasound, in order to avoid any complication such as a multiple pregnancy or ovaric hyperstimulation syndrome. Show more Semen preparation in the lab The day of the eggs extraction, just a few hours before the procedure, the semen sample is prepared. This sample is capacitated in the andrology lab to select the best sperm. Once selected, they are prepared to impregnate the egg. Ovarian punction: egg extraction Before the ovulation happens, the eggs are extracted and placed in culture media inside special incubators in the embriology lab. The extraction is performed with a needle that is introduced in the vagina with the help of an ultrasound. This step is known as ovarian punction. This procedure lasts about 20 minutes and a light sedative is used in order to ease the pain. It is not necessary any incision so, there will be no scar. After the punction, the patient remains at ease for some hours, waiting for the effects of the sedative to go away. The patient can go home righ after. Insemination of the eggs and embryo culture Once we have the sperm and eggs, the impregnation is done in the embriology lab. This can be done in 2 ways: Conventional in vitro fertilization: in a drop of culture media, some capacitated sperm is placed together with the egg. This way, the Intracytoplasmic sperm injection joins the egg to fertilize it. Sperm Intracytoplasmic sperm injection: with the help of pipettes and an special microscope, one sperm is chosen and injected directly inside the egg After, the inseminated eggs are placed inside incubators and left in the culture during 19 hours, when then they are observed to know if they are fertilized or not. Embryo transfer After 3 or 5 days in culture media, the embryo are transfered inside the uterus. This is a procedure that does not need anesthesia, lasts a couple of minutes and the disconfort is similar to that of a Pap test. 15 days later, a pregnancy test is done.

Egg donation: assisted reproduction technique This infertility treatment is the last step in the assisted reproduction techniques ladder. There are a lot of women whose fertility problem is the lack of egg reserve or, the low quality of the eggs. For these cases, the only possibility of reaching the dream of having a baby is through egg donation. To perform this technique, it is necessary to have an in vitro fertilization in an assisted reproduction center. This center should have an egg donation program. Candidates for egg donation: Aged women After trying 3 cycles of in vitro fertilization Women with ovarian failure, menopause or ovarian surgery Repeat abortions Women with low quality eggs Genetic and chromosomal abnormalities In vitro fertilization with egg donation is the fertilization of the donor’s eggs with the father’s sperm, in order to obtain embryos that will be transferred to the mother’s uterus. This technique has allowed thousands of couples to reach the dream of having a family. There are lot of doubts and, in some cases, even rejection from couples around the eggs donation technique; this is totally normal. As the couples get to know the details and other couple’s experiences, their perspective changes. The couples that decide to try this technique feel very grateful of having had this option to conceive a child. Show more Choosing the egg donor The egg donation is totally anonymous. The objective of the selection is to find a donor with similar physical characteristics to the mother. The donors are young and healthy women with no fertility problems. They are subject of medical, gynecologic and psychological tests in order to discard any sickness. Blood tests and, if necessary, genetic tests are performed to minimize the risk of any infectious or hereditary sicknesses. In vitro fertilization procedure with egg donation The in vitro fertilization with egg donation procedure involves 6 main stages: Endometrial preparation of the receptor Some days after the patient’s period, she will start taking medication orally or through patches. She will go for check ups every 5 to 7 days so, through an ultrasound, we can confirm that the endometrium is developing properly, in order to receive the embryo that she will have transferred. Ovarian stimulation of the donor It consists in stimulating the donor’s ovaries with oral or injected medicines, so she can produce a good number of eggs. When it is observed through ultrasound that the follicles reach the right size, this is the moment when they are ready to ovulate with an injection. The doctor will indicate this exact moment. The eggs extraction will be done 36 hours later, just before ovulation. It is important to synchronize the timing of the endometrial preparation of the receptor and the donor’s stimulation. Show more Laboratoy Sperm preparation The day of the donor’s egg extraction, just a few hours before the procedure, the father’s semen sample is prepared. This sample is prepared in the andrology lab in order to select the best sperm. Once selected, they are prepared to fertilize the egg. Egg ultrasound-guided aspiration: donor’s eggs extraction Before the ovulation, the donor’s eggs are extracted and placed in a culture media inside special incubators in the embryology lab. Eggs fertilization and embryo culture Once the father’s sperm and the donor’s eggs are ready, the fertilization is done in the embryology lab. The fertilization can be done in 2 ways: Conventional in vitro fertilization: in a drop of culture media, the selected sperm and eggs are placed together. The fertilization should happen naturally. Intracitoplasmatic sperm injection: with the help of micro pipettes and a special microscope, an individual sperm is injected into each individual egg. Show more Embryo transfer to the mother After 3 to 5 days in the culture media, the embryos are transferred inside the mother’s uterus. This procedure doesn’t need anesthesia, lasts a couple of minutes and the discomfort is similar to the one of a Pap test. 15 days later, a pregnancy test is performed. The embryos that are not transferred are vitrified (frozen) to preserve them for later use, reducing the need for additional IVF treatment cycles. Show more

