Hertlein, Katherine, Gerald R. Weeks & Nancy Gambescia. Systemic Sex Therapy. Routledge 2015 (2nd edn). Paperback, condition near-Fine, laminated protection very slightly lifted on edges of back cover. This comprehensive textbook, intended for graduate students in couple and family therapy programs as well as for clinicians of diverse orientations, offers descriptive discussions of sex therapy based on the Intersystem Approach, as developed by Gerald Weeks. The Intersystem Approach considers the biology, psychology, couple dyad, family-of-origin, and larger contextual factors of any sexual disorder or issue. It is grounded in systems theory and represents a new understanding of human sexuality and sexual problems. Appropriate for anyone who wants to progress to a more comprehensive and integrative understanding of sexual dysfunctions, this text will teach the reader how to treat the couple, rather than the individual. The second edition includes 12 updated chapters and two new chapters.
