When talking about fertility treatments some medical terms that are unknown to women who want to have children and need help to become mothers are often used, they are part of a technical glossary. From Women's we have thought of offering you this Dictionary of Fertility to facilitate the understanding of the contents related to the disease. The excellence of our team, with the presence of Dr. Dexeus as the founder of the clinic, a world authority on fertility allows us to provide a first class service to all women in this field.
It is the name given to the chromosomes that are not sexual, it is also called the somatic chromosome.
In humans, the chromosomes from pair 1 to 22 are all autosomes. Sex chromosomes are pair 23 and are called heterochromosomes or gonosomes.
Absence of sperm in the semen. There are two types, obstructive and secretory.
La secretory or non-obstructive It is the most frequent manifestation, the testicles do not produce sperm or do so in a minimal quantity. The other type of azoospermia is obstructive, an obstruction prevents the sperm produced in the testicles from joining the rest of the fluids that make up the semen, which is what happens in vasectomy.
Bacilli of Doderlein
Name given to non-pathogenic bacterial flora whose origin is the vagina. They maintain the acidic environment of the vagina.
Embryo in a very advanced stage of development. Between 5-6 days after fertilization. Cell differentiation begins and the chances of pregnancy increase considerably.
Process by which the uterus is ready for gestation. It produces a series of physiological changes in women that last from the first day of menstruation until the first day of the next cycle.
Name given to the ovum fertilized by a sperm with the genetic material necessary to create a baby.
It is a duct formed by 2 arteries and a vein, wrapped in a gelatinous substance that, in addition to serving as a union between the placenta and the navel of the fetus embryo, has the property of multiplying, generating the cells that the blood contains.
It is the procedure used to preserve sperm, eggs and embryos through freezing. Storage occurs in liquid nitrogen at 196 degrees or in vapor tanks, also nitrogen.
It is the period that passes between fertilization and delivery. Its duration is approximately 9 months.
Acronym for Preimplantation Genetic Diagnosis. It allows detecting genetic abnormalities in an embryo before being transferred to the woman's uterus. In this way, the possibility of having healthy offspring free of genetic diseases is maximized. View source
These are the days when the woman has already ovulated and has the best chance of pregnancy. In this process, the ovary releases an egg that descends through the fallopian tubes to be fertilized by male sperm. The most fertile days are those in the middle of the cycle, that is, 14-15 days after menstruation.
It is the pregnancy that occurs outside the woman's uterus. The embryo implants in the fallopian tubes, ovaries, or abdominal cavity. They pose a risk to the mother. The fetus can never develop outside the uterus.
An egg that has already been fertilized.
Benign disease that affects women during their reproductive life, when the endometrium is located outside the uterus and therefore develops abnormally. It causes pelvic pain, swelling, scarring and difficulties conceiving.
Process by which a sperm enters the interior of the ovule, joining its genetic material and forming an embryo.
Acronym for In Vitro Fertilization, a fertility treatment....
La in vitro fertilization is an assisted reproductive treatment through which they are joined in a laboratory (hence the name of vitro) an egg and a sperm giving rise to embryos, which are cultured for a few days. The objective is that these embryos are of good quality to be implanted in the mother's uterus, giving rise to a pregnancy. One of them will be implanted and the rest will undergo a process of cryopreservation to discuss them in case you need to use them later.
IVF with natural cycle
An IVF procedure in which one or two eggs are obtained during a spontaneous cycle without the use of hormonal medications.
Acronyms in English that refer to follicle stimulating hormone, follicle stimulating hormone or follitropin. It is secreted by the pituitary gland. It is very important in the reproduction process as it controls the maturation of the gametes (eggs and sperm).
They are the two reproductive cells, sperm and ovum, which have a haploid number of chromosomes that, when combined, form the zygote, giving way to gestation.
Sexually transmitted disease (STD) caused by the bacteria Neisseria gonorrhea. It can be a cause of infertility among other complications.
Hormone produced by small follicles in the ovaries.
The antimüllerian hormone (AMH) is used as a marker to know the number of ovarian follicles of the woman since it is a proportional indicator of the number of available eggs that the woman has. If a low ovarian reserve is detected, action must be taken.
LH is produced in the pituitary gland and is relevant in sexual development and functioning. In women, it helps control the menstrual cycle and causes the ovum to be released from the ovary, which is known as ovulation....
Why is a luteinizing hormone (LH) level test done?
Since LH levels rise rapidly just before ovulation, the test allows us to know if this physiological process will occur soon.
Abbreviation for Artificial Insemination, a technique related to fertility or assisted reproduction treatments.
