Abstract

Globozoospermia is a rare (incidence <0.1%) and very severe disorder, with major implications in male fertility. Total globozoospermia is represented by the presence of spermatozoa with 100% rounded heads and a lack of acrosomes. These specific morphological modifications seem to be connected to defects occurring in the last stage of spermatogenesis, spermiogenesis, and will result in anomalies of the acrosomal reaction and a defective adherence of the spermatozoa to the oocytes zona pellucida. This will result in a failure of natural fertilization. This article aims to present the case of a couple diagnosed and successfully treated for primary male infertility. The 26-year-old male partner underwent two semen analyses that revealed the presence of fully rounded spermatozoa heads (morphological abnormality) and consequently was proposed for in vitro fertilization treatment. Semen preparation and the use of assisted reproductive techniques, intracytoplasmic injection of sperm cells into the assisted oocyte activation, have resulted in the conceivement of a healthy child. The particularities of this case lie in the early recognition of the total abnormal globozoospermia morphology. This is the first case reported in Romania where specific assisted reproductive techniques and treatments have resulted in a successful pregnancy for a couple with male total globozoospermia.

摘要

全球精症是一种罕见的(发病率<0.1%)且非常严重的疾病,对男性生育能力有重大影响。完全全球精症表现为精子头 100%呈圆形,缺乏顶体。这些特定的形态学改变似乎与精子发生过程中的最后阶段发生的缺陷有关,即精子形成,这将导致顶体反应异常和精子与卵透明带的结合缺陷。这将导致自然受精失败。本文旨在介绍一对夫妇的病例,他们被诊断为原发性男性不育,并成功接受了治疗。26 岁的男性伴侣进行了两次精液分析,结果显示完全圆形的精子头(形态异常),因此建议进行体外受精治疗。精液准备和辅助生殖技术的使用,包括将精子细胞胞浆内注射到辅助卵激活中,导致了一个健康孩子的诞生。这个病例的特殊性在于早期识别出完全异常的全球精症形态。这是罗马尼亚首例报道的病例,特定的辅助生殖技术和治疗方法成功地使一对患有男性完全全球精症的夫妇怀孕。