Infertilidad: problema común y generalizado que ha ido en aumento La infertilidad es un problema muy común que afecta a millones de personas. Se estima que 2 de cada 10 parejas en edad reproductiva padecen infertilidad. Esto supone que, a nivel mundial, hay entre 50 a 80 millones de personas con este problema. La infertilidad no respeta raza, estatus social, religión o nacionalidad. México no es la excepción. Se estima que en nuestro país afecta a más de un millón de personas. La infertilidad ha ido en aumento en los últimos tiempos debido a factores ambientales como: contaminación, cambios en el estilo de vida que producen estrés, así como el deseo de postergar el formar una familia. Anteriormente, se buscaba el embarazo entre los 20 y 30 años de edad de la mujer. Hoy en día, un gran número de mujeres desea terminar sus estudios y desarrollarse profesionalmente, por ello empiezan a pensar en el embarazo después de los 35 años. Es a esta edad precisamente, que la mujer comienza el declive de su reserva de óvulos hasta llegar a la menopausia. Así, la probabilidad de lograr un embarazo disminuye a partir de los 35 años de edad. Mostrar más La infertilidad está considerada como una enfermedad El ser humano tiene arraigado el instinto de procreación y de protección de la descendencia desde sus ancestros. El hecho de no poder tener hijos tiene un impacto emocional bastante importante para algunas parejas que sufren infertilidad; pudiendo llegar a afectar su estado de salud, las relaciones sociales con su pareja, su familia o su trabajo. Por lo anterior, la Organización Mundial de la Salud considera la Infertilidad como una enfermedad. Debido a su impacto y al número de personas que la padecen, en algunos países llega a representar un importante problema de salud. Definición de Infertilidad: ¿Cuándo se considera que hay infertilidad? La organización mundial de la salud y las distintas sociedades de especialistas de reproducción coinciden en definir la infertilidad como: “incapacidad de lograr un embarazo clínico después de 12 meses o más de relaciones sexuales regulares sin protección”. Consideraciones importantes: Se consideran 12 meses ya que, la tasa de embarazo en parejas que no tienen ningún problema de infertilidad es del 10 al 20% por mes. Según varios estudios realizados con gran número de parejas, el 100% de las parejas sin problemas de infertilidad logran el embarazo en los 12 primeros meses. Para más información sobre cuándo tratar la infertilidad, pulsa aquí: más información. Se puede considerar como relaciones sexuales regulares a 2 coitos por semana. Mostrar más Efecto de la edad en la fertilidad de la mujer Desde que nace, la mujer tiene un número determinado de óvulos que, mes con mes se van desarrollando y preparando para ser ovulados y poder, en su caso, ser fecundados. Conforme pasan los años y con cada ciclo menstrual, la reserva de óvulos en los ovarios va disminuyendo, haciéndose más evidente a partir de los 35 años, momento en el que empieza a declinar hasta llegar a agotarse y empezar la menopausia. Las células precursoras de los óvulos tienen la peculiaridad, a diferencia de los espermatozoides en el hombre, de no regenerarse ni dividirse produciendo nuevos óvulos. Así, una mujer de 39 años tendrá óvulos también de 39 años de edad. Por esto, los hombres pueden tener hijos a edades más avanzadas que la mujer. A mayor edad de la mujer, mayor probabilidad de que sus óvulos tengan algún problema causado por esa edad, causando así, un problema de infertilidad. Estos problemas ocurren principalmente en mujeres mayores de 40 años.

Andrology lab This is where the semen is received and prepared for study to be used later for assisted reproduction treatments. This lab is key in an assisted reproduction center as it is only used to handle the semen sample. The difference with conventional labs where other samples are handled: blood, fluids, bacteria culture, etc. is that the andrology lab has the environment that protects the sperm from any contamination or affectation. It is essential to go to an andrology lab for the sperm tests, avoiding the conventional labs. In FiVER, we have an andrology lab fully equipped for the assisted reproduction treatments and for the cryopreservation of the sperm. Sperm studies The sperm studies are key for the infertility diagnosis. As 40% of cases are due to masculine causes, these sperm studies become essential. Sperm in urinalysis The urinalysis study allows us to detect if retrograde ejaculation exists. This problem appears when, at the time of ejaculating, the semen goes to the urine instead of going out. This can happen to diabetic patients or patients with neurological problems. This study will allow us to detect this problem and, if needed, use the sperm found in the urine. Sperm preparation Is the preparation of the sperm that will be used in the intrauterine inseminations or in vitro fertilizations. With this method, the seminal liquid is eliminated; the sperm with motility is chosen and prepared to fertilize the egg. Sperm retrieval When a man has little to no sperm in his ejaculate, it may be possible to retrieve sperm from his testicles or epididymis. This is a procedure performed by an urologist. The sperm retrieved can either be frozen for future use or used immediately for an in vitro fertilization cycle. This is the solution for the vasectomy cases. The sperm retrieval is a simple procedure, with local anesthesia and lasts only some minutes. Sperm freezing The sperm freezing allows it to live during years and be used after. The freezing is used in patients that will be subject of testicule or prostate surgery, chemotherapy or radiotherapy due to testicular cancer. This way, these patients can preserve their healthy sperm so, in the future, have a child with the support of assisted reproduction techniques. The freezing is also used in patients that, for some reason, are separated from their couples for long periods of time. This way, intrauterine insemination is possible without the physical presence of the father. Besides freezing the semen, also testicular tissue samples obtained through testicular biopsy are frozen. Semen bank Lot of cases of infertility are due to men not producing sperm. In these cases, a semen sample can be used. This option is also used for women with no male companion that wish to have a baby. The semen bank is formed by young healthy samples that have been through strict medical studies, lab, psicological and genetic studies so any hereditary, infectious or chromosomal disease is discarded. In FiVER, all our donors are closely studied, following strict international standards and all samples have a quarantine period of 6 months before using them. Semen donation is anonymous. It is recommended to choose the donor according to the physical characteristics of the future father.
