The sexual genogram explained

A sexual genogram is a genogram that adds what each generation learned and said about sex, gender and intimacy to the usual record of a family. Larry Hof and Ellen Berman described it in 1986 for couple and sex therapy. This guide explains its terms, what it records and why, and the rules on consent and anonymity, with a fictional chart drawn in the editor.

A fictional sexual genogram of the Calder and Moreau families. Nina, the index person, and Theo are joined by the double line of a committed relationship. Under several names a Messages field reads Sex plus, Sex minus or Sex zero, and an Identity field reads L, B or H. Ruth carries a red triangle for a secret, a cutoff repaired line runs from Ruth to her daughter Helen, and green arrows named Sex education run from Helen to Nina and from Anne to Theo.

A sexual genogram adds messages about sex to a family genogram

The drawing is an ordinary genogram. Belous and colleagues, who revisited the method in 2012, describe it as structurally no different from a traditional genogram, with a further layer about sex and sexuality. That layer records what each person was told, what was never said, how affection was shown and how each person describes their gender and attraction.

Hof and Berman wrote for therapists treating couples. Belous and colleagues extended the method to individual clients, and their paper appears as course material on a sexuality counselling course at East Carolina University.

Draw the chart with identity marks and fields of your own

Record identity in the person’s own words, and turn on Clinical mode before you export.

  • Opens without an account
  • LGBTQIA, transgender and secret marks
  • Clinical mode replaces names with numbers in exports

Hof and Berman build the chart in five steps

Belous and colleagues summarise the original method in five steps. The questions of the third step can be answered at home or in the session, and the genogram interview questions cover the family history of the first two.

  1. Introduce the genogram

    Explain to the client or couple what a genogram is.

  2. Draw the family

    Draw the standard genogram and talk through what it shows.

  3. Add the sexual layer

    Ask the questions on sex and intimacy for each generation.

  4. Discuss the chart

    Talk about the patterns the finished chart displays.

  5. Plan the treatment

    Bring what the chart shows into the plan for the therapy.

The five steps of Hof and Berman (1986), as Belous and colleagues (2012) summarise them.

Six areas of questions decide what goes on the chart

The third step asks about six areas, each linking what the family passed down with what the client or couple brings now. That link is why the chart records these things and leaves the rest out.

AreaWhat it asks aboutOn the teaching chart
MessagesWhat each generation said or implied about sex, intimacy and being a man or a womanSex +, Sex − or Sex Ø under a name
CommunicationHow the family talked about sex and showed affectionGreen arrows from the adults who answered questions
SecretsWhat the family kept quietThe red triangle beside Ruth
Missing informationWhat is unknown and how it might be found outNo identity for Mari, who was not asked
The partner’s viewWhat each partner notices in the other’s chartThe Moreau side, drawn by Theo
Wishes for changeWhat the person or couple want to changeKept in the notes
Hof and Berman’s six areas, as Belous and colleagues (2012) list them.

The 2012 update records identity in the person’s own words

Belous and colleagues give every person an orientation or attraction, written as a letter the person chose, such as L for lesbian, G for gay, B for bisexual, P for pansexual, Q for queer or questioning, A for asexual and H for heterosexual. The letters record how people describe themselves, never what the therapist assumes.

The editor draws the inverted triangle of McGoldrick, Gerson and Petry (2020) instead, and the teaching chart shows both. Mari, Helen’s wife, has neither, because she was not asked, and a partner’s gender does not answer the question.

TermWhat it meansOn the teaching chart
Sex +Open and accurate information at the right ageHelen and Anne
Sex −Fear based messages and little informationGraham and Ruth
Sex ØThe subject never came upIan, Clare and Luc
Family boundaryA dashed circle around an open family and a solid one around a closed familyTwo households named for how each home talked about sex
Committed relationshipA solid line for any relationship the couple calls committedNina and Theo, on the editor’s committed line
Sexual history timelineThe events that shaped the person, on a line under the chartNot drawn, because the client decides whether to share it
Terms from Belous and colleagues (2012), with how the teaching chart shows each one.

The teaching chart follows two fictional families

Nina Calder, the index person, and Theo Moreau are in couple therapy because they find it hard to talk about intimacy. Nina’s grandparents treated sex as a risk to avoid until marriage. Ruth was pregnant with Ian when she married Graham in 1968, a secret the family kept, and she stopped speaking to Helen for four years after Helen came out in 1995.

Ian and Clare left the subject to a book, and Nina’s aunt Helen answered her questions. On Theo’s side, Anne answered questions as they came and Luc left the room. Each partner brings a different family habit to the same difficulty, which is the comparison the fifth area of questions invites.

Draw a sexual genogram in the editor with marks and fields

Draw the family first. Then select a person, open Identity and marks, type the person’s own words in Gender identity, and switch on LGBTQIA or Secret where they apply.

For the sexual layer, click Add a field under Notes and name it Messages or Identity, so that the value is written under the name. A custom line records who answered a child’s questions, and the Clinical switch in the bottom strip replaces the names with numbers.

Common questions

Whether a sexual genogram is explicit

It need not be. It records messages, identities and secrets, and the detail of any experience stays in the conversation.

Whether students must draw their own family

No. Under the ACA code, students decide what they share in class, and a course can accept a fictional or volunteer family. Ask the instructor before you start.

Who may see the finished chart

Only the people the person has agreed to show it to. In a course that is usually the instructor alone.
