The purpose of the present study was the pathological analysis of childhood masturbation. According to our results, 10.8% of participants had pathological masturbation.
The children stimulated their genitals more commonly by hand, rubbing the genitalia against other objects and water pressure. The less common ways of masturbation included masturbating while wearing tights, knocking genital to wall, sleeping on stomach and genitalia, rhythmic contraction, and relaxation of thigh muscles. This finding is consistent with previous studies (
10-
14), even though the studies are somewhat different. In the present study, our subjects were in the age range of 2 - 12 years; however, most previous studies were about infantile self-stimulation. For example, Hansen and Balslev (
10) reported some distinct patterns of hand activities in infantile masturbation, including grasping of toys, furniture or clothing, chorea-like “piano playing” hand movements, pressure over the diaper/genital region, and bimanual manipulation of items.
Other features of masturbation in infants were unusual apparent dystonia (
11), rocking and adducting thighs (
12), sitting with legs crossed over, rhythmic contraction and relaxation of thigh muscles accompanied by pelvis rocking movements (
13), stiffening legs and made rubbing motions, and stereotypical movements when sitting (
14).
Episodes of masturbation accompanied by distance and withdrawal (
14), grunting, scratching or squeezing chest and staring (
11,
14), irregular breathing (
12,
13), tongue licking, lip-smacking, eye-rolling, and shakiness (
11,
12), facial flushing (
13,
14) diaphoresis (
11,
13), pallor and giggling (
11). Masturbation did not involve genital manipulation with hand in none of the mentioned studies (
10-
14).
In our study, 33.84% of children were reported to masturbate most of the time. Others masturbated when they were exited, agitated, bored, afraid, anxious, or tired. Some case reports showed that infants masturbated when they were upset (
12) angry, anxious (
15), or stressed (
14).
Childhood masturbation is sometimes a mechanism to cope with negative emotions and the children attempt to comfort themselves by masturbation when they are stressed about something (
2). Our findings indicated that 76.88% of children with pathological masturbation have comorbid psychiatric disorders, including ADHD, anxiety, communication disorder, LD, tic, OCD, mood disorder, and MR. Unal found that 52% of samples with childhood masturbation have comorbid disorders, including Oppositional Defiant Disorder (ODD), ADHD, pica, encopresis, nocturnal enuresis, sleep disorder, and conduct disorder (
16). This difference between two studies may be due to different definitions of pathological masturbation, features of subjects, or methodological differences in the diagnosis of psychiatric disorder.
Schoentjes et al. reported that internalizing and externalizing behavior scores on the Child Behavior Checklist (CBCL) is significantly associated with sexual behavior. Children with serious behavioral and emotional problems tent to show a broader range of behaviors, including excessive sexual behavior on the CBCL (
9). It is also probable that, comorbidity of psychiatric disorders in children, prevent the effective parenting by parents.
Some children masturbated when they were bored or alone. This is consistent with the studies described self-stimulation in children with a severe lack of external stimulation (
8,
17). The most common situations in which children are likely to masturbate included in front of the television, in the toilet, and bed. In the study conducted by Nechay et al. (2004), masturbation occurred in any situation in some children. The car seat was the most common specific location followed by sleeping, boredom, watching television, and being in a baby walker. The least common situations were lying on the floor, being in the high chair, and during nappy changing (
11).
In our study, self-stimulation started in one girl after urethral infection, which confirms that local irritation in the genital area can initiate or maintain masturbation (
18). Vulvovaginitis, urinary tract infections, or dermatitis cause perineal discomfort and may exacerbate the masturbatory behavior but may also be the result of the behavior. In these cases, an exact genital examination should be performed, and medical therapy should be performed if need be (
19).
One boy started to masturbate after constipation, failure to control bowel, and anal surgery. Unal also reported that 36.1% of children started to stimulate their genitals after a genitourinary disease, such as urethral infection, parasitic disease, or nappy dermatitis (
2).
One girl started to masturbate after watching a porn movie. In this regard, sexual behavior was found to be associated with parental attitudes toward sexuality (
20,
21). It has been reported that more explicitness, honesty, and disclosure about this issue in the family are related to more sexual behaviors in children (
20,
21). In terms of gender differences, our findings indicated that the number of girls who were brought in was more than boys (55.4% versus 44.6%). Girls also were the subject of reports more frequently (
10,
12-
15). These sex differences could be due to the anatomical differences or social and cultural factors (
2,
15).
In the current study, most of the children’s mothers had bachelor’s degrees (the highest educational level in this sample). The finding was similar to previously published studies, finding the sexual behavior was related to maternal education (
9,
20). Educated mothers probably felt more comfortable with report their children’ sexual behavior or probably because they were more observant of their children (
20).
In conclusion, low awareness of specialists can cause anxiety in parents and unnecessary examinations on children. Correct diagnosis of childhood masturbation could happen by awareness, a precise history, and watching a video of the behavior.
Awareness about this problem, its behavioral patterns, the situations in which masturbation occurs, and its comorbid disorders can facilitate the diagnosis of the problem and prevent the unnecessary tests and treatments. Physical examination is important because local irritation in the genital area could be involved in the initiation or continued masturbating.
5.1. Limitations
The subjects were selected by convenience sampling; therefore, the findings should be generalized to other groups with caution.
