Evaluation of mid- and long-term impact of COVID-19 on male fertility through evaluating semen parameters

BackgroundThe coronavirus disease 2019 (COVID-19) has spread worldwide with alarming levels of spread and severity. The distribution of angiotensin converting enzyme 2 (ACE2) and transmembrane protease serine 2 (TMPRSS2) from bioinformatics evidence, the autopsy report for COVID-19 and the published study on sperm quality indicated COVID-19 could have a negative impact on male fertility. However, whether the negative impact of COVID-19 on male fertility is persistent remains unknown, which requires long-term follow-up investigation.MethodsSemen samples were collected from 36 male COVID-19 patients with a median recovery time of 177.5 days and 45 control subjects. Then, analysis of sperm quality and alterations of total sperm number with recovery time were performed.ResultsThere was no significant difference in semen parameters between male recovered patients and control subjects. And the comparisons of semen parameters between first follow-up and second follow-up revealed no significant difference. In addition, we explored the alterations of sperm count with recovery time. It showed that the group with recovery time of ≥120 and <150 days had a significantly lower total sperm number than controls while the other two groups with recovery time of ≥150 days displayed no significance with controls, and total sperm number showed a significant decline after a recovery time of 90 days and an improving trend after a recovery time of about 150 days.ConclusionsThe sperm quality of COVID-19 recovered patients improved after a recovery time of nearly half a year, while the total sperm number showed an improvement after a recovery time of about 150 days. COVID-19 patients should pay close attention to the quality of semen, and might be considered to be given medical interventions if necessary within about two months after recovery, in order to improve the fertility of male patients as soon as possible.

成都379例新型冠状病毒肺炎的临床分析

目的分析新型冠状病毒肺炎(COVID-19)患者的临床特征及预后。方法纳入成都市公共卫生临床医疗中心2020年1月16日至11月30日收治的379例COVID-19确诊病例,按照年龄分为老年组(42例,年龄≥60岁)和非老年组(337例,年龄<60岁),比较两组患者的流行病学、临床特征、实验室检查、治疗及预后。结果379例患者年龄2个月至87岁,平均41.2岁,其中男286例(75.5%),女93例。老年组平均年龄为69.5岁,女性更多见(占61.9%),大多为武汉输入和本土续发(占73.8%),以普通型和危重型为主(88.1%)。非老年组的平均年龄为37.8岁,男性更多见(80.1%),主要来自境外输入(75.7%),以轻型和普通型为主(95.0%)。179例患者(47.2%)合并一种或多种基础疾病,老年组以高血压病(15例,35.7%)及糖尿病(11例,26.2%)多见,而非老年组则以非酒精性脂肪性肝炎(132例,39.2%)多见。最常见的临床表现是发热(138例,36.4%)和咳嗽(129例,34.0%),但老年组的发热、咳嗽、呼吸困难及乏力等症状较非老年组更多见(P<0.05)。与非老年组相比,老年组的总淋巴细胞计数、CD4⁺及CD8⁺T淋巴细胞计数更低,而心肌损伤标志物及炎症指标更高(P<0.05)。139例患者(36.7%)的心脏彩色超声心动图异常,主要为左室舒张功能降低(22.7%)及心脏瓣膜反流(14.0%),且老年组患者的心脏彩色超声心动图异常率明显高于非老年组(85.7%vs.30.6%,P<0.05)。经治疗后,除老年组死亡3例外,其余均已治愈出院;但老年组的住院时间较非老年组更长(22.1 d vs.18.8 d,P=0.033)。结论成都老年COVID19患者主要来自武汉输入和本地续发,以普通型和危重型为主,常合并高血压或糖尿病等基础疾病;成都非老年COVID-19患者主要来自境外输入,以轻型和普通型为主,常合并非酒精性脂肪性肝炎;经治疗后,患者大多预后良好。
