Ova bank

A bank of ovules is a dependence of assisted reproduction clinics that aims at freezing and storage of ova in order to use in assisted reproduction techniques such as in vitro fertilization. The ovules are stored in special containers. The receipt of donated ova is, for some women, the only option for mothers, and it is possible because there are donors who voluntarily decide to lease its ovules. Besides donor ova storage, preservation of frozen ova is useful when the patient is to undergo cancer treatment (producing damage in the ovaries ) when you want to postpone motherhood or when you need to accumulate ovules because it has a low response ovarica. Unlike sperm, which can be frozen without loss of quality, the eggs produce ice crystals can destroy the cell inside. This situation has gotten reversed with the technique of vitrification. ...

4D ultrasound

The 4D ultrasound consists in obtaining four-dimensional images per second. This will get to see the baby and moving in real time. Best 4D ultrasounds are obtained between 24 and 30 weeks gestation. Thanks to the proportion of amniotic fluid and intermediate size baby enable optimal viewing. ...

Assisted reproductive technologies

Assisted reproduction techniques are useful to help a woman become pregnant. Some of these techniques include artificial insemination or in vitro fertilization (IVF). ...

Egg donation

Egg donation, egg donation also called, is the process of delivering anonymous, altruistic and selfless egg in order to help women who wish to have a child and can not process for different reasons. The requirements are to contribute between 18 and 34, have health conditions healthy without having any sexually or inheritance and have legal authority to grant permission. Before performing this procedure, the patient must pass a medical examination to assess the state of physical health with a medical review that takes into account family history and a gynecological examination, and psychological. ...

Embryology

Embryology is a science that studies the prenatal development of organisms.

Fertility Study

The fertility testing is a medical protocol that aims to diagnose the causes of infertility in order to find the necessary help to get pregnant, within which can be seen assisted reproduction techniques. The study is conducted to the two partners, if they take at least a year trying to conceive a child without contraception without success. Studies generally last between one and two months, they are relatively simple and consist in finding out if the man has a sperm of normal characteristics, if the sperm reach the uterus after intercourse, if the woman has a right ovulation or the uterus and the fallopian tubes are normal. To do this, the fertility study may include tests such as transvaginal ultrasound, bacteriologías, hormonal study and hysterosalpingography, in the case of women; in the case of men, sperm count and sperm capacitation test. ...

Frozen Embryo Transfer

Embryo transfer is the introduction of one or more embryos into the woman's uterus through the cervix. It is the culmination of a technique of in vitro fertilization. Embryo transfer can be carried out with embryos of the in vitro fertilization or embryo from a previous cycle (which have been frozen for preservation). In the case of frozen embryos, to perform the procedure, the first woman's uterus is prepared, the embryos are brought to a physiological temperature (37 °) and transferred into the uterus. The transfer is performed under ultrasound guidance to know what is the ideal place to deposit the embryos. In recent times, it has implemented a method of embryo selection called embryoscopy, which controls the embryo from the moment of fertilization until the transfer to the uterus. ...

Infertility

  Infertility is the inability to father children after a period of 12 months or more keeping unprotected sex. This term should be distinguished from sterility, which is the absolute inability to achieve pregnancy. According to the World Health Organization, infertility affects 15% of couples. In approximately 40% of cases, it is male infertility; in another 40%, the problem comes from the woman, and the remaining 20% ​​either of the two, or unspecified causes. The causes may be varied: genetics, immune, endocrine, toxic, infectious, etc. So both partners must undergo medical tests. Treatment may include techniques such as in vitro fertilization, artificial insemination, transfer of zygotes to the fallopian tubes, intracytoplasmic sperm injection. ...

Oocytes freezing

Freezing oocytes (immature ova ) is a technique used in assisted reproduction that serves to preserve, ie, to maintain their structures in latent form for a while. The oocytes that survive the thawing have a similar to those that have never frozen behavior. This means that their quality is not altered, and subsequently can be fertilized with sperm from the partner or from a donor in a laboratory and then implanted in the uterus of women those embryos that are developed, leading to a possible pregnancy. Oocytes therefore are not fertilized before freezing. Before starting treatment, the patient must take medication to produce a large number of ovules along two or three weeks. ...

