At the beginning of the third week of pregnancy there is ovulation and fertilization. The woman has not had her period so she will not know that she is pregnant.
On the first day, at 16-20h post-fertilization, the zygote appears. On day two, the embryo has four cells, day three eight and day fourteen, at this moment it is called a morula. The fifth day follows the increase in cells and is called a blastocyst.
On the sixth-seventh day the embryo reaches the uterus and begins its adhesion to the endometrium, implantation. Normally the woman during this week does not have any symptoms.
Tubal ligation consists of preventing the passage of sperm into the tubes, thus preventing fertilization.
The reversal of tubal ligation is not always satisfactory, the factors that may influence are age, time since surgery, and the technique used. In women under 34 years can reach 70% of pregnancies.
Another important factor is the length of the tube after surgery, which must be more than 4 cm.
We can consider reversing a tubal ligation in women under 34 years old and with a residual tube longer than 4 cm.
It is a "gonadotropin-releasing hormone antagonist" drug and acts against the action of this hormone (GnRH) produced by our hypothalamus.
Orgalutran is used to prevent the premature release of LH, which can cause spontaneous ovulation. It is used in IVF cycles to prevent ovulation because without its effect the risk of ovulation is high and would produce a significant reduction in the number of eggs retrieved in a follicular puncture.
The sperm ducts are made up of the epididymis, the vas deferens, the ejaculatory ducts and the man's urethra. They constitute a set of ducts whose function is to liberate the spermatozoa to the outside by means of ejaculation.
Anything can happen during 2WW. Since not noticing any symptoms to begin to feel the typical symptoms of pregnancy: tiredness, nausea, abdominal discomfort like menstruation ... Sometimes you can even bleed a little.
Klinefelter syndrome or 47,XXY is a genetic abnormality that occurs as a consequence of an incorrect division of homologous chromosomes during meiosis, which give raise to the gametes of one of the parents. It can also occur during the first divisions of the zygote.
Males affected by it suffer from hypogonadotropic hypogonadism, gynecomastia, learning disabilities, and infertility. It is the most common genetic disease in males. Some men, however, do not have symptoms, and they don't know that they have this condition until they are adults and have infertility issues.
Hypospadias is a birth defect that affects male babies. With this conditions, the urinary meatus is located in a place other than the external urethral orifice, such as the scrotum. There exist various types of hypospadias, from mild to most severe.
The fact that a woman has had repeated miscarriages in the past has nothing to do with the day of the embryo transfer. In most of the cases, it is associated with the chromosomes of the embryos. Keeping this in mind, ideally the best treatment option in these cases would be IVF with PGD (Preimplantation Genetic Diagnosis). With PGD, we examine 6-8 cells of each embryo. It allows us to find out which embryos are genetically norma and which don't.
By blastocyst culture we refer to keeping the embryos in the incubator until day 5-6 of development, that is, until they reach blastocyst stage. By doing this, we perform a much more thorough embryo selection process. The fact they they are capable of making it to blastocyst means that they have a greater implantation potential, as it was able to stay longer in the lab. Pregnancy success rates depend on age, though.
