[Hematometra & Listeria monocytogenes]. / Hematometra por Listeria monocytogenes.

The hematometra is a nosological entity that may not always be attributed to an embryonic defect of the paramesonefros; cervical-vaginal infections such as etiological possibilities due to Listeria monocytogenes (Lm), cervix malignant neoplasias, iatrogenias due to endometrial ablation with Lasser, traumatic bloody uterine curetage and because of cervical cryocoagulation or electrocoagulation are also mentioned. The case to be reported is from a woman in reproductive stage, who is 32 years old, and had menarca at the age of 13, starting her sexual life at 31, not using any method to control her fertility. When having an eight-week amenorrhea after 8 months of marriage, she visited the doctor for assumed pregnancy, within the prenatal analysis a pelvic echographic study was requested, finding out images that we concluded as hematometra, having been drained and demonstrated the presence of LM by anti-Lm antibodies, being administered Azitromicina and Espiramicina.

Endometriosis is an ailment which has no exact etiology due to its uncertain genesis, its inception can develop unnoticed, its silent evolution makes it difficult to identify it until a cardinal symptom appears and its semeiology provides us facts to integrate a diagnosis, it is an entity that does not have relation while and/or with the reproductive stage, neither with the parity, but we are aware it occurs in its different stages, varying from 9% to 33% in the reproductive cycle, it can be recurring after being medically or surgically treated, appearing endometriomas in it or in the infundibulum stump in the latter case. It is characterized by a collagenosis, endometrio abnormal implant out of the uterus cavity, thereby generating and inflammatory process in the zone of implant, increasing the cytokines production (polypeptide secreted by the lymphocytes and macrophages playing an important role in the immunological response), involving a dysfunction in the hypothalamus-pituitary-ovarian, altering the endocrinos physiology; regarding the genetic aspect, alterations in the chromosomes 4.9 in the Endometriosis frames have been found. The human semen preparation with half Ham F 10 enriched with ascorbic acid is described. In cases of permeable tubes or FIVTE.

[Assisted reproduction. Alternatives]. / Reproducción asistida. Alternativas.

From the first publications about fertilization in vitro (FIVTE) Patrick Steptoe and Robert Edwards, added several knowledges and new concepts in modern Gynecology, so starting a new era of Reproductive Medicine, so ideating a series of programs and methodologies to emulate the physiological ovarian cycle; with this concept Ricardo Asch carries the transference of gametes to tubes and calling this procedure GIFT. These methodologies with a high technology have been called Assisted Reproduction, which is reviewed in this paper.

[Preparation of human semen for in vitro fertilization procedures and intra-fallopian gamete transfer]. / Preparación del semen humano para los procedimientos de fertilización "in vitro" (FIVTE) y transferencia intratubaria de gametos (TIG).

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]. / Modificaciones en los niveles de fosfatasa ácida folicular en relación con la madurez ovular en el humano.

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. The ovule was morphologically classified according to complex ovocyte-cummulus-crown radiated in three groups: immature, mature or pre-ovulatory and atresic or post-ovulatory. AP levels in follicular fluid, containing immature ovocytes (0.5 +/- 0.3 UBL) were significantly lower, p greater than 0.05, than AP levels for follicles with mature ovocytes (3.7 +/- 1.3) and postmature (4.8 +/- 3.2); there were no significant differences for AP values in these last two groups. These findings show that these AP levels could be used as an indicator of follicular immaturity, and to choose the optimal time for follicular punction for the in vitro fertilization and gamet transference procedures.
