To determine if spermatozoa are present in the preejaculatory penile secretion, originating from Cowper's gland.
Prospective clinical and laboratory study.
Andrology and Sex Counseling Unit, Department of Obstetrics and Gynecology, Academic Teaching Hospital.
Five patients referred for premature ejaculation, three for excessive fluid secreted during foreplay and four normal healthy volunteers.
Glass slide smears of preejaculatory Cowper's gland secretion obtained during foreplay from at least two different occasions, and semen samples after masturbation.
Microscopic examination of air-dried smears, and routine semen analyses.
None of the preejaculatory samples contained sperm. All the patients had sperm in routine sperm analyses.
Preejaculatory fluid secreted at the tip of the urethra from Cowper's gland during sexual stimulation did not contain sperm and therefore cannot be responsible for pregnancies during coitus interruptus.
确定源于考珀氏腺的射精前阴茎分泌物中是否存在精子。
前瞻性临床及实验室研究。
学术教学医院妇产科男科与性咨询科。
五名因早泄转诊的患者、三名因前戏时分泌过多液体转诊的患者以及四名正常健康志愿者。
在至少两个不同场合的前戏过程中获取射精前考珀氏腺分泌物的玻片涂片，以及手淫后的精液样本。
对风干涂片进行显微镜检查以及常规精液分析。
射精前样本中均未发现精子。所有患者的常规精子分析中均有精子。
性刺激期间考珀氏腺分泌至尿道末端的射精前液中不含精子，因此在中断性交时不会导致怀孕。
