由於收集夢遺所射出來的精液有一定難度，所以只有相對較少的研究探討它的成分<ref name="Meng">{{Cite journal |last=Meng |first=Xianghu |last2=Fan |first2=Longchang |last3=Liu |first3=Jihong |last4=Wang |first4=Tao |last5=Yang |first5=Jun |last6=Wang |first6=Junkai |last7=Wang |first7=Shaogang |last8=Ye |first8=Zhangqun |date=2013-11 |title=Fresh semen quality in ejaculates produced by nocturnal emission in men with idiopathic anejaculation|language=en  |url=https://pubmed.ncbi.nlm.nih.gov/23987518 |journal=Fertility and Sterility |volume=100 |issue=5 |doi=10.1016/j.fertnstert.2013.07.1979 |issn=1556-5653 |pmid=23987518 |access-date=2022-11-02 |archive-date=2022-11-02 |archive-url=https://web.archive.org/web/20221102161914/https://pubmed.ncbi.nlm.nih.gov/23987518/ |dead-url=no }}</ref><ref name="Yedidya">{{Cite journal |last=Hovav |first=Y. |last2=Dan-Goor |first2=M. |last3=Yaffe |first3=H. |last4=Almagor |first4=M. |date=1999-08 |title=Nocturnal sperm emission in men with psychogenic anejaculation |url=https://pubmed.ncbi.nlm.nih.gov/10439013/ |journal=Fertility and Sterility |volume=72 |issue=2 |doi=10.1016/s0015-0282(99)00239-3 |issn=0015-0282 |pmid=10439013 |access-date=2022-11-02 |language=en |archive-date=2022-11-02 |archive-url=https://web.archive.org/web/20221102161913/https://pubmed.ncbi.nlm.nih.gov/10439013/ |dead-url=no }}</ref>。在最大規模的研究，其中的樣本包括從10名患有特發性不射精症的男性身上採集的遺精。精液濃度相當於來自相同男性以陰莖震動刺激所獲得的樣品，雖然精子在遺精樣本中的蠕動百分比和正常形態較高<ref name="Meng" />。
