Review
Bull libido, or sex drive, is a measurable trait with a large genetic component. It also represents an important aspect of bull reproductive performance, with positive effects on herd pregnancy rates and their patterns. Comparative, quantitative assessment of this trait requires a formalized testing procedure such as a test for libido or serving capacity score. Such tests are useful not only for obtaining quantitative information, but also for the detection of physical and pathologic problems that may interfere with normal bull mating ability. These tests should be conducted in such a manner that animal welfare is not unnecessarily compromised. The quantitative results should be interpreted with caution, especially when young, inexperienced bulls or those of Bos indicus breeds are being assessed. Libido does not necessarily work in concert with other traits known to separately influence bull fertility (e.g., BSE traits and social dominance). Until a single procedure is found that can adequately assess all of these factors, optimal bull appraisal requires separate evaluation of each of these factors.

Review
This article is part of a Special Issue "Puberty and Adolescence". Sexuality emerges as a major developmental element of puberty and the adolescent years that follow. However, connecting the sexuality that emerges with puberty and elements of adult sexuality is difficult because much adolescent sexuality research addresses the transition to partnered sexual behaviors (primarily coitus) and consequences such as unplanned pregnancy and sexually transmitted infections. This review proposes a framework of an expanded understanding of puberty and adolescent sexuality from the perspective of four hallmarks of adult sexuality: sexual desire; sexual arousal; sexual behaviors; and, sexual function. This approach thus addresses important gaps in understanding of the ontogeny of sex and the continuum of sexuality development from adolescence through the adult lifespan.

Review
OBJECTIVE
The aim of this review was to summarize the literature regarding the potential role of testosterone therapy for women.
METHODS
The author conducted a search of the literature using Medline (Ovid, 1946-present) and PubMed (1966-2013) for English-language studies that included the following search terms: 'testosterone' or 'androgen' combined with 'women', 'therapy' or 'treatment'.
RESULTS
Randomized, placebo-controlled trials have consistently shown that transdermal testosterone therapy improves sexual desire, arousal, orgasm frequency and satisfaction in premenopausal and postmenopausal women presenting with sexual desire/arousal problems. No adverse metabolic effects have been observed in these studies. In postmenopausal women, testosterone therapy has also been associated with favorable effects on body composition, bone, cardiovascular function and cognitive performance.
CONCLUSIONS
Although androgens have many varied roles, the focus of testosterone therapy for women has been on improving sexual desire. Not only do testosterone effects on sexuality extend beyond libido, but testosterone has other key physiological actions. Issues that urgently need to be addressed include approval of a testosterone formulation that delivers a female dose such that physicians refrain from prescribing compounded testosterone or modifying doses of testosterone formulated for men and regulation of prescription of compounded androgens for women.

Review
The effects of steroidal hormones on sexual desire and motivation are a question still under debate. This paper reviews up-to-date knowledge regarding physiological imprinting and activation by endogenous hormones of central nervous system areas involved in libido during intrauterine life and puberty. The endocrine environment probably continues to play a role during fertile life and the postmenopausal period, but this effect is often overridden by psychological and social factors. The impairment of sexual interest during estrogen-progestin treatment is an infrequent but relevant side-effect whose possible underlying mechanisms are discussed. Both endocrine and psychorelational elements may interact. From the biological point of view, androgen and oxytocin level modification and loss of estrogen fluctuations have been considered, but also the history of hormone-related mood changes could be a risk factor. On the psychological side, both the profound repercussions of the contraceptive choice and consequent responsibility, as well as the high value attributed to sexual experience are probably facilitating elements in the loss of libido under treatment.

Review
Women with an androgen deficiency complain about a loss of libido and a lack of well-being. It is difficult to link these symptoms to low circulating androgen levels in blood. This is because these complaints often arise during a period of life characterized by major psychosocial changes. Furthermore, coinciding oestrogen deficiency may give rise to similar symptoms. Another problem is the assessment of androgen deficiency. The androgen assay used is designed for men presenting with levels much higher than normal. Finally, concentrations in the peripheral blood are a poor reflection of intracellular androgen receptor stimulation. Patients with complaints suggestive of a relative androgen deficiency (based on the pattern of complaints and low serum androgen concentrations) should first of all be counselled for psychosocial problems. Oestrogen deficiency should subsequently be ruled out or substituted. If the complaints still persist then androgen substitution can be considered.

OBJECTIVES
The objectives of this study were to investigate the relationship between a low libido and objective sleep parameters as well as mood disturbances in patients with obstructive sleep apnea syndrome (OSA).
METHODS
We enrolled 436 untreated patients who were newly diagnosed with OSA (all male, mean age 42.8 years). Patients completed the Symptom checklist-90-Revised (SCL-90-R), Epworth Sleepiness Scale (ESS), Beck Depression Inventory-II (BDI), and Beck Anxiety Inventory (BAI). Patients were divided into low-libido and normal-libido groups according to their response to the statement "Loss of sexual interest or pleasure" on the SCL-90-R.
RESULTS
Approximately 23% of patients reported a low libido. Patients with a low libido were older (47.5 ± 9.0 vs. 41.4 ± 11.1 years; p < 0.001), had more nocturia (33.3% vs. 16.6%; p < 0.001), higher BDI (9.0 (5.0-14.0) vs. 5.0 (2.0-9.0); p < 0.001) and BAI score (11.0 (6.3-16.8) vs. 5.0 (2.0-10.0); p < 0.001). These patients had a lower non-REM sleep stage 3 (N3) % (0.1 (0-4.0) vs. 2.3 (0.1-7.9); p < 0.001). Multivariate analysis revealed that older age and higher BDI score were independent factors associated with a low libido.
CONCLUSIONS
Men with untreated OSA suffered from a low libido. Older age and depressed mood were the most important factors of low libido in middle-aged men with OSA.
