In this study, we identified two novel heterozygous variants in the LHCGR gene (c.349G>A, p.Gly117Arg and c.878C>A, p.Ser293 (*)) causing type 1 Leydig cell hypoplasia in a 2.75 year old patient presenting with female external genitalia and bilateral testis tissue in the inguinal region.

Immunohistochemical analysis revealed that the StAR was exclusively localized in Leydig cell of the interstitial compartment, even though non-specific immunostaining of STAR was often found within the seminiferous tubules, especially acrosomal regions of spermatozoa (Figure 3C, Table 3).

Other ovarian tumors include steroid cell tumor, ovarian luteoma, and Leydig cell tumor.
There is still debate concerning the carcinogenesis of primary testicular carcinoid tumors since the presence of NE cells in the testis has not been yet described with hypotheses postulating the origin to be the same precursor cell as Leydig cells, while others attributing it to a chromosomal abnormality [7, 13].
In adult rat Leydig cell cultures, both retinol and retinoic acid-enriched media showed a direct stimulatory effect on testosterone biosynthesis via 3[beta]-HSD compared to control media, as measured by radioimmunoassay.
Theophylline, a caffeine metabolite and pharmaceutical used in the treatment of asthma had previously been shown to impair Leydig cell development in the rat (Pollard et al.
