[Significant bacteriospermia. Value and limits of sperm count in andrology].

The data concerning bacteriospermia--are very different in the literature. Asymptomatic andrologic patients, and as control group--patients of the outpatient department for male adnexitis--were studied. Cultivation of aerobic bacteria and mycoplasmas has been recently accomplished by quantitative bacteriological analysis and chlamydia diagnostic. The microbiological screening of 210 andrologic patients ejaculate has given the following results: 19.6% were sterile, 21.0% were colonised by apathogens, 59.1% were positive: 6.2% Mycoplasma hominis, 15.8% Ureaplasma urealyticum, 13.3% Chlamydia trachomatis, 51.9% other aerobic pathogens. 27.6% of samples contained more then one kind of bacteria strains. Quantitative isolation of aerobics and mycoplasmas in both andrological and male adnexitis patients groups showed the following distribution. In the andrologic groups 14.7% of samples contained 10(4) CFU/ml, 9.6% more than 10(4) CFU/ml aerobic bacteria; in the male adnexitis group nearly twice higher values could be observed (20.2% and 19.5%). The distribution of mycoplasma CFU/ml was the following; andrologie group: 20.1% of samples contained 10(4) mycoplasma CFU/ml, 37.5% more than 10(4) CFU/ml; in the male adnixitis group the identical values: 22.9%, 66.9%. Chi 2 statistical analysis showed significant difference ((p = 0.000) in the distribution of data in the two groups. On the other hand both of the groups contained all kinds of bacteriological concentration and even negative cases. Therefore authors suggest more biochemical investigations for detecting inflammatory diseases. Spermaparameters (motility and progressive motility) of andrological patients, divided by sperm concentration (cell number above and under 20 million/ml) and the degree of infection (non infected, slightly infected, and above 10(4) CFU/ml) were significantly different in the seriously infected group by variance analysis (p = 0.000).

Serum and seminal gonadotropins in normal and infertile men: correlations with sperm count, prolactinemia, and seminal prolactin.

Serum and seminal gonadotropins were evaluated in 30 normozoospermic and 30 oligozoospermic patients. Mean values of basal serum gonadotropins were higher in the oligozoospermic group than in the normozoospermic group: 3.8 versus 1.8 ng/ml and 3.3 versus 2.2 ng/ml for FSH and LH, respectively. Seminal FSH levels were comparable in the normozoospermic and oligozoospermic groups (0.8 versus 0.8 ng/ml, respectively) and were constantly lower than serum FSH levels in both groups. Seminal LH values were constantly higher than serum LH values in the normozoospermic group, whereas in the oligozoospermic group seminal LH values were higher, similar, or lower than serum LH values. However, no significant difference was noted between the two groups for seminal LH values: 3.6 (normozoospermic group) versus 4.1 ng/ml (oligozoospermic group).

[Sperm count and seminal biochemistry of high altitude inhabitants and patients with chronic altitude sickness].

Semen analysis has been studied in 9 healthy adult males from sea level (150 m), age 19-32 years old and 15 healthy males from high altitude (NA), 9 from Cerro de Pasco (4,300 m) and 6 from Morococha (4,540 m), ages 19-45 years old. Five patients with chronic mountain sickness (MMC), whose ages ranged from 23 to 52 years old were also studied. The volume and motility were similar in NA and MMC, however both were below than in sea level subjects, but still in the normal range; the number of spermatozoa per 1 ml was lower at sea level than in NA and MMC, although the total number was higher at sea level due to the higher semen volume. Fructose at sea level was 356 +/- 53 mg/100 ml (mean +/- S.E.) which is similar to NA 237 +/- 45 whereas a MMC was significantly lower, 142 +/- 60. Citric acid was lower at sea level than in NA and MMC. Na, K and Cl, were similar among the three groups. The lower concentration of fructose in MMC parallels the decreased testicular function already found in these groups. However it is worthy to point out that the fertility is preserved in all the groups. The normal reproductive function in MMC is against the concept that this process occurs as a consequence of environmental disadaptation.

Quantitative post-coital test: sperm counts in cervical mucus after enzymatic liquefaction.

The post-coital test involves direct microscopic examination of sperm number and motility in cervical mucus. The results depend on the quality of the mucus and the distribution of spermatozoa within the sample. To progress from such qualitative data to quantitative measurements of the spermatozoa present in post-coital mucus, we have developed methods to measure sperm concentrations in enzymatically liquefied post-coital cervical mucus. The mucus score and sperm motility were measured prior to mucus liquefaction, and, together with sperm concentration, they allowed the calculation of the total number of motile spermatozoa present. A combination of bromelin and glycosidases proved to be more efficient in achieving reliable mucus liquefaction than treatment with bromelin alone, and was used to liquefy a series of 36 post-coital test samples. Total sperm numbers ranged between 19 x 10(3) and 16.8 x 10(6). Of the samples, 75% contained < 3 x 10(6) spermatozoa, and 39% contained < 1 x 10(6) spermatozoa. Sperm motility was very high in these samples, except for a distinct subset of samples (19%) in which the total sperm motility was markedly decreased ( < 20%). The measurement of sperm concentration in liquefied cervical mucus will help to determine normal values for the post-coital test, and to estimate the number of motile spermatozoa reaching the upper female genital tract.

Personality, coping and sperm count.

Previous research has suggested an association between personality traits and coping, as well as between coping and sperm concentration. In the present study, both domains of research were combined, leading to the formulation of specific hypotheses. A total of 54 healthy volunteers were given questionnaires twice to assess personality traits and coping behaviour. Participants also produced up to three semen specimens. As hypothesized, active coping was correlated negatively with neuroticism (r = -0.59) and positively with conscientiousness (r = 0.56), whereas sperm concentration was correlated negatively with both active coping (r = -0.28) and conscientiousness (r = -0.37). The relationship between conscientiousness and sperm concentration did not appear to be mediated by active coping. Although the correlations were small, evidence is mounting that psychological aspects and male sperm parameters are not independent. The present findings, however, should not lead to the conclusion that conscientiousness and active forms of coping are characteristics of infertile patients.
