This study evaluated the potential of slow-release GnRH agonist (deslorelin) implants to inhibit reproductive function in the male tammar wallaby. The specific aim was to measure the effects of graded dosages of deslorelin on testes size and plasma L

Non-lethal management techniques are needed for overabundant captive and wild populations of macropodid marsupials for which lethal techniques are considered inappropriate and may be hazardous. The tammar wallaby, Macropus eugenii, was used as a mode

Estrogens have a feminizing effect on gonadal differentiation in fish, amphibians, reptiles, and birds. However, the role of estrogen during gonadal differentiation in mammals is less clear. We investigated the effect of estrogen on gonadal different

The formation of the testis or ovary is a critical step in development. Alterations in gonadal development during fetal or postnatal life can lead to intersexuality or infertility. Several model systems have been particularly useful in studying gonad

Marsupials have two anatomically separate uteri; and in macropodids (kangaroos and wallabies), there is a single ovulation from alternate ovaries in each cycle. During late pregnancy, the two uteri are differentially regulated by local hormonal influ

Expression of Sox3 has been detected in the testes of humans and of developing and adult mice at the same time as Sox9 and Sry. The co-expression of these three related Sox genes in the mouse indifferent gonadal ridge led to the hypothesis that these

Mouse blastocysts appear to be under direct inhibition from the uterine environment, whereas no evidence of direct inhibition during diapause in the tammar wallaby has been observed. Normally developing (day 4) and quiescent mouse blastocysts were in

Glucocorticoid hormones may play a critical role in initiating parturition in tammar wallabies. In this study, we investigated the concentration of cortisol in fetal fluids and cortisol production by fetal adrenals over the last 3 days of the 26-day

In the marsupial tammar wallaby, virilization begins approximately 3 wk after the onset of testosterone synthesis. In the eutherian mammal, in contrast, the onset of virilization of the male urogenital tract occurs shortly after the onset of androgen

Metabolic reactivation of the tammar blastocyst appears to be characterized by a change in the pathway of glucose metabolism rather than an absolute increase in substrate uptake. The switch in type of metabolism used was examined to gain information
