Triple A syndrome, caused by autosomal recessively inherited mutations in the gene is characterized by alacrima, achalasia, adrenal insufficiency, and neurological impairment. To the best of our knowledge, no patients of both sexes have been reported to have offspring. Our aim was to assess the causes of infertility in male patients with this multisystemic syndrome, and to present a female patient that spontaneously conceived a child.
Cross-sectional study.
Six males aged 19-48 years were included. Gonadotropins, testosterone, DHEAS, androstenedione, inhibin B, anti-Mullerian hormone measurements and testicular ultrasound were performed.
All six male patients had impaired general health and neurological symptoms including erectile and ejaculatory dysfunction. None of them had an offspring. The only demonstrated cause of infertility in our male patients was erectile and ejaculatory dysfunction which precludes sexual intercourse. Our patients had normal libido but were sexually abstinent. Except for low adrenal androgen levels, the concentrations of all measured hormones as well as testicular ultrasound were normal which may indicate the possibility of spermatogenesis in male patients with triple A syndrome. Little is known about fertility in female patients, but based on our observations spontaneous pregnancies seem to be possible.
Our results contribute to still scarce knowledge on fertility in patients with Triple A syndrome and as well represents a foundation for further research on causes of infertility and possible treatment options.
三 A 综合征是由常染色体隐性遗传突变引起的,其特征为无泪、食管失弛缓症、肾上腺功能不全和神经损伤。据我们所知,尚未报道两性患者有后代。我们的目的是评估患有这种多系统综合征的男性患者不孕的原因,并介绍一位自然受孕的女性患者。
横断面研究。
纳入 6 名年龄在 19-48 岁的男性。进行了促性腺激素、睾酮、DHEAS、雄烯二酮、抑制素 B、抗苗勒管激素测量和睾丸超声检查。
所有 6 名男性患者均存在全身健康和神经症状,包括勃起和射精功能障碍。他们均无子女。我们的男性患者唯一表现出的不孕原因是勃起和射精功能障碍,这会妨碍性行为。他们的性欲正常,但禁欲。除了肾上腺雄激素水平低外,所有测量激素的浓度以及睾丸超声均正常,这可能表明三 A 综合征男性患者存在精子发生的可能性。女性患者的生育能力知之甚少,但根据我们的观察,自然妊娠似乎是可能的。
我们的结果有助于进一步了解三 A 综合征患者的生育能力,并为进一步研究不孕原因和可能的治疗选择提供基础。
