Traditionally in the archives of these procedures lies method that, in which inseminaba a woman depositing you the ejaculate in the vaginal cul-de-sac and around the neck, which had high failure rates, is now obsolete. Known it is, that the ejaculate has two fractions that are qualitatively different, the first fraction is small, but rich in sperm and these in turn, are of great quality, motility, morphology and quantity, while the second fraction of the ejaculate is less worth in comparison with the first. In this work we have used the first fraction of the ejaculate to carry out artificial insemination during previously studied and selected to apply for couples of a treatment of this nature, which have compared it with the sample studied classical insemination is of 24 couples and we have it divided into two groups, each of them consisting of 12 couples, couples in Group A, were inseminated with the first instalment of the ejaculate, while group B pairs were inseminated with the ejaculatethe 24 selected couples are patients of the service of Gynecology of the Central Hospital of North of Essalud Almanzor Aguinaga Asenjo and all received the same protocol of ovulation induction in screening ultrasound of the same and of insemination. The results were tabulated and distributed in boxes two-dimensional, subsequently analyzed, with the following results. 1.-The age groups most affected, were 29 to 32 years for women and 33 to 36 years for men.
2.-The 86.9% of infertile couples studied had already five years with marital infertility diagnosis. 3. 75% Of the causes of sterility treated with the Homologous Artificial insemination have been sperm disorders type Oligospermia and Oligo astenospermia. 4. The 54.16% of treated couples presented the diagnosis of primary infertility. 5.-In the first fraction of the ejaculate, the amount obtained in cubic centimeters ranged from 0.6 to 1.2 cubic centimeters. 6. The 91.36% of treated patients, were inseminated in the first five cycles.
7. A total of 306 inseminations in this experimental work, reason for the present study took place. 8. There were a total of 530 ovarian ultrasounds, trans – pelvic, the 612 that were planned to be carried out given the magnitude of the work. 9.-The number of inseminations per cycle was three, counted from the beginning. 10 – In the 58.33% of cases, the follicles reached measured on average 32 mm. 11 – The 66.6% of the cases that reached success, i.e. pregnancy, were in relation to pictures of Oligospermia. 12 – Cycles in cases that reached the success averaged 3.1. 13 – The patients inseminated with the first fraction of the ejaculate achieved success in the 20.84%, whereas patients inseminated with the ejaculate achieved a success rate of 4.1%. 14 – 25% Was reached success through homologous Artificial insemination. 15 – technical failures trans-inseminacion were the reflux of semen into the 1.6% and uterine contractility in 1.3% 16-not found complications post insemination. OVERVIEW the insemination of sterile women, with the first fraction of the ejaculate, represents a workable, reasonable, ambulatory and economic option and which must still be taken into account in health institutions in low complexity.
