Lack of species-specificity in mammalian sperm chemotaxis
(Academic Press Inc Elsevier Science, 2003)
Dynamics of energy reserves and the cost of reproduction in female and male fiddler crabs
(Elsevier Gmbh, 2018-02)
The physiological costs of reproduction can be measured as the energy allocated to reproductive activities. In fiddler crabs, females allocate energy to vitellogenesis and brooding, whereas males perform expensive courtship ...
Methyl eugenol effects on Bactrocera dorsalis male total body protein, reproductive organs and ejaculate
(Wiley Blackwell Publishing, Inc, 2018-10)
Methyl eugenol (ME) and inclusion of protein into the adult diet increase the mating competitiveness of the Oriental fruit fly, Bactrocera dorsalis (Hendel). Exposing males to ME or protein is a promising post-teneral ...
Feeding on methoprene increases male accessory gland size and body protein in the Mexican fruit fly
(Wiley Blackwell Publishing, Inc, 2021-06)
Methoprene, a juvenile hormone analog, accelerates male sexual maturation in some pest species controlled through the Sterile Insect Technique (SIT). The SIT consists of the mass-rearing, irradiation and release of insects ...
Egg production in relation to paternal weight in a freshwater caridean shrimp (Decapoda)
(Wiley Blackwell Publishing, Inc, 2019-04)
In diverse invertebrate species, sperm quantity and quality are positively correlated with male size, egg fertilization rates being consequently affected by paternal weight. This factor may also have an indirect effect on ...
Electroejaculation in the Chinchilla (Chinchilla lanigera): Effects of anesthesia on seminal characteristics
(Elsevier, 2005-02)
Repetitive electroejaculation is probably extremely stressful in conscious animals and could adversely affect fertility. The present study was designed to (a) evaluate the effects of anesthesia (40 mg ketamine/kg body ...
Spermatogenesis, Spermatophore, and Seminal Fluid Production in the Adult Blue Crab Callinestes danae (Portunidae)
(Oxford University Press, 2012-01)
Sperm and spermatophore production in Callinectes danae Smith, 1869 were examined by histochemistry and correlated with gonadosomatic (GSI) and hepatosomatic (HSI) indices. The GSI from developing (DE) and mature (MAT) ...
Evolutionary and functional significance of lengthy copulations in a promiscuous apple snail, Pomacea canaliculata (Caenogastropoda: Ampullariidae)
(Oxford University Press, 2011-02)
The peculiar adaptations of the dioecious freshwater snails belonging to the family Ampullariidae have recently been recognized as important, albeit neglected, models for evolutionary ecology studies. A review of the ...
Impact on reproductive performance and body condition in a small limpet parasitized by a large castrator pea crab
(Wiley-liss, div John Wiley & Sons Inc., 2021-08)
Parasitic castrators utilize the energy reserves that the host allocates on reproduction resulting in sterilization of the host. However, whether other processes (e.g., growth) are also impaired depends on the balance ...
Serum AMH level can predict the risk of cycle cancellation and the chances of good ovarian response, independently of patient’s age or FSHAMH sérico pode predizer o risco de cancelamento de ciclo e as chances de boa resposta ovariana, independentemente da idade ou FSH
(Brazilian Society of Assisted Reproduction, 2013-04-13)
In the recent years, anti-Müllerian hormone (AMH) has been shown to represent a reliable marker of the ovarian reserve. In this study, we evaluate the risk of cycle cancellation and the chances of good ovarian response to ...
