A widespread and distinctive form of amphipod intersexuality not induced by known feminising parasites.
Intersexuality occurs in a diverse range of animals, and its study offers insights into basic reproductive biology. Investigations in amphipods suggest intersexuality results from incomplete feminisation caused by sex-distorting parasites. It has also been noted that 2 intersex phenotypes occur in males of the amphipod Echinogammarus marinus, an external phenotype, in which males possess rudime...

متن کاملSexual differentiation of gonads as a function of temperature in the turtle Emys orbicularis: endocrine function, intersexuality and growth.
Emys orbicularis is a freshwater turtle with temperature-dependent sex determination. Estrogens play a major role in gonadal differentiation; when they are produced at high levels during the thermosensitive period (TSP), ovaries differentiate; when their synthesis is very low, testes differentiate. Estrogens are synthesized from androgens through the activity of aromatase. We examine here two a...
متن کاملInvestigation of the Protective Effects of Amlodipine on the Structure and Function of Testicular Tissue following Experimental Unilateral Cryptorchidism in Rats
Objective- Cryptorchidism, common birth defect of the male genital tract, is one of the causes of fertility problems. The elevation of tissue temperature following of cryptorchidism could induce oxidative stress which influences the cellular and tissue degeneration. Amlodipine is a third-generation of calcium channel blockers which has antioxidant activity. The aim of this stud...
متن کاملA Sexual Shift Induced by Silencing of a Single Insulin-Like Gene in Crayfish: Ovarian Upregulation and Testicular Degeneration
In sequential hermaphrodites, intersexuality occurs naturally, usually as a transition state during sexual re-differentiation processes. In crustaceans, male sexual differentiation is controlled by the male-specific androgenic gland (AG). An AG-specific insulin-like gene, previously identified in the red-claw crayfish Cherax quadricarinatus (designated Cq-IAG), was found in this study to be the...
