Analysis of characteristics of patients with introital central dyspareunia. Is late coitarche (age at first sexual intercourse) a risk factor for introital dyspareunia?
145 women attending a vulvo-vaginitis clinic in secondary and tertiary care center in Tienen and Leuven, Belgium, with central introital pain during sexual intercourse.
The mean age of the study group was 32 years, and 5% were 60 years of age or older. Of the patients, 51% had primary and 49% secondary dyspareunia. Before referral, two-thirds of the patients had already tried several types of therapy, including psychiatric help in 16% of cases. The study group of patients with central introital dyspareunia had a coitarche at a mean of 18.3 years. 72% of the dyspareunic women with coitarche later than 18 had to regularly interrupt intercourse because of pain, compared with 52% of women with coitarche before 18 (p<0.05). A strong correlation was found between the age of sexual debut and the necessity to interrupt intercourse attempts due to pain (p<0.001). Frequency of intercourse was also found to be inversely related to coitarche.
Women with introital dyspareunia had their sexual debut at a later age than otherwise comparable women. Late coitarche is inversely related to frequency of attempted intercourse and to the necessity to interrupt intercourse due to pain, suggesting a relation between coitarchal age and severity of dyspareunia. A possible explanation is increased fibrosis and stiffening of the hymenal remnants at the posterior vulvar commissural due to increasing age in primary, and repeated injury by sexual contacts in secondary, central introital dyspareunia patients.
分析阴道入口中央性交疼痛患者的特征。初次性交年龄（初次性行为年龄）是否为阴道入口性交疼痛的危险因素？
比利时蒂嫩和鲁汶二级和三级保健中心的阴道-外阴炎症门诊共招募了 145 名患有中央阴道入口性交疼痛的女性患者。
研究组的平均年龄为 32 岁，5%的患者年龄在 60 岁或以上。其中 51%的患者为原发性性交疼痛，49%的患者为继发性性交疼痛。在转诊之前，三分之二的患者已经尝试了多种类型的治疗，包括 16%的患者接受了精神科帮助。在患有中央阴道入口性交疼痛的患者中，初次性交的平均年龄为 18.3 岁。与 18 岁前初次性交的女性（52%）相比，性交疼痛后需要经常中断性交的性交疼痛患者中，初次性交年龄大于 18 岁的比例更高（72%）（p<0.05）。性初潮年龄与因疼痛中断性交尝试的必要性之间存在很强的相关性（p<0.001）。同时发现性交频率与初潮年龄呈负相关。
患有阴道入口性交疼痛的女性与其他可比女性相比，初次性交年龄较晚。初次性交年龄与尝试性交的频率以及因疼痛中断性交的必要性呈负相关，表明初潮年龄与性交疼痛的严重程度之间存在关联。一个可能的解释是，原发性阴道入口中央性交疼痛患者的处女膜残端在后外阴联合处的纤维组织不断增加和变硬，而继发性阴道入口中央性交疼痛患者的处女膜残端则由于性接触的反复损伤而变硬。
