gonad

1 In both male and female embryos, the same group of cells has the potential to develop into either the male or female gonads; this tissue is considered bipotential.

2 Objective: To explore CT image of yolk sac tumor out of gonad.

目的：探讨CT在性腺外卵黄囊瘤的临床应用价值。

3 Those eyes are enlarged for a reason, as the gonad will often need to navigate in murky waters.

4 Identify the changes in sensitivity that occur in the hypothalamus, pituitary, and gonads as a boy or girl approaches puberty.

5 Sure, some people might find urchin gonads an acquired taste.

6 An increase in gonad hormone production then inhibits gonadotropin-releasing hormone production.

7 Mammalian primordial germ cells form and migrate to the gonad during embryonic development.

在胚胎发育时期,原始生殖细胞形成并迁移至生殖腺,形成种系囊.

8 Eventually, the treated fish developed gonads and reached sexual maturity, producing offspring that inherited their parents' genetic sterility.

9 The effect of cadmium on the female gonad was shown to have the extrous cycle delayed and the proportion of atresic follicle increased.

镉的雌性性腺生殖毒性可表现为动情周期的明显延长，卵巢细胞生长发育过程的明显障碍。

10 As an infant, her gonads were removed, which she considers a castration.

11 I understood that both these things grew out of the same fetal gonad, but that didn’t matter.

12 Sublethal levels of the chemical halt cell division in the gonads.

13 The scientists won't have the full results until this fall, after the first generation is 8 to 10 months old — the age at which salmon normally develop gonads.

14 If SRY is missing, the gonad develops into an ovary, even if the embryo is male.

如果SRY基因缺失，即使胚胎是男性的，其性腺也会发育成卵巢。

15 Cholesterol is mainly synthesized in the liver and is the precursor to many steroid hormones such as testosterone and estradiol, which are secreted by the gonads and endocrine glands.

16 "Look," Banner said to me this morning, pointing up at the twin black exhaust vents either side of the Jaguar's tail, "there's his gonads."

17 Serial hermaphroditism, where the gonad can switch from producing sperm to ova, may also be seen in some species.

18 The worm has organs called gonad primordia on the underside of its posterior end.

19 The hunch here was that a person’s gonads would orchestrate sexual development, especially at puberty.

20 The tests also found that adult male fish exposed to bifenthrin an cyhalothrin as larvae had smaller gonads than the control group, while the second generation had increased fecundity.
