Chance is a deciding factor in our lives. Where we are born, our society and available resources determine our access to the coverage of basic needs such as health care and education. Specifically, limited access to health services or gynecological health affects millions of women and girls all over the world differently depending on where they live. […]
This is not science fiction, it’s reality. It is reproductive medicine and advanced genetics together to achieve healthy children who are free of diseases. Before, medicine focused on a person’s health. Now thanks to genetics and scientific research we are able to go one step further and take care of the embryo. […]
Currently there are two main techniques used to achieve Assisted Reproduction IVF. These two techniques are conventional in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI). […]
Endometrial polyps are protrusions or growths in the endometrium, the lining of the uterus. Contain abundant inside your blood vessels and endometrial glands that respond to hormonal stimuli.
Polyps proliferate to form a region of the basal layer of the endometrium, and are less responsiveness to hormonal changes. Taking place repetition of menses, the endometrium functional layer surrounding the polyp breaks off and becomes increasingly individual from a pedicle. […]
Couples that don’t achieve pregnancy after in vitro fertilization treatments and those who lose their pregnancy in early stages require a multidisciplinary approach in order to diagnose and treat their reproductive problem.
From a genetic point of view, these patients are more likely to produce embryos with chromosomal abnormalities. To improve these couples’ pregnancy rates, the preimplantational genetic diagnosis (PGD) can be applied. In these cases, the goal is to select the embryos with the highest capacity of resulting in an ongoing pregnancy thanks to the fact that the PGD allows us to identify the number of chromosomes in the embryo. Only embryos with the correct number of chromosomes can lead to a healthy child, others will arrest in their development or will lead to a miscarriage. […]
When one starts an in vitro fertilisation (IVF) treatment, one of the most frequent concerns is the number of high quality embryos that can be obtained.
This number is variable and depends on several factors such as the ovarian reserve and gamete quality (egg and sperm). Once the eggs are fertilised, they are considered embryos, which begins after their early division. The embryo division is observed in the IVF laboratory on a daily basis and is key information to determine the embryo quality. The Spanish Association of Reproductive Biology (ASEBIR) establishes a classification according to various observed morphological parameters, which indicate the embryo quality according to their capacity to implant in the womb. […]
Reproduction treatments with donated eggs have gained significant importance in recent years.
It is worth noting the main characteristics that the Law 14/2006 on assisted human reproduction techniques states on egg donation, which are explained below: […]
Scientific evidence from the last 15 years shows that without a doubt, environmental toxins before conception and during pregnancy cause long-lasting effects on reproductive health. An example of this is the exposure to mercury, which causes cognitive impairment in children. Another example is the exposure to agricultural pesticides, which is associated with sperm quality alterations and higher incidence of testicular and prostate cancer for men, and in women it interferes with the development of puberty, ovulation, fertility and menopause. […]
Without a doubt, one of the most emotionally stressful stages a patient undergoing IVF has to face is the period between the embryo transfer and the pregnancy test result.
It is a natural instinct for someone in this situation to want to do everything in her power to increase the chances of success, which is why she is extra sensitive to any messages she receives from family members, friends, the internet, etc. This leads to a confusing situation because oftentimes the advice received is contradictory. As if that weren’t enough, the vast majority is unfounded and not validated by any scientific evidence. Their question is often “should I rest or not?” […]
It is well known that having the best possible sperm quality is important to the success of assisted reproduction techniques. To achieve this, the lab has to improve sperm quality based on its motility and morphology, selecting the sperm that is considered to be the best.
However in every ejaculate sperm with abnormal membranes are found, which are programmed to “die”. This process is called apoptosis, or programmed cell death. Approximately 20% of sperm in subfertile patients are thought to be in the process of “celular death”. […]
