Total testicular volume (TTV) measured with a metric tape and vernier calliper in 20 men whose wives were 12-20 weeks gestation, and in 48 infertile men was correlated with the height, weight, Ponderal Index (PI), sperm density, and total sperm in the ejaculate. There was a good correlation between TTV by tape and calliper (r = 0.96, P less than 0.001). There was a positive linear correlation between TTV and height but not with the other parameters. Giant head spermatozoa were more common in fertile Nigerian males than in fertile Asian or caucasian males (P less than 0.001). Giant head sperm and sperm with tail defects occurred in 6.25%, 11.1% fertile and 37.1%, 47.4% infertile men respectively. Spontaneous abortion due to blighted ova were more prevalent in wives whose husbands has greater than 8% giant head sperm (P less than 0.02).
用米尺和游标卡尺测量了20名妻子处于妊娠12 - 20周的男性以及48名不育男性的睾丸总体积（TTV），并将其与身高、体重、 ponderal指数（PI）、精子密度和射精中的总精子数进行了相关性分析。用米尺和游标卡尺测量的TTV之间存在良好的相关性（r = 0.96，P < 0.001）。TTV与身高呈正线性相关，但与其他参数无关。大头精子在尼日利亚可育男性中比在亚洲或白种人可育男性中更常见（P < 0.001）。大头精子和有尾部缺陷的精子分别在6.25%、11.1%的可育男性和37.1%、47.4%的不育男性中出现。因枯萎卵导致的自然流产在丈夫大头精子大于8%的妻子中更为普遍（P < 0.02）。
