Sperm motility improvement: comparison of two methodologies of reproductive techniques.

The objective of this study was to compare two methods for the extraction of high motility sperm; washed semen and swim-up techniques, on 172 ejaculates from 53 patients with suspected infertility. High quality motile sperm had been essential for the success of the assisted reproductive procedures, in which these patients were enrolled. Semen analyses were performed according to the criteria recommended by the WHO.

[The use of clomiphene and menotropins as inducers of multiple follicular growth in a program of in vitro fertilization].

In our IVF & related techniques program, clomiphene 50 mg was used from days 2 to 6 of the cycle in 20 patients and 20 cycles. (17 IVF patients and 3 GIFT patients) menotropins were also used in 2 different schemes: a) 2 ampules in alternated days (12 cases) and b) one ampule daily (8 cases). The patients with the daily scheme required lesser total dose of menotropins and developed higher estradiol levels, although this had none statistic significance, and they also developed a greater number of follicles.

[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.

[Clomiphene as an inducer of multiple follicular growth].

In our IVF + ET & GIFT programs we gave 100 mg of clomiphene from cycle days 2 to 6 in 35 cycles of 32 infertile patients. Serum estradiol curves were made establishing 3 types of curves: 1. climbing curve which was subdivided in curve A (6 cycles) with more than 600 pg/mL of estradiol, more than 4 follicles of a mean size of 35 mm; curve B (13 cycles) with an estradiol range from 300 to 600 pg/mL, 2.

[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.
