Different anaesthetic procedures that were used during an in vitro fertilisation and embryo transfer (IVF-ET) program have been analysed in order to determine their influence on plasma levels of estradiol, progesterone, prolactin, and
beta-endorphin
and results of
IVF
-ET. METHODS. Fifty-four patients awaiting transvaginal oocyte aspiration were randomised into three groups: (1) anaesthesia with ketamine as an induction agent and analgesic (n = 20); (2) general intubation anaesthesia using thiopentone for induction and enflurane for maintenance (n = 18); and (3) no anaesthesia (n = 16). Estradiol, progesterone, prolactin, and
beta-endorphin
were measured from day 3 to 14 referring to follicle aspiration. Differences between preoperative hormone levels and their intra- and postoperative peaks were analysed using the Kruskal-Wallis test (P < 0.03). The results were corrected using the Holms method (alpha = 0.05). RESULTS. No differences were observed in estradiol and progesterone levels (Figs. 1, 2). Prolactin levels were 1.4 times higher (P < 0.001) when ketamine was used and 2.2 times higher (P < 0.001) after short general anaesthesia than in the control group (Fig.3). Similar results were observed with respect to
beta-endorphin
: in comparison with the control group we found significant elevation by a factor of 2.1 when ketamine was used (P < 0.001). The discrepancy became even more marked with general anaesthesia:
beta-endorphin
was 3.9 times higher compared to the controls (P < 0.001) (Fig.4). Comparing the two groups who were given anaesthetics, prolactin and
beta-endorphin
levels were also significantly different (P < 0.001). The
IVF
procedure itself did not appear to be affected by different anaesthetic procedures during oocyte aspiration (Table 2). CONCLUSIONS. The increased prolactin and
beta-endorphin
plasma levels associated with ketamine and general anaesthesia reflect a significant alteration of the observed hormone levels. When anaesthesia is indicated, we try to avoid general intubation anaesthesia in favor of ketamine.

Screening for HIV in China began in 1984, with the first AIDS case appearing in 1985. 305,280 sera were tested as of 1992, of which 379 were seropositive for antibodies to HIV. Of these 379 individuals, there were 4 hemophiliacs identified in 1985, 1 homosexual male, 4 individuals returning from Africa, 365 drug addicts and 2 spouses. 68 foreigners and 1 Chinese hemophiliac from Hong Kong also tested seropositive. Concern is expressed over the psychosomatic trials of infected women who feel unable to discuss their HIV status with family members for fear of influencing their role as primary caregivers and sex partners. Without access to medical therapy and support groups, these women no doubt feel isolated. Non-directive counseling is recommended for seropositive women during pregnancy. AIDS patients have reduced natural killer cell cytotoxicity. Seminal plasma also suppresses several immune responses. The pathogenicity of HIV, however, has yet to be determined. Fatty acid metabolism and
Beta-endorphin
are discussed in the context of therapeutic approaches. HIV/STD interactions are finally considered with individual attention given to bacterial vaginosis, hepatitis B, Chlamydia trachomatis, Herpes Simplex virus, microbiological contaminants of the vagina bacterial vaginosis, syphilis, mycoplasmas/epididymitis, bacterial prostatitis, and
IVF
culture media infections.
