  原标题:25岁美女老师原是“纯爷们”

  有着萝莉的面孔、魔鬼的身材,十余年不来例假,一直被诊断为“原发性闭经”,如果不是要结婚考虑要小孩,25岁的小张怎么也想不到,自己居然是染色体为46XY的“纯爷们”。

  小张是荆门一学校老师,良好的文化修养和外形条件,身边追求者众多。惟一让她烦心的是,自己25岁了,却从没例假。在当地医院检查,一直认为是“原发性闭经”。直到最近,家里催促她结婚,考虑到婚后要小孩的事情,她决定到武汉来查。

  今年10月,小张到武汉大学[微博]人民医院,B超检查结果让她大吃一惊,她居然没有子宫,卵巢也呈多囊性改变,且腹部有两个球状阴影,考虑为隐睾。进一步做性激素和染色体检查,显示其睾酮增高,染色体核型分析为46XY。从生物学上说,“她”就是一名男性!

  既然染色体注定其为男性,为何没有喉结和男性生殖器,反而阴道卵巢俱在、且外在表象都是女人呢?

  该院整形外科王松山教授解释,张“小姐”的情况在医学上称为两性畸形,即体内同时具有睾丸与卵巢这区分男女的双重性腺。张“小姐”的盆腔双侧虽有隐睾且睾酮偏高,但机体对雄激素并不敏感,卵巢的存在却制造了轻微的雌激素,使得从遗传生理学上被鉴定为男性的“她”,在生理外观上的女性化特征严重,也就是常说的“男身女相”。

  据介绍,所谓“两性人”即两性畸形,是指体内同时保留男女两套生殖系统,该病发病率极低。双性畸形来源于胚胎期发育异常,有的是因为遗传因素,有的是因为孕期外界感染。两性畸形可分假性和真性。假性分为两种,如果体内有卵巢,但没有睾丸,则属于女性假两性畸形;反之则属于男性假两性畸形。而像张“小姐”这样体内同时存在睾丸和卵巢的,则属于真性两性畸形。

  上月20日,医生给小张做了腹腔镜双侧盆腔肿物切除术。术后病检结果显示,这是两个分化不良的睾丸组织。

  术后,张“小姐”恢复良好,性激素睾酮下降正常,昨天已痊愈出院。

  医生表示,由于先天性无子宫,加之卵巢发育不良,张“小姐”不能生育,但由于具备阴道组织,“她”可过正常夫妻生活。

  并不是所有的两性畸形患者都无法生育。王松山表示,很多真两性畸形患者由于性腺发育良好,子宫卵巢俱在且睾丸发育良好,即便不通过手术矫正,其生育的几率也高达70%~80%。曾有国外文献报道,有一位真两性畸形患者,由于男女两套器官健全,先后组成过两个家庭,分别作为丈夫和妻子生育了两个孩子。

  而女性假两性畸形且术后“定性”为女性患者,生育率和治疗时间密切相关。若子宫发育良好且2岁之前就已接受治疗,生育率可达40%;拖得越久,生育率越低,18岁之后便会下降为1%。(来源:武汉晨报)

  A 25-year-old woman in Hubei Province was found to be genetically a man after she was examined at a Wuhan hospital to find out why she never menstruated, a local newspaper reported。

  The woman, surnamed Zhang, a teacher in Jingmen City, was reported to be very attractive with many men interested in dating her. But she never had a period and was previously diagnosed at a local hospital to have an abnormal absence of menstruation。

  Zhang decided to get a second opinion as her relatives were worried she wouldn't be able to get pregnant when she gets married, according to Wuhan Morning Post。

  Last month, Wuhan University People's Hospital stunned Zhang, telling her an ultrasound showed she had a vagina but no womb. The examination also found two shadows in her abdomen that were believed to be undescended testicles, the newspaper said. The reason she never had a period is because she is actually a man according to her chromosomes, as tests showed, the newspaper said。

  Wang Songshan, a medical professor with the hospital, told the newspaper that Zhang is a hermaphrodite with both testicles and ovaries. A hermaphrodite has reproductive organs normally associated with both male and female sexes。

  Although she looks like a woman, her genetics tell a different story, Wang told the newspaper。

  Zhang had surgery on October 20 to remove her testicles. Doctors said that Zhang could still have normal sexual relations but she could not give birth to a child。(来源:Shanghai Daily)
