ABSTRACT In order to elucidate the mechanism of disturbances of gonadal hormones secretion in anorexia nervosa 14 female patients were investigated. A control group also consisted of 14 women of the same age. The serum LH, progesterone, oestrogens: oestrone + oestradiol (Oe1 + Oe2), oestriol (Oe3) and testosterone were determined by radioimmunological methods. In patients with anorexia nervosa the serum testosterone and Oe3 concentrations were dramatically elevated, whereas LH, progesterone and Oe1 + Oe2 were decreased as compared with the control group. Considerable weight gain induced by cyproheptadine treatment caused a normalization of the serum testosterone and Oe3 concentrations in all the patients. A negative correlation between the testosterone level and the deficit in body weight was observed. The mechanism causing the dramatically high serum testosterone concentration in the female patients with anorexia nervosa is discussed.

The current study was presented to conclude the influence of different ratio of pomegranate peel powder (PP) in feed of Karadi male lambs, they divided to 4 groups (0% as a control, 1% treatment 1, 2% treatment 2 and 4% as treatment 3), on scrotal circumference (SC), scrotum height (SH), body weight (BW) and blood serum testosterone concentration (T). In this study, sixteen (16) of Karadi male lambs used with 24.30 ± 0.40 kg weight and with 4-5 months old, all lambs have been randomly divided equally into four (4) groups and individually penned in a box for during 63 days. Results in our study showed that SC was significantly different and recorded higher 17.875±0.54 cm in group that fed on 1% PP, also SH recorded higher and significant different in group fed on 1% PP compared with other groups 10.000±0.32 cm. Average blood serum testosterone reduces in all groups compared to control group that fed on 0% of PP (11.418±0.15 n.mol/L). Final body weight in our study had significantly different (P < 0.05) between groups, 1% PP recorded higher weight (34.9 ± 0.58) kg. Each average daily gain, total body gain and initial body weight had not significant different in all groups. Correlation coefficient between SC, SH, blood serum testosterone concentration and final BW computed and ranged between (-0.397 to + 0.914).

Abstract. In a male anti-fertility study 7 volunteers received the anti-androgen cyproterone acetate (5 or 10 mg daily) orally in a paired study. A significant reduction in serum-cholesterol and LDL-cholesterol, and a significant increase in the intravenous-fat-tolerance-test (IVFTT) was observed. Thus low doses of cyproterone acetate reduced the serum testosterone concentration and some of the atherosclerotic risk factors.

The testosterone levels with nasal gland volume and Leydig cell morphometry in sexually mature capybaras were compared using 10 adult capybaras, aging 28 months. Body and testicular weight were 50kg and 28g, respectively. The gonadosomatic index was 0.11±0.02%, while nasal gland volume was 34.12±13.04ml. Serum testosterone concentration was 25.07±14.73ng/ml. Leydig cell volume density and leydigosomatic index were, respectively, 28.8±8.3% and 0.030±0.007%. Total and individual Leydig cell volumes were 6.88±1.92ml and 2,228.14±272.59x10-12ml, respectively. Leydig cell numbers per testis and per gram of testis were, respectively, 3,079.4±719.9x10(6) and 115.09±31.78x10(6) cells. These results show that increase in serum testosterone concentration is correlated to a proportional increase of nasal gland and Leydig cell volume in capybaras.

The Relationship

Blood samples were collected from five pregnant sows from day 111 postbreeding to farrowing and from their piglets at regular intervals between birth and 48 h. The time between birth and first suckling (BTS) was recorded for each piglet. Maternal serum testosterone (T) levels were detectable only at the beginning of parturition and were highly correlated (r = 0.83) with litter BTS. Serum T levels of male and female piglets were similar at birth. In male piglets the T levels increased to a peak 2 h after birth and decreased gradually thereafter. In contrast, the T levels of female piglets declined rapidly after birth to baseline levels. The BTS of female piglets was shorter than that of male piglets. Body weight of males was higher than that of females and was influenced by litter size. These results suggest that the higher serum T levels of male piglets may have a detrimental effect on their teat-seeking ability. Key words: Serum testosterone, sex, piglets, teat-seeking ability, sow

