        Prenatal exposure to androgen excess increases LH pulse amplitude during postnatal life in male sheep 

        Recabarren, S. E.; Recabarren, M.; Rojas García, Pedro; Cordero, M.; Reyes, C.; Sir Petermann, Teresa (2012)
        Prenatal exposure to excess testosterone has a profound impact on reproductive and metabolic functions in young and adult female sheep. Nevertheless, few studies have addressed the impact of prenatal exposure to an excess ...

        Congenital adrenal hyperplasia causing male infertility. Report of one case Alteración de la fertilidad masculine por hiperplasia suprarrenal congénita. Azoospermia reversible con terapia de glucocorticoide 

        Enzo Devoto, C.; Marcia Madariaga, A.; Fernández, Wanda (2011)
        In males, congenital adrenal hyperplasia due to 21 hydroxylase defi ciency is associated to normal fertility or infertility caused by a hypogonadotrophic hypogo-nadism (HH) or gonadal damage caused by intratesticular adrenal ...

        Do female Nicrophorus vespilloides reduce direct costs by choosing males that mate less frequently? 

        Hopwood, P. E.; Mazué, G. P. F.; Carter, M. J.; Head, M. L.; Moore, A. J.; Royle, N. J. (Royal Soc, 2016)
        Sexual conflict occurs when selection to maximize fitness in one sex does so at the expense of the other sex. In the burying beetle Nicrophorus vespilloides, repeated mating provides assurance of paternity at a direct cost ...

        Interactions between males of the lizard Liolaemus tenuis: Roles of familiarity and memory 

        Trigosso-Venario, Rodrigo; Labra, Antonieta; Niemeyer, Hermann M. (2002)
        For territorial organisms, recognition of familiar individuals can reduce the frequency and intensity of aggressive encounters ('dear enemy' phenomenon), stabilize social systems, and reduce the cost of territory maintenance. ...

        Male wing fanning by the aphid parasitoid Aphidius ervi (Hymenoptera: Braconidae) produces a courtship song. 

        Villagra, C. A.; Pinto, C. F.; Penna, M.; Niemeyer, H. M. (2011)
        We, herein, report evidence that wing fanning by the aphid parasitoid Aphidius ervi Haliday (Hymenoptera: Braconidae) constitutes a courtship song. Complete removal of the forewings or only the distal half of them reduced ...

        Breeding and parental behaviour in the glass frog Centrolene savagei (Anura: Centrolenidae) 

        Vargas-Salinas, Fernando; Quintero-Ángel, Andrés; Osorio-Domínguez, Daniel; Rojas-Morales, Julián Andrés; Escobar-Lasso, Sergio; Gutiérrez-Cárdenas, Paul David Alfonso; Rivera-Correa, Mauricio; Amézquita, Adolfo (Taylor and Francis Ltd., 2014)
        We examine factors that influence male mating success in the glass frog Centrolene savagei; in addition, we describe courtship behaviour, oviposition and early parental behaviour. Fieldwork was conducted in the Colombian ...

        Sexual differences in the toxicity of procaine in rats 

        Munoz, Carlos; Guerrero, Sergio; Paeile, Carlos; Campos, Iris (1961)
        The toxicity of procaine has been found to be markedly different in the male and female albino rat. The convulsant dose-50 of procaine, injected intraperitoneally (i.p.), was significantly higher in the male rat. It decreased ...

        Prenatal testosterone treatment alters LH and testosterone responsiveness to GnRH agonist in male sheep 

        Recabarren, Sergio E.; Lobos, Alejandro; Figueroa, Yara; Padmanabhan, Vasantha; Foster, Douglas L.; Sir Petermann, Teresa (Society of Biology of Chile, 2007)
        Although evidence is accumulating that prenatal testosterone (T) compromises reproductive function in the female, the effects of excess T in utero on the postnatal development of male reproductive function has not been ...

        Molecular mechanism of action of the male sex hormones 

        Minguell, José J.; Sierralta, Fernando (1975)
