45,X/46,XY mosaicism is a rare anomaly in sexual differentiation, presenting with diverse phenotypes and often leading to infertility due to abnormal gonadal development.
This report aims to present a case study of a 45,X/46,XY mosaic male patient with an ejaculatory disorder attributed to seminal vesicle dysplasia.
In this case study, diagnostic procedures encompassed blood tests, semen analysis, chromosomal examination, and imaging studies to assess gonadal morphology. Treatment strategies included attempted varicocelectomy, pharmacological intervention with amoxapine, and surgical testicular sperm extraction. Additionally, the patient underwent assisted reproductive techniques, specifically intracytoplasmic sperm injection (ICSI), to facilitate pregnancy for his wife.
A 32-year-old man could not ejaculate, with post-orgasmic urinalysis revealing minimal sperm presence. Chromosomal analysis confirmed 45,X/46,XY mosaicism. Despite undergoing microsurgical varicocelectomy for clinical varicocele and receiving tricyclic antidepressants, no improvement in semen volume occurred. Imaging studies indicated ejaculatory disorder due to prostate and seminal vesicle aplasia. Consequently, surgical retrieval of testicular sperm was performed, leading to successful pregnancy via ICSI for his wife.
Our approach has effectively addressed ejaculatory disorder in 45,X/46,XY mosaic men, resulting in successful pregnancy.
45,X/46,XY嵌合体是性分化中一种罕见的异常情况,表现出多种表型,常因性腺发育异常导致不育。
本报告旨在介绍一例45,X/46,XY嵌合男性患者的病例研究,该患者患有射精障碍,病因是精囊发育不良。
在本病例研究中,诊断程序包括血液检查、精液分析、染色体检查和影像学研究以评估性腺形态。治疗策略包括尝试进行精索静脉曲张切除术、使用阿莫沙平进行药物干预以及手术取睾丸精子。此外,患者接受了辅助生殖技术,特别是卵胞浆内单精子注射(ICSI),以帮助其妻子受孕。
一名32岁男性无法射精,性高潮后尿液分析显示精子极少。染色体分析证实为45,X/46,XY嵌合体。尽管因临床精索静脉曲张接受了显微精索静脉曲张切除术并服用了三环类抗抑郁药,但精液量没有改善。影像学研究表明射精障碍是由于前列腺和精囊发育不全所致。因此,进行了手术取睾丸精子,通过ICSI使其妻子成功受孕。
我们的方法有效解决了45,X/46,XY嵌合男性的射精障碍问题,实现了成功受孕。
