Artificial insemination is a method of insemination in which sperm is deposited in the vagina of women through mechanical means that replace copulation, and in the near ovulation time. In this way, the sperm travel up the fallopian tubes is shortened, and therefore, there are more likely to approach the more sperm egg. The aim is to increase the chances of pregnancy in couples who have difficulty conceiving a child. The technique consists, first, to collect a semen sample which is treated in the laboratory to concentrate sperm. The doctor inserts a speculum into the vagina to see the cervix and injecting the sperm into the uterus. Usually, it's a bit painful process, and usually accompanied by ovarian stimulation techniques.
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 vit 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. ...
Intracytoplasmic sperm injection (ICSI) is a novel technique assisted reproduction whereby a sperm into an oocyte injected with a microneedle. The difIntracytoplasmic sperm injection (ICSI) is a novel technique assisted reproduction whereby a sperm into an oocyte injected with a microneedle. The difference with conventional in vitro fertilization is not in traditional sperm incubated the egg for fertilization to occur, but is forced by injecting the sperm fertilization. But the probability of success is the same in both procedures have in common that the patient should be submitted in both techniques to a previous ovarian stimulation. Intracytoplasmic sperm injection is indicated when a man has a concentration of very small or low sperm mobility, when it has undergone a vasectomy, when presenting an infectious or infertility causes immune disease, among others.

In vitro fertilization (IVF) is the union of egg and sperm artificially in the laboratory in order to obtain a suitable number of embryos to transfer to the uterus and fertilize; thus she becomes pregnant women. This procedure can solve certain cases of infertility, and is usually resorted to when other assisted reproduction techniques have failed, such as artificial insemination. Insemination of the oocytes can be performed by conventional technique or IVF using intracytoplasmic sperm injection (ICSI), which is used mainly when there is a male sterility factor.
What is infertility?
According to the World Health Organization, infertility is a pathology of the reproductive system that makes pregnancy impossible. Infertility affects the couple, both men and women, who can not have a child naturally. There are two types of infertility. Primary infertility, which affects couples who have not achieved a pregnancy after at least one year of sexual intercourse without contraception, and secondary infertility, in couples who have been able to get pregnant and can not now.
Symptoms and causes of infertility can vary between men and women
Symptoms of infertility
The symptoms of infertility can vary in men and women.
In women, the symptoms may be related to the menstrual cycle and ovulation. They can be abnormal menstruation, with bleeding more abundant or less than usual; irregular menses, when the number of days between each menstruation is different every month; amenorrhea, that is, absence of menstruation, and dysmenorrhea, very painful menstruations. Symptoms may also occur without regard to menstruation, these being the appearance of whitish flow in the nipples (without having any relation to breastfeeding) or pain during sexual intercourse.
In men, the symptoms of infertility related to sperm can be the presence of semen of yellow or green tonality, red or brown spots; ejaculations very odorous, thick, watery or with little amount. Also, they can witness symptoms unrelated to semen such as: changes in hair growth, alterations in sexual desire, erection problems and stiffness in the testicles.
What are the causes of infertility?
The causes of infertility common between men and women are:
Congenital defects of the reproductive system
Cancer, tumors, chemotherapeutic drugs, radiotherapy.
Excess of alcohol consumption
Scars due to sexually transmitted infections, abdominal surgery or endometriosis.
In women, infertility can arise as a result of:
Neoplasms in the cervix and / or uterus, ovarian cysts, polycystic ovarian syndrome.
Tubal ligation or reanastomosis.
In men, the causes of infertility can be:
Consumption of certain medicines, such as cimetidine, spironolactone and nitrofurantoin
Scarring due to sexually transmitted diseases, injury or surgery
Toxins in the environment
Vasectomy or failure of the vasovasostomy.
Can infertility be prevented?
As a general rule, if the infertility is genetic or caused by an illness, it can not be remedied. However, there are certain things that favor infertility that can be avoided:
Take preventive measures against Sexually Transmitted Diseases (STDs).
Do not consume drugs. Do not drink alcohol frequently or in excess.
Maintain good personal hygiene.
In women, go for a gynecological examination once a year once they are sexually active.
In men, wear loose underwear and avoid hot baths, saunas and radiations.
What is the treatment of infertility?
The methods to treat infertility in men and women are the taking of hormones to balance the hormonal imbalance, the use of supplements to improve fertility and the taking of antibiotics when suffering from infection. In women, undergoing minor surgery that removes blocking tissues or scarring of the fallopian tubes, uterus or pelvic area is another option. If this does not work, you can proceed to assisted reproduction techniques.
Ovarian stimulation is used to increase the number of eggs in women who want to undergo assisted reproduction technique, either by artificial insemination or in vitro fertilization, because they have difficulty getting pregnant. The treatment involves placing a subcutaneous injection of a hormone prepared daily from the third day of the menstrual cycle. On the fourth day begins tracking the number and size of follicles (where the eggs will develop future) by vaginal ultrasound to determine the best day for the egg retrieval. Oocytes are extracted for several cycles to fertilize and then implanting the embryo in the uterus. Ovarian stimulation may increase the risk of a multiple pregnancy. Meanwhile, intercourse is usually applied directed, a treatment that involves sex on your most fertile days.
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.
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.
The adoption of embryos refers to the realization of a treatment to achieve pregnancy with embryos that have lost their destiny by their biological parents. When a woman is subjected to a treatment of assisted reproduction, there is usually implement all embryos. The law establishes what is the fate of surplus embryos, which must be properly frozen and stored. The options are: implantarselos the same woman (if a posteriori wants to try to get pregnant ), destroy them, donate them for research or donated to other patients. If a woman decides to donate their embryos to other couples problems playing MAY BE GRANTED. In such cases, physicians and anonymous donors often look similar physically to future recipients parents.
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.
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.
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.
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. ...
Prenatal diagnosis is the set of tests to find the right training and development of the fetus. Different techniques are both invasive and noninvasive.
- Test of fetal DNA in maternal blood. From week 10 you can know the risk of Down syndrome or other abnormalities related comorsomas.
- Ultrasound. Several throughout pregnancy are performed. Three months to detect some images of markers comosomopatías and second you can diagnose possible malformations.
- Amniocentesis. Get amniotic fluid surrounding the fetus to detect chromosomal abnormalities.
The abortion of repetition is the loss of three or more consecutive pregnancies before 20 weeks of gestation. Each case must be individualized, age of the woman, the circumstances surrounding the lost or anxiety partners should be aspects to consider.
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, 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. ...
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. ...
