The influence of sex hormones on the differentiation of gonads and gonaducts in the fowl has been the concern of a large number of investigators. They studied the effects of various kinds of sex hormones on the sexual differentiation of chick embryos and young birds and discussed the mechanism of development of reproductive organs in relation to the action of sexual hormones.

The influence of sex hormones on the differentiation of gonads and gonaducts in the fowl has been the concern of a large number of investigators. They studied the effects of various kinds of sex hormones on the sexual differentiation of chick embryos and young birds and discussed the mechanism of development of reproductive organs in relation to the action of sexual hormones. But most of the authors either did not use the embryos and the chicks of genotypically known sex as experimental materials or only investigated the action of sex hormones on the development of the reproductive systems anatomically. The present authors made use of the autosexing embryos and chicks as experimental materials, and investigated the action of sex hormones on the differentiation of gonads and gonaducts anatomically as well as histologically in order to elucidate the mechanism of sexual differentiation on a more sound basis.All the eggs used in this study were obtained from the crosses between barred hens and non-barred cocks, giving only barred males and non-barred females. The hormonal treatments were given by two different methods, one was injection of hormones into the un-incubated or incubating eggs, and the other was immersion of un-incubated eggs in hormone solutions. In the former, the female sex hormones diethylstilbestrol, estradiol, hexesterol and ovarian tissue extract and the male sex hormone testosterone were employed, while in the latter, however, only the female sex hormone diethylstilbestrol was used. The main results of the hormone treatments thus obtained are presented schematically in the accompanying table.Since in the initial stage of sexual differentiation, the gonads are amphisexual, the left gonad of birds possesses two components, an outer ovarian cortex and an inner portion, the medulla; the right gonad primordium, on the other hand, consists of only the medullary portion, generally lacking the incipient ovarian epithelium. The female hormones tend to activate the female component in embryos of either sex and suppress the male components. The male hormone has just the opposite effect, it stimulates the male component and suppresses the female component. After the treatment of female sex hormone, the gonads of genetic male birds tend to be flattened, with cortex thickened to form a kind of ovatestes. After the treatment of male hormone, on the contrary, the left gonad of the genetic female tends to be elongated, and to form a structure similar ??to that of the male sex cords, but the right gonad is not affected to any visible degree. In most of the cases, the latter remains to be small or degenerated completely.The degree of sex reversal depends to a large extent on the quantity of hormones given, the heavier the dosage used, the more complete with the sex reversal. But in no case complete sex reversal has been observed even though the dosage employed was as high as 2 mg. This suggests that the direction of sex differentiation is primarily controlled by the quantitative balance between the opposing sets of male and female determining genes. The moditications in the course of sexual differentiation as affected by the treatment of sex hormones are probably secondary in nature.In the development of male birds, the Müllerian ducts disappear entirely and the Wolffian ducts persist as the vasa differentia. In the case of females, the left Müllerian duct persists as the functional oviduct, the right one degenerating and the Wolffian ducts only persist in a rudimentary state. After hormone treatment, the Müllerian ducts persist, though somewhat hypertrophied, regardless whether the treated animals are genotypic males or females. This may be explained as either due to that the administrated hormones disturb the normal differentiation courses of the Müllerian ducts directly or due to that administrated hormones interfere with the normal differentiation of the gonads, and then cause the abnormal retention of the Müllerian ducts.

1. 试验用的鸡胚和雏鸡都是"芦花鸡♀×浦东鸡♂"的第一代杂种,遗传型雄性都是芦花斑纹,遗传型雌性都不是芦花斑纹.试验分二组,第一组是把雌性激素已雌酚、雌二醇、催情素、卵巢组织液及雄性激素丙酮睾丸素在入孵前或入孵后3~4天注入鸡蛋内,第二组是把鸡蛋在入孵前浸泡在己雌酚油剂、乳剂或其它溶液中.2. 蛋内注入或浸泡雌激素后,遗传型雄性鸡胚的性腺趋向扁平、皮质部增厚,形成卵睾.把丙酮睾丸素注入蛋内,少数遗传型雌性鸡胚的卵巢成长圆形、有形成精索的迹象.但都不能引起完全的性别转化.3. 用性激素处理鸡胚,不论是遗传型雌性的还是遗传型雄性的,都可诱导双输卵管的存留,不过在外观上左侧输卵管比较正常些,右侧多成盲囊等不规则形态,管内充满液体或淡黄色物质.4. 性腺有二个部分,外侧是胚质上皮,内层是雄性髓部.鸡胚性腺的分化最初是由雌性基因与雄性基因的量的平衡决定的,当性腺分化到一定程度后,性腺本身所分泌的性激素也起着很重要的作用.注射或浸泡后进入鸡胚的相反性激素只可使性腺分化发生局部改变,因为(1)进入的性激素是单一种类的,而鸡胚或雏鸡所分泌的性激素是有一定比例而且相互制约的,(2)性分化的方向最终还是受雌雄性基因的量的平衡决...

Methods Laparoscopy was carried out for 4 cases of true hermaphroditism for exploration,gonadal biopsies,gonadectomies and resection of internal ductal structure contradictory to sexual assignment. Results Gonads and internal genital organs were successfully found in these 4 cases. After confirmation of true hermaphroditism through exploration and gonadal biopsy, 3 cases were assigned as male gender, ovarian tissue and mullerin duct remants were then removed, and male urethras was reconstructed.Cryptorchidopexy was done for 2 of them. 1 cases was assigned as female gender.So testicular tissue and wolffian duct remants were removed, and vagina was reconstructed.No obvious post operative complication has been observed. Malignant change of the remant gonad has not been observed after 6 to 54 monthes of follow up. Conclusions Laparoscopy as a minimally invasive procedure can take the place of open surgical procedure in the diagnosis and treatment of true hermaphroditism.
