PURPOSE: literature reports show that there are no conclusive data about the association between endometriosis and the concentrations of hormones involved in the control of reproduction. Thus, the present study was undertaken to determine FSH, LH, estradiol (E), progesterone (P), and histamine (Hi) concentrations in serum, peritoneal fluid and follicular fluid of women with and without endometriosis. METHODS: the extent of the disease was staged according to the revised American Fertility Society classification (1997). For the collection of serum and peritoneal fluid, 28 women with endometriosis undergoing diagnostic laparoscopy were selected (18 infertile women with endometriosis I-II and ten infertile women with endometriosis III-IV). For the control group, 21 fertile women undergoing laparoscopy for tubal sterilization were selected. Follicular fluid was obtained from 39 infertile women undergoing in vitro fertilization (21 women with endometriosis and 18 women without endometriosis). RESULTS: FSH and LH levels in serum, peritoneal fluid and follicular fluid did not differ significantly between groups. On the other hand, E and P concentrations in the peritoneal fluid were significantly lower in infertile women with endometriosis (E: 154.2±15.3 for stages I-II and 89.3 ng/mL±9.8 ng/mL for stages III-IV; P: 11.2±1.5 for stages I-II and 7.6 ng/mL±0.8 for stages III-IV) in comparison with control women (E: 289.1 ng/mL±30.1; P: 32.8±4.1 ng/mL) (Kruskal-Wallis/Dunn tests; p<0.05). In serum, estradiol and progesterone concentrations followed the same pattern. In the follicular fluid, E and Hi concentrations were significantly lower in women with endometriosis (E: 97.4±11.1 pg/mL; Hi: 6.6±0.9 ng/mL) in comparison to women without endometriosis (E: 237.5±28.5 pg/mL; Hi: 13.8±1.3 ng/mL) (Student t-test; p<0.05), while progesterone levels revealed no significant difference between groups. CONCLUSIONS: our results indicate ovary dysfunction in women with endometriosis, with reduction on E, P and Hi concentrations, which may contribute to the subfertility often associated with the disease.

PURPOSE: to evaluate experimentally the effects of antiretroviral drugs used alone and in association upon the fertility of pregnant Wistar rats and the perinatal effects on the offspring. METHODS: adult female pregnant Wistar rats weighing 200-230 g were used. The antiretroviral drugs zidovudine (AZT), lamivudine (3TC) and nelfinavir (NFV) were used alone and in association at daily doses of ten times the dose normally used in pregnant women, proportionally to the animal's body weight. Seven groups were studied, including the control one. The experiment started on day 0 and the pregnant animals were sacrificed on day 21. The alive and dead fetuses, the total implantation sites and the total numbers of corporea lutea were used to calculate the fertility values. The statistical analysis was performed by Student's t test and by the Mann-Whitney test. RESULTS: there were no significant statistical differences regarding preimplantation loss and implantation efficiency values of the rats treated with isolated and associated antiretroviral drugs. There was a significant increase in the postimplantation loss values (control group: 7.6%; drug groups variation: 20.2-26.7%), a decrease in the fetal viability values (control group: 92.4%, drug groups variation: 73.3-79.8%), and a decreasing number of fetuses per animal (control group: 14.7; drug groups variation: 11.1-12.7). There was a significant weight reduction of the female rats and of the offspring of animals treated with 3TC, AZT + 3TC and AZT + 3TC + NFV. CONCLUSION: with the administration of high antiretroviral doses, important fertility effects could be observed, which showed that less histotoxic antiretroviral drugs must be studied in order to warrant the safety of using these medicines in pregnant HIV-1 - infected women.
