生殖细胞在X射线照射后的敏感性和恢复能力是通过它们产生正常胚胎的能力来衡量的。精子的敏感性是卵子的3-4倍，从相同剂量的辐射中恢复所需的时间是卵子的两倍多。配子发生的早期阶段最为敏感。X射线抑制精原细胞向精母细胞的发育。在1980 r的剂量下，这种抑制持续约23天，在此期间睾丸的大小减小。在相同剂量下，卵巢大小在前7-8天内出现减少，之后恢复正常，到第22天恢复正常大小;这显然与卵母细胞形成的短暂阻滞相关。
THE sensitivity and recovery of germ cells after X-radiation were measured by their ability to produce normal embryos. The spermatozoa are 3-4 times as sensitive as the ova and require more than twice as long to recover from the same dose of radiation. The early stages of gametogenesis were most sensitive. X-rays inhibited the development of spermatogonia into spermatocytes. With a dose of 1980rthis inhibition lasted for about 23 days, during which period the testes were reduced in size. With the same dose, a reduction in ovarian size occurred during the first 7-8 days, after which normality was restored and normal size regained by the 22nd day; this was apparently correlated with a transitory block in oocyte formation.
