Proper timing of the reproductive cycle to assure mate access is critical to optimizing success. We tested the importance of male presence on the progression of the female reproductive cycle in the blood python, Python curtus. Upon reaching sexual maturity, captive-born, individually raised virgin female snakes were housed with either a conspecific male or female. At the onset of the reproducti...

Background: Micronutrients in support to the carbon cycle were shown to reduce sperm DNA damage both in animal models and infertile men. Besides supporting DNA methylation, their positive effect may be mediated by an improved performance of the endogenous antioxidant system but this has not yet been proven in clinical settings. The present study aimed at evaluating the effects of micronutrient ...

Coleoid cephalopods are thought to go through only one reproductive cycle in their life. We here report that vampire squid (Vampyroteuthis infernalis) show evidence of multiple reproductive cycles. Female vampire squid spawn their eggs, then return to a resting reproductive state, which is followed by the development of a new batch of eggs. This reproductive cycle is likely to be repeated more ...

Morphometric changes in body condition, liver, sonic muscle and gonadal development associated with the annual reproductive cycle and behaviour of the intertidal-nesting male plainfin midshipman Porichthys notatus were investigated. Body condition of type I males rapidly increased during the pre-nesting (PN) period, peaked at the beginning of the summer nesting cycle and then gradually declined...

No published information are available on the reproductive indices of local Abadeh does reared innorthern Fars province, southern Iran. This study was conducted to determine the duration of the breedingseason, and the length and duration of the oestrous cycle. Twenty single parity 2-year-old does from Abadeh(weighing 19–26 kg) were purchased and transferred to the School of Veterinary Medicine ...

In this paper, an account of various aspects related to buffalo reproduction are given. Fundamental concepts of the reproductive physiology as well as manipulation of the reproductive function will be presented. This will include an overview of the most recent developments of the oestrous cycle and the ovulation control, new strategies of reproductive management for the improvement of genetic g...

Two species of horned lizards, Phrynosoma braconnieri and P. taurus, are endemic to México and inhabit medium and high-elevation sites in the states of Oaxaca, Guerrero, and Puebla. We compiled information on distribution and reproductive cycle for these two species from the literature and from an examination of specimens in systematic collections. Our study confirms a viviparous mode of reprod...

Previous studies showed that females in the proestrus stage of the reproductive cycle maintain organ functions after trauma-hemorrhage. However, it remains unknown whether the female reproductive cycle is an important variable in the regulation of lung injury after trauma-hemorrhage and, if so, whether the effect is mediated via upregulation of heme oxygenase (HO)-1. To examine this, female Spr...

Respected Chairpersons, Teachers and Colleagues, I thank the Indian Psychiatric Society forgiving me the opportunity and honor of delivering this year's Tilak Venkoba Rao Oration. The topic of today's oration is based on research done by my colleagues and me over the last several years. The canvas of the topic the interface of psychiatry and women's reproductive health is very wide. It encompas...

Social mammals have three basic stages of postnatal development: infant, juvenile, and adult. Some species also have a brief female post-reproductive stage. The human life cycle, however, is best described by five stages: infant, child, juvenile, adolescent, and adult. Women in both traditional and industrial societies may also have a long post-reproductive stage. Analyses of bones and teeth of...
