In previous occasions we have addressed the issue of the influence of maternal obesity in the achievement and monitoring of pregnancy, but today we want to focus on what consequences may have for the child born, and the adult who will become, having been subjected to a pregnancy with excess BMI. An adult woman is considered obese if she has a body mass index greater than 30. According to the World Health Organization, 1400 million people over 20 were overweight in 2008, and of these, 200 million men and nearly 300 million women were obese. Cases of obesity have multiplied worldwide since 1980. Below you have an index with all the points that we will discuss in this article. Index 1. Risks 2. What do I do if I am obese or overweight? 3. Authors and collaborators Risks A recent study published in the British Medical Journal (BMJ) indicates that children of obese mothers are more at risk of dying prematurely as adults. According to the researchers, the risk of premature death ...

The GnRH analogs are used in the main assisted reproduction treatments such as IA, IVF and ICSI . They are drugs that are used in order to avoid early follicular luteinization and to control the time of ovulation so that it does not occur prematurely.

Description of a case with successful pregnancy in a 35-year-old patient with XY pure gonadal dysgenesis (Swyer's syndrome) and with chronic idiopathic hypertension that undergoes in vitro fertilization and embryo transfer . Karyotyping is performed due to primary amenorrhea , diagnosis is confirmed and subsequently, a gonadectomy is performed, hormone replacement therapy is administered and hypertension is investigated. The patient gets pregnant through an oocyte donation treatment and a live newborn by caesarean section. Below you have an index with all the points that we will discuss in this article. Index 1. What is Swyer's syndrome? 2. Description of the case 3. Discussion 4. Bibliography 5. Authors and collaborators What is Swyer's syndrome? Swyer's syndrome, also known as XY gonadal dysgenesis, was first described in 1955 by Swyer. They are tall patients with female external genitalia with a normal vagina, fallopian tubes, hypoplastic uterus...

Teratozoospermia refers to the bad morphology of sperm in the ejaculated semen of the male. These men have a lower seminal quality and, at times, suffer from infertility and difficulties in getting pregnant. The causes of teratozoospermia are unknown in most cases. However, we are going to discuss the possible alterations that these abnormal sperm cause in the semen. Below you have an index with all the points that we will discuss in this article. Index 1. Defects in spermatogenesis 2. Reversible teratospermia 2.1. Lifestyle 2.2. Semen infections 2.3. Drugs 3. Irreversible teratospermia 3.1. Cancer treatment 3.2. Genetic alterations 3.3. Related pathologies 4. Questions from users 4.1. Can live sperm have bad morphology? 4.2. Can leucospermia cause teratospermia and male sterility? 4.3. Are the causes of teratozoospermia and asthenozoospermia the same? 5. Recommended reading 6. Bibliography 7. Authors and collaborators Defects in spermatogenesis ...

New images allow us to see how the endometrium makes movements to keep the embryo inside the uterine cavity and prevent its expulsion, making it easier to implant in the most appropriate place. Below you have an index with all the points that we will discuss in this article. Index 1. Study of ultrasound 2. Results 3. Authors and collaborators Study of ultrasound The Institut Marquès presented the weekend at the Alpha Conference in London a video showing the activity of the uterus when receiving embryos after In Vitro Fertilization. The images show movements of the endometrium (the inner layer of the uterus) that allow embryos to be placed, regardless of the place where the gynecologist has deposited them. For the study, ultrasound images of 18 patients were recorded during and after the embryo transfer after in vitro fertilization. The videos were repeated every hour for four hours after the transfer. Dr. Marisa López-Teijón, Head of Assisted Reproduction of Institut Mar...

Teratozoospermia is a sperm disorder based on the bad morphology of sperm in the semen of a male. This causes male infertility by hindering the achievement of a natural pregnancy . The sperm can suffer malformations in its head, neck or tail, possibly due to some failure during its formation process ( spermatogenesis ). Below you have an index with all the points that we will discuss in this article. Index 1. Abnormal spermatozoa 2. Types of sperm deformation 2.1. Deformations in the head 2.2. Deformities in the neck 2.3. Deformations in the tail 3. Number of alterations 4. Questions from users 4.1. What kind of more frequent deformations exist in sperm? 4.2. Can abnormal sperm fertilize? 4.3. Are the abnormal double-headed sperm viable? 4.4. What is globozoospermia? 4.5. How is a pin-head sperm? 5. Recommended reading 6. Bibliography 7. Authors and collaborators Abnormal spermatozoa The World Health Organization (WHO) states that a sperm with pe...

In the study of infertility, tubal patency and correct uterine morphology are key parameters that should be studied in the first steps in the fertile study of the couple, in this case, of the woman. Below you have an index with all the points that we will discuss in this article. Index 1. What is the HSG? 2. Advantages of the virtual HSG 2.1. Studies 3. Authors and collaborators What is the HSG? The technique of hysterosalpingography (HSG) allows to rule out abnormalities of the cervix, such as lengthening, an excessive amplitude that can be related to a cervical incompetence; in the uterine cavity it allows to detect the position of the uterus, the possible presence of cysts, fibroids, adhesions, or some congenital alteration such as the uterus didelfo or septate. It is possible with this technique to detect even some types of ovarian tumors and even bone malformations such as spina bifida occulta. Obstructions in the tube prevent the sperm from reaching the mature ovum,...

Ultrasound is a diagnostic imaging technique based on the emission of ultrasound (sound waves at high frequency) by a probe. Below you have an index with all the points that we will discuss in this article. Index 1. What is an ultrasound? 2. Risks of fetal ultrasound 3. Types of ultrasound in pregnancy 4. First quarter 5. Second quarter 6. Third quarter 7. Authors and collaborators What is an ultrasound? Ultrasound penetrates the organ to be studied, in this case in the fetus, and through various physical phenomena such as reflection, a part of these ultrasound is transformed into electrical signals that appear on the screen of the ultrasound in the form of images. To facilitate the passage of ultrasound through the skin, an aqueous gel is used. Ultrasound during pregnancy The main ultrasounds are performed in weeks 12, 20 and 32 of pregnancy. Each of them is done in a different way since its purpose is different. It is possible that additional ultrasounds are perf...
