Time trends, characteristics, and evidence of scientific advances within the legal complaints for alleged sexual HIV transmission in Spain: 1996-2012.
2014
This article quantifies and characterizes existing legal complaints for the sexual transmission of HIV in Spain, describes temporal trends and whether advance of scientific knowledge is reflected in charging decisions, judicial reasoning, and sentences. Sentences and writs dictated by Spanish penal and civil jurisdictions between 1981 and 2012 were obtained through legal databases systematic search. Sixteen sentences and 9 writs belonging to 19 cases were included; 17 judged by penal and two by civil jurisdictions. The first sentence was pronounced in 1996, 3 between 1999 and 2000, 4 between 2001 and 2005, and 18 between 2006 and 2012. In 10 (53%) cases there was effective HIV transmission,…
[Contraception in chronically ill adolescents].
2003
Contraception in chronically ill adolescents has to consider side effects with regard to metabolic or hematological disease. Additionally the compliance of the patient has to be taken in account when consulting about contraceptives. In juvenile diabetics with good glycemic control and metabolic diseases of the amino acids oral contraceptives are justifiable. Adolescents with galactose-mia mostly suffer from premature ovarian failure and therefore have to be controlled wether they need contraception at all. Young women with sickle-cell anemia are at risk of thrombophilia. They should not be given hormonal contraceptives. In v. Willebrand-Jurgens-Syndrome oral contraceptives are favourable be…
Studies on effects of tamoxifen (ICI 46474) on agonistic encounters between pairs of intact mice.
1988
The anti-estrogen tamoxifen (Tam), which has been shown to dramatically suppress offensive behavior in male rats without markedly influencing other aspects of the social encounter, was tested for its effectiveness in mice. TO strain albino mice were given control injections or 50 or 100 micrograms of Tam for 4 or 8 days. Subsequently, mice were tested in pairs (for a particular dose and treatment duration) in which both animals received Tam, one animal received Tam and one saline, or both animals received saline control injections. Ten-minute videotaped encounters were analyzed in terms of total times allocated to nonsocial investigation, social investigation, offense, defense, sexual activ…
Development and Retest Reliability of a German Version of the Sexual Behaviour Questionnaire (SBQ-G)
2007
A German version of the Sexual Behaviour Questionnaire (SBQ-G) is a short self-rating instrument covering the four domains of sexual function using colloquial words. Frequency of sexual dysfunction was counted and chance-corrected retest reliability was calculated. Eleven women and 12 men participated. Reception of the SBQ-G was favourable and more females than males reported at least moderate sexual dysfunction. Sexual arousal and ability to enjoy sex showed the lowest retest stability. The SBQ-G is a recommendable clinical instrument with high practicability and satisfactory retest reliability. However, gender differences and a high variability of sexual functioning in healthy subjects sh…
Effect of inhibiting carnitine biosynthesis on male rat sexual performance.
2008
l-carnitine has a documented role as a cofactor in cellular energy metabolism and fatty acid beta-oxidation pathways and it has also been considered to function in reproductive biology. We investigated whether decreasing concentrations of L-carnitine using an inhibitor of its biosynthesis, mildronate (3-(2,2,2-trimethylhydrazinium)-propionate), would influence the sexual behavior or sperm quality in male rats. Mildronate treatment induced a significant decrease in carnitine concentration and an increase in gamma-butyrobetaine (GBB) concentration in both plasma and testes extracts. However, the expression of carnitine palmitoyltransferase I in testes and testosterone concentration in plasma …
Mating Increases Neuronal Tyrosine Hydroxylase Expression and Selectively Gates Transmission of Male Chemosensory Information in Female Mice
2013
Exposure to chemosensory signals from unfamiliar males can terminate pregnancy in recently mated female mice. The number of tyrosine hydroxylase-positive neurons in the main olfactory bulb has been found to increase following mating and has been implicated in preventing male-induced pregnancy block during the post-implantation period. In contrast, pre-implantation pregnancy block is mediated by the vomeronasal system, and is thought to be prevented by selective inhibition of the mate's pregnancy blocking chemosignals, at the level of the accessory olfactory bulb. The objectives of this study were firstly to identify the level of the vomeronasal pathway at which selective inhibition of the m…
Epidemiology of sexual dysfunction in the male population.
2006
Sexual dysfunctions have found an increasing attention in recent epidemiological studies of the ageing male. The purpose of this paper is to review the prevalence of sexual dysfunctions and risk factors based on community samples. Studies have not only demonstrated a strong age-related incline of erectile dysfunction (ED), but also of ejaculatory and orgasmic disorders (particularly a reduced or absent ejaculation). Despite a declining sexual desire, sexual interest remains present in old age. Lower urinary tract symptoms have been identified as strong risk factors for ED along with cardiovascular, metabolic, psychiatric disorders and lifestyle factors. The wide range of prevalence rate est…
Do women have a hidden heat period?
2002
This article aims to throw light on the controversial topic of whether women have a 'heat' period within their menstrual cycle. The majority of publications in this field report, in addition to a periovulatory peak, no changes at all or even rises in male- and female-initiated sexual activity, woman's sexual desire, autosexual activity and sexual arousability, and interpersonal sexual activities during the mid-follicular and late luteal phases. The lack of a distinct pattern of women's sexual behaviour across the menstrual cycle may be explained by the interplay between cyclical endocrine fluctuations and many psychological, social, cultural and environmental factors, as well as the methodo…
Urinary and sexual outcomes in long-term (5+ years) prostate cancer disease free survivors after radical prostatectomy.
2009
Abstract Background After long term disease free follow up (FUp) patients reconsider quality of life (QOL) outcomes. Aim of this study is assess QoL in prostate cancer patients who are disease-free at least 5 years after radical prostatectomy (RP). Methods 367 patients treated with RP for clinically localized pCa, without biochemical failure (PSA ≤ 0.2 ng/mL) at the follow up ≥ 5 years were recruited. Urinary (UF) and Sexual Function (SF), Urinary (UB) and Sexual Bother (SB) were assessed by using UCLA-PCI questionnaire. UF, UB, SF and SB were analyzed according to: treatment timing (age at time of RP, FUp duration, age at time of FUp), tumor characteristics (preoperative PSA, TNM stage, pa…
Gonadotropin Hormone Modulation of Testosterone, Immune Function, Performance, and Behavioral Trade‐Offs among Male Morphs of the Lizard Uta stansbur…
2008
Sexual selection predicts that trade-offs maintain trait variation in alternative reproductive strategies. Experiments often focus on testosterone (T), but the gonadotropins follicle-stimulating hormone and luteinizing hormone may provide a clearer understanding of the pleiotropic relationships among traits. We assess the activational role of gonadotropins on T and corticosterone regulation in traits expressed by polymorphic male side-blotched lizards Uta stansburiana. Gonadotropins are found to enhance and suppress multiple physiological, morphological, and behavioral traits independently, as well as indirectly via T, and we demonstrate selective trade-offs between reproduction and surviva…