Peel Extract

The aim of the present study is to prepare ethanol extract of Pomegranate peel and the effects of this extract on testicular weight to body weight ratio, Serum cholesterol, testosterone concentration and histopathological changes of testes in rabbits treated with carbon tetrachloride (CCl4). Twenty four adult male rabbits were used. They were divided randomly into four equal groups. Animals were treated for 56 days as following: Rabbits of the 1st group were received 1 ml distal water orally once a day and olive oil 0.5 ml /kg B.W. I.P twice a week as control group. The second group were treated I.P with 500mg / kg B.W. of CCl4 mixing with equal volume of olive oil (0.5 ml/kg B.W.) twice a week (group T1). The third group was received pomegranate peel extract orally (100 mg/kg B.W) once a day and olive oil 0.5 ml /kg B.W. I.P twice a week (group T2). The fourth group were received pomegranate peel extract (100 mg/kg B.W) once a day oral I.P with 500 mg / kg B.W. of CCl4 mixing with equal volume of olive oil (o.5 ml/kg B.W.) twice a week (group T3). Blood samples were collected at (0, 14, 28, 42 and 56) days for measuring testosterone concentration, Serum cholesterol after treatments. Animals weighed and scarified and testis were removed and weighed, Samples of testis were taken for histopathological study. The results of the present study showed that treatment with pomegranate peel extract causes a significant (P>0.05) increase in testicular weight to body weight ratio. Also a significant (P>0.05) decreased of serum cholesterol and a significantly (P>0.05) elevation of testosterone concentration were observed. Histopathological examination of the testis was revealed that the extract of Pomegranate peel protect the testis against lesions caused by CCl4. In conclusion, Pomegranate peel extract could protect the tissue of testicles from CCl4 perhaps, by its anti-oxidative effect of pomegranate peel extract, hence eliminating the deleterious effects or toxic effect of CCl4.

SUMMARY Evaluation of the testis size is very important in stallions’ selection, since it is an indirect determinant of their reproductive potential. The aim of this study was to evaluate the biometric testicular traits, calculate the volume testicular and analyze the serum testosterone concentration of the stallion. During six months were measured the tests of adults Brazilian Ponies stallions from northern of Rio de Janeiro State, Brazil. The length, the width and the height of the testicles (TL, TW and TH) were measured. From these measurements, the total testicular volume (TTV) was calculated. The serum testosterone concentration was also evaluated. The data were studied by analysis of variance and were calculated the correlations among the traits. The average of the testis biometry were TL 5.8 ± 0.6 cm; TW 3.8 ± 0.5 cm; TH 4.7 ± 0.4 cm and 111.2 ± 27.7 for TTV. Mean of serum testosterone concentration was 0.89 ± 0.52 ng/dl. High correlations between biometry testicular traits with testicular volume were observed and low to moderate correlations were observed for testicular traits, testosterone and sperm output. The testis size could be an important trait that assists to the prediction of stallion's reproductive potential of the Brazilian ponies stallions. It is suggested that there would be no fluctuation in serum testosterone concentration in Brazilian ponies stallions that coult afect on its fertility.

The Impact

The objective of this study was to determine the effects of wood, cigarette and marijuana smoke on the reproductive health of tandoor occupants. A total of 100 male individuals were selected (50 control and 50 tandoor occupants). A standard questionnaire was designed regarding their age, economic status, marital status, fuel type, exposure time (per day), use of mask, addiction and reproductive health. Morning blood samples of 5 mL of the size were taken from all participants. Serums were obtained and analyzed for total serum testosterone concentration. Bio-check (USA) kit was used according to the manufacturer protocol and procedures for testosterone analysis. In control group the mean ± SEM of total serum testosterone was 671.9 ± 20.02 ng/dl where as in tandoor occupants it was 542.7 ± 16.40 ng/dl. There was a significant reduction (P**** < 0.0001) in total serum testosterone concentration in tandoor occupants as compared to control group. Reproductive health problems like, low libido, erection problems, infertility, decreased frequency for shaving and absent morning and nocturnal erection were common in tandoor occupants as compared to control group. Wood, cigarette and marijuana smoke negatively affects testosterone concentration and lowers it significantly. This reduced testosterone concentration then produces ill effects like low libido, erection problems, infertility and absent morning and nocturnal erection.
