While most studies on sexuality in later life report that sexual desire declines with age, little is known about the exact nature of age effects on sexual desire. Using self-reported dyadic sexual desire relating to a partner, dyadic sexual desire relating to an attractive person, and solitary sexual desire from a large (N > 8000) and age diverse (14.6-80.2 years) online sample, the current study had three goals: First, we investigated relationships between men and women's sexual desire and age. Second, we examined whether individual differences such as gender/sex, sexual orientation, self-rated masculinity, relationship status, self-rated attractiveness, and self-rated health predict sexual desire. Third, we examined how these associations differed across sexual desire facets. On average, the associations between age and both men and women's sexual desire followed nonlinear trends and differed between genders/sexes and types of sexual desire. Average levels of all types of sexual desire were generally higher in men. Dyadic sexual desire related positively to self-rated masculinity and having a romantic partner and solitary desire was higher in people with same-sex attraction. We discuss the results in the context of the evolutionary hypothesis that predict an increase of sexual desire and female reproductive effort prior to declining fertility. Our findings both support and challenge beliefs about gender/sex specificity of age effects on sexual desire and highlight the importance of differentiating between desire types.

Testosterone is a natural hormone which is an essential factor to maintain the physical and emotional well-being in men, regardless of age. Male hypogonadism is an endocrinal condition of testosterone deficiency with the potential to cause multiple physical complaints and psychosocial problems. The condition can be of primary (due to testicular injury), secondary (due to diseases of the hypothalamus or pituitary gland) or functional nature (due to comorbidities, such as inflammatory diseases, obesity, type 2 diabetes mellitus).

This review focuses on bull breeding behaviors and management strategies to improve reproductive efficiency. Breeding soundness evaluations are utilized to classify a bull's physical ability and sperm quality, yet roughly 20 % of bulls fail to meet the minimum criteria. Furthermore, despite achieving the minimum criteria, few bulls in multi-sire breeding groups sire the majority of calves, indicating a need for better understanding of bull behavior that impact siring capacity, and thus, a bull's reproductive efficiency.

Sexual boredom in women is associated with various levels and dimensions of sexual desire, as well as lower sexual and relationship satisfaction. However, the directionality of these relationships remains unclear. This study aimed to investigate whether sexual boredom mediates the relationship between partner and attractive-other sexual desire and sexual and relationship satisfaction in a sample of 1155 Portuguese women in long-term monogamous relationships.
