Maladaptive defense mechanisms are associated with decoupling of testosterone from sexual desire in women of reproductive age

Interoceptive Awareness, Alexithymia, and Sexual Function

Research in women suggests a relation between sexual difficulties and lower interoceptive awareness, the conscious perception of internal bodily states. Lower interoceptive awareness is theoretically linked to greater alexithymia, which has been related to sexual dysfunctions. Hence, we examined the relations of interoceptive awareness and alexithymia with several dimensions of sexual functioning in a nonclinical sample of both sexes. Methods: Three hundred forty Portuguese (228 women, 112 men) completed the Toronto Alexithymia Scale (TAS-20) and the Multidimensional Assessment of Interoceptive Awareness (MAIA). Women additionally completed the Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale-Revised (FSDS-R). Men additionally completed the International Index of Erectile Function (IIEF) and one question on difficulties delaying ejaculation. Greater alexithymia correlated with lesser interoceptive awareness. For women, greater alexithymia and lesser interoceptive awareness correlated with lesser arousal, lesser lubrication, more orgasm difficulties, more dissatisfaction, more pain, and more sexual distress. Higher female desire correlated with greater interoceptive awareness, but was unrelated to alexithymia. In men, lesser interoceptive awareness correlated with more difficulties delaying ejaculation, and greater alexithymia correlated with more erectile difficulties. The present investigation corroborates that awareness of emotions and internal bodily states is important for sexual functioning.

Poorer Subjective Sleep Quality Is Related to Higher Fantasy-Induced Sexual Arousal in Women of Reproductive Age

Lack of sleep enhances erections and lubrication the next day. This raises the possibility that poorer subjective sleep quality is related to sexual arousal. To test this hypothesis, sexual arousal was elicited in 70 Portuguese women of reproductive age by means of fantasy. The level of salivary testosterone before and shortly after fantasy was determined by luminescence immunoassays. Participants completed the Pittsburgh Sleep Quality Index (PSQI), reported their sexual arousal before and during fantasy, and how anxious they were after the fantasy. The hypothesis was confirmed. Anxiety did not explain the association, but testosterone response (poststimulus minus baseline) had a slight explanatory effect.