Acronym for Conjugal Artificial Insemination. It is an artificial insemination technique with semen from the woman's partner. Sperm are selected and inserted into the uterus.
Acronym for Intracytoplasmic Sperm Microinjection. Technique used in cases of male infertility to enable fertilization of the ovum....
Using this technique, a sperm is extracted from a testicular semen sample to select the most suitable sperm to fertilize the egg.
Process that allows the embryo to anchor itself to the endometrium. Without this process there is no pregnancy. From that moment, the placenta begins to form, which will be the protection and sustenance of the future baby.
Intrauterine insemination (IUI)
An ART in which sperm are placed into the patient's uterus through the vagina and neck, with the help of a cannula.
Intracytoplasmic Injection (ICSI)
A variation of IVF in which a sperm is injected into an egg to ensure fertilization.
The pandemic drives fertilization treatments to preserve fertility
Dr. Jan Tesarik, scientific advisor and speaker at the Virtual Global Summit on Covid-19, has indicated that the current pandemic has promoted fertility treatments. lavanguardia.com Date: 03-08-2020
Sperm compete to fertilize eggs
For the first time, it has been experimentally shown that sperm with the t haplotype advance faster than their "normal" peers and therefore have an advantage in fertilization. The researchers analyzed individual sperm and revealed that most cells that progressed poorly in their trajectories were genetically "normal," while straight-moving sperm mostly contained the t-haplotype.

Acronym for Magnetic Activated Cell Sorting. A technique for selecting the best sperm that can be used for male infertility assisted reproduction. Improves the fertilization rate around 12-14%.
Process by which eggs and sperm are formed in organisms that reproduce sexually....
Cells in the body have two sets of chromosomes, one from the father and one from the mother. These cells are called diploids. On the other hand, when an egg or sperm is generated, it should only have a single set of chromosomes and then combine with each other. These types of cells are called haploid.
Process through which, at an early age, there is a decrease in the reproductive capacity of women
Cyclical hemorrhage that appears every month and in which the functional layer of the endometrium is detached from the womb if there has been no implantation. It is made up of blood and endometrial cells.
It is a control, which consists of determining which are the fertile days of the woman, to know when she can get pregnant and when not, taking the menstrual cycle as the starting point of the process.
Name given to the set of cells that are created from the divisions of the zygote and that take on the appearance of a blackberry, hence its name and that will give rise to the blastocyst....
Technically the process is called cell compaction. Cells that divide unrelated make connections.
Term that refers to when a man does not have enough sperm to fertilize an egg. It is the main cause of male infertility.
Assisted reproduction technique, very similar to in vitro reproduction, although unlike in vitro, oocytes from an anonymous donor are used, instead of the patient's own.
Eggs are the female sex cells generated in the ovaries. They are fertile for 24 hours after their descent into the uterus and remain lodged in the fallopian tubes. When the ovum is fertilized by male sperm, it is called a zygote, being the beginning of pregnancy.
Acronym in English for Preimplantation Genetic Test. It is a technique used to detect possible serious hereditary diseases before carrying out the implantation of an embryo in the uterus. There are up to three variants of the test depending on the type of disease.
When a couple has no offspring after 1 year of regular intercourse (every two or three days) not protected.
It is the accumulation of various fluids inside the ovary. For example serum, pus, fat ... etc. They are not usually malignant and generally do not prevent pregnancy, although in some cases they negatively influence fertility. They are usually treated by laparoscopic surgery.
Capacity of the ovaries to produce eggs, after stimulation. It is closely related to the age of the woman.
Term to refer to the suboptimal fertility conditions of a man or a woman.
Acronym for Genetic Compatibility Test. It is a test that is done to future parents who want to have a child to find out if they have genes that can transmit diseases to the baby.
It is the temperature that the human body has, after sleeping a minimum of 5 hours. It helps us to know the fertile days of the woman to increase the chances of becoming pregnant.
Assisted reproductive techniques
They are also known by the abbreviations TRA. Set of treatments that help couples who have difficulties to conceive by natural methods to conceive....
These techniques include intrauterine insemination (IUI), in vitro fertilization (IVF), intracytoplasmic injection (ICSI), and donation of gametes (sperm or eggs). The treatment used in ART to induce the development of multiple follicles to obtain multiple oocytes in follicular aspiration is known as controlled ovarian stimulation (EOC).
Noninvasive Prenatal Test acronym in English. It allows detecting that the future baby may have a hereditary disease of which his parents are carriers but have not developed it, for this reason they are called recessive diseases. It is considered that only 10% of
Name of the cells that form the outer layer of the blastocyst and that later will be the placenta. It begins to be created in the early stages of pregnancy, providing nutritional elements to the embryo.
