Married injection success rates for IVF Influenced Season

Successful or unsuccessful attempts at artificial insemination fertilization or mating syringe to test tube baby was also influenced by season. If done in spring, the chances of conception greater than in seasons other.

Scientists have long known that birth rates naturally tend to increase at certain seasons. However, never known for sure what the cause, only to the extent alleged that the temperature or the temperature affects the chances of conception.

Recently scientists revealed that a similar trend is also happening on the technology of artificial insemination and IVF. Chances of success in these methods also vary in each season in one year.

The team of researchers from Sao Paulo, Brazil, led by Dr. Daniela Braga revealed that after watching 1932 patients who underwent mating syringe. Each masign participants underwent the procedure on the season
vary in the same year.

When fertilization occurs, the opportunity to obtain embryos with the quality of the same good are not much different in every season. But for the occurrence of fertilization, it appears the differences in success rates is significant in several seasons.

Conception carrying the most common, if done in the spring, namely 73.5 percent. Row below it is the fall of 69 percent, summer 68.7 percent and winter 67.9 per cent.

The researchers also noted increased production of the hormone 17-beta estradiol in the spring. Hormones are one form of estrogen, which is produced by women during their stay in the fertile age ie after puberty and before menopause.

"The level of success in the spring higher almost 1.5-fold. This means if you have difficulties to fertilize, attempted to do in that season," said Dr. Braga is quoted from ScienceDaily.
Alleged causes of these differences are changes in one neuron in the brain that produce gonadotrophin-releasing hormones (GnRH). These hormones regulate the release of estradiol, which is observed highest in the spring.

Up to a certain level, increased production of estradiol is needed in the process of maturation of the egg. Levels of estradiol are sufficient to make the egg easier to be fertilized.
