The extravagance and diversity of external genitalia have been well characterized in male primates; however, much less is known about sex differences or variation in female form. Our study represents a departure from traditional investigations of primate reproductive anatomy because we 1) focus on external rather than internal genitalia, 2) measure both male and female structures, and 3) examine a strepsirrhine rather than an anthropoid primate. The subjects for morphological study were 21… 
Clitoral length in immature and mature captive tufted capuchin (Sapajus spp.) females: A cross‐sectional study
TLDR
The results suggest that the small body size may be only in part responsible of the perception of long clitoris in female infants, since the clitoris is actually longer in immature females compared to adult ones and its size is inversely related to body weight.
Variation in Penile and Clitoral Morphology in Four Species of Moles
TLDR
This dissertation is focused on four species of moles, all of which defy the conventionally obvious visual distinctions between males and females, and the potential role of hormones in development of the external genitalia in these species is investigated.
Anatomy of mole external genitalia: Setting the record straight
TLDR
Histological examination demonstrates that perineal appendages of male and female broad‐footed moles are the prepuce, which in both sexes are covered externally with a hair‐bearing epidermis and lacks erectile bodies.
Macroscopic digestive anatomy of ring-tailed lemurs (Lemur catta), including a comparison of frozen and formalin-stored specimens
TLDR
The proportions of length measurements did not change markedly during ontogeny, indicating that proportions developed in the foetus are already representative for the adult animal, and width and tissue-mass scaling of the caecum indicated a disproportionate growth of this organ duringOntogeny that was not reflected in its length.

Intraspecific macroscopic digestive anatomy of ring-tailed lemurs (Lemur catta), including a comparison of frozen and formalin-stored specimens
TLDR
The proportions of length measurements did not change markedly during ontogeny, indicating that the proportions of the foetus are representative of those of the adult animal, and width and tissue-mass scaling of the caecum indicated disproportionate growth of this organ during ontageny that was not reflected in its length.
Comparative Morphology of the Penis and Clitoris in Four Species of Moles (Talpidae)
TLDR
P phylogenetic affinity and the presence/absence of ovotestes are poor predictors for most sex differentiation features within mole external genitalia.
Female rule in lemurs is ancestral and hormonally mediated
TLDR
It is suggested that relaxation of hormonally mediated FSD emerged only recently and that female masculinization may be the ancestral lemur condition, an idea that could revolutionize the understanding of the ancient socioecology and evolution of primate social systems.

It seems that either penile spines have several functions, or penile spinosity in primates, and other orders, remains to be explained.

TLDR
Research on the "masculinized" genitalia of moles and hyenas is described, raising intriguing possibilities regarding the coordinated role that androgens, estrogens and peptide hormones (e.g., relaxin) might play, at different stages of sexual differentiation and development, in preparing genital tissues for their functional roles in reproduction.

TLDR
It is suggested that postnatal phallic growth is largely independent of gonadal steroids, with oestrogenic facilitation of female-typical clitoral characteristics in spotted hyaenas.

TLDR
It is evident that the unusual sexual behaviors of the male and female spotted hyenas are facilitated by unique structural modifications of the relevant organs.

TLDR
Pregnant spotted hyaenas were treated with anti-androgens to interfere with the unusually masculine 'phallic' development that characterizes females of this species, and the present data suggest that development of the male penis and scrotum and the female clitoris and pseudoscrotum, in spotted hyAenas may involve both androgen-dependent and androgen -independent components.

TLDR
Gonadectomy (two males and four females) at 4-7 months resulted in nondetectable concentrations of testosterone and oestrogen and a marked attenuation in androstenedione, indicating that the gonads are the major source of these three steroids.
