[Preparation of human semen for in vitro fertilization procedures and intra-fallopian gamete transfer].

Techniques of "In Vitro" fertilization (IFV) and gamete intrafallopian transfer (GIFT) are proving to be successful in the treatment of infertility. We report here in detail the laboratory procedures of sperm processing for these two techniques also in the present work we pointing out the media quality control methods and the incubation time for the maintenance of spermatozoa fertilizing ability.

[Changes in follicular acid phosphatase levels in relation to oocyte maturity in humans].

The changes in enzymatic activity of acid phosphatase (AP) have an important role in ovulation, and it seems that there is relationship between ovocyte fertilization by spermatozoon. In this study AP enzymatic activity in follicular fluid of 32 patients of fertile age who underwent laparoscopy or laparotomy, was determined. Ovarian follicles were functioned in all the patients, and bloody follicles were discarded, as well as the ones without ovule.
