[Assesment of the woman's age as a main predictive factor of assisted reproductive technology treatment outcome].

Several factors could be used as a predictors of in vitro fertilization treatment outcome: female age, aetiology of sterility, previous ovarian surgery, embryo morphology and cleavage rates and also the technique of embryo transfer. The aim of the present study is to evaluate the role of the age to be used as a prognostic factor for the sterility treatment outcome. The tasks we assigned were to compare the several parameters: duration of the stimulation, number of retrieved oocytes, fertilization rate, implantation rate and clinical pregnancy rate after IVF/ICSI in different age's groups. The study results clearly demonstrate that in spite of decreasing number of retrieved oocytes after the age of 30, the fertilization rate remains elevated till 40 years. Regardless of this fact, the implantation rate and the clinical pregnancy rate were significantly lower after the age of 35. Reduction of the success rate in these cases showed that ART, despite of its renewals, is not the strategy for getting over the age in human reproduction.

[Vaginal echography in extrauterine pregnancy].

Twenty eight women with suspicion for extrauterine pregnancy were examined by a vaginal transducer. Extrauterine pregnancy was diagnosed in 18 of them, which was confirmed at the operation. There were no echographic data for tubal pregnancy in 10 of the women. Their further follow-up rejected the presence of extrauterine pregnancy. Three tubal pregnancies were discovered by routine monitoring of ovarian cycles. The immediate proximity of the vaginal transducer to the examined organs in the pelvis gives a possibility for exact topical diagnosis.

[Acromegaly and pregnancy].

Pregnancy in women with acromegaly is very rare. The introduction of dopaminergic treatment revealed new possibilities for conception. Four acromegalic women who conceived during a course of bromcryptin treatment and after an unsuccessful transsphenoidal adenectomy are presented. Two of the women have given birth to a normal child, the third woman aborted willfully and the delivery of the fourth woman is forthcoming. Bromcyptin was given during the whole course of pregnancy in progressively increasing doses up to 15 mg daily according to the increased levels of the somatotrophic hormone (STH). The action of bromcryptin on some hormones of the mother and the child is discussed. The mother's serum STH level increased in the course of the pregnancy progressively despite the treatment and fell after the delivery while the child's STH levels were normal.

[Echographic diagnosis of ovulation in healthy women].

Dynamic echographic changes in measures of the uterus, uterine mucosa, ovaries and dominant follicle during normal ovulatory menstrual cycle were established in 16 multiparas and 17 nulliparas. All measures undergo characteristic changes as they increase during follicular phase of the cycle and reach their maximum paraovulatorily. For establishment of ovulation the changes in anterior-posterior size of the uterus, uterine mucosa, diameter of the dominant follicle and qualitative changes, occurring in it, are of the greatest significance. Mathematical models are made, which allow a comparison and prognosis of the changes in the internal genital organs of a woman in respect to the ovulation.

Serum gastrin I concentrations of mother and newborn immediately after birth.

Serum gastrin I (GLU-GLY-PRO-TRYP-LEU(GLU)6-ALA-[formula, see text]-GLY-TRY-MET-ASP-PHE-CO-NH2) concentrations were investigated by radioimmunoassay in 50 mothers and their newborn infants immediately after birth. The mean serum gastrin concentration in maternal blood was 52.80 +/- 13.37 (SD) pg/ml, and in cord blood 84.12 +/- 42.90 (SD) pg/ml. Both values were significantly higher than serum gastrin levels found in normal, healthy, nonpregnant women (Mean +/- SD = 32.34 +/- 18.35 pg/ml). There were no statistically significant differences in the cord serum gastrin concentrations with respect to sex, weight and length of the infant and age and parity of the mother.