Partner ova reception treatment

Receiving eggs from the couple (CLOTHING) is an assisted reproduction treatment aimed at gay couples formed by women. It is a technique of in vitro fertilization in which one of the women of the couple undergoes ovarian stimulation to produce mature eggs, which are extracted through an ovarian puncture. Subsequently, an egg is removed and fertilized with sperm from a donor. The resulting embryos are transferred into the uterus of another partner, which is being conducted Dead pregnancy, using the same procedures used in conventional treatment. Receiving eggs of the couple is a new technique from the social point of view, but medically not mean any changes in laboratory routines. ...

Preimplantation Genetic Diagnosis

Preimplantation genetic diagnosis is a technique used in IVF treatments for selecting embryos to avoid genetic and chromosomal diseases. Under Spanish law, this technique is authorized for the detection of serious hereditary diseases, early onset and for which there is still no cure. In these cases, preimplantation diagnosis can select from eggs fertilized embryo gene that free of the disease before being transferred to the uterus. The diagnosis is made based on the analysis of single cell embryo to determine whether or not carrying a particular gene mutation, and select or dismiss it for implantation. Thus, it improves the chances of success of IVF treatments and the risk of abortion is reduced.   ...

Repeat Abortion

Sperm Bank

A sperm bank is a department with assisted reproduction clinics this intended for freezing and storing sperm for later use in fertilization of ovules in assisted reproductive techniques such as in vitro fertilization. It uses a sperm bank when the woman has no partner, when couples have infertility problems by male end factor, or when there is a high risk of transmission of paternal hereditary disease, among other cases. Frozen sperm is also useful in the case of men who are about to undergo chemotherapy or radiotherapy, because these treatments could jeopardize their future fertility. Besides, donor semen anonymously must meet the requirements indicated in the applicable law and subject to some controls to donate the sperm bank. The quality of the frozen samples does not deteriorate over time, but patients are required by law to report periodically to the bank's desire to continue keeping them. ...

Sperm DNA fragmentation

Sperm DNA fragmentation, fragmentation or sperm refers to injuries, damages or breakages in the sperm genetic material, and is a major cause of infertility in man. The causes of this fragmentation of DNA may be intrinsic (by improper maturation of sperm abnormalities or genetic type) or external (for damage induced by radiation or chemotherapy treatments for episodes of high fever, acute or chronic inflammatory disease , among others). The technical study of DNA fragmentation of sperm improves the chances of success in IVF treatments. Besides, in some cases, the oocyte can repair spermatic fragmentation, depending on the type and severity of the injury and oocyte quality. ...

Spermiogenesis

Spermatogenesis is the name given to the last phase of the formation of sperm. During this stage of maturation, cells are spermatids causing an increase in queue size and decreasing the sperm head. This series of complex transformations leading to the final end of sperm constitution which male cells are specialized in transferring the oocyte DNA. The mature sperm is released through the seminiferous tubules, which are small tubes that are within the testes, responsible for producing sperm and the hormone testosterone. The approximate duration of this process is two and a half months. ...

testicular biopsy

Surgical technique consisted in obtaining a sample of testicular tissue through an incision in the scrotum. The objective of this procedure is to diagnose some kind of illness or so therapeutic for assisted reproduction. In the first case a sample of testicular pulp is taken to assess testicular function and testicular tissue discover whether or not sperm produced. Also you can perform to a genetic or meiosis study. Regarding the therapeutic target, biopsy is performed to remove immature sperm, if one exists, for the purpose of assisted reproduction and freezing a sample buffer for reproduction cycles. Before biopsy is a preliminary study of the state of the male, both physical examination as a hormonal analytical ago to establish if required performing this test. ...
