Background: Reproductive activity is an important biological process that always take place between married and unmarried couples across the globe. The study was carried out to evaluate effect of COVID-19 on reproductive during post-lockdown in Rivers state. aim state.Methods: A well-structured questionnaire containing demographics were administered participants. Each participant had one fill a...

The seasonality of reproductive activity in the ewe in temperate latitudes is controlled by photoperiod. Its annual variations control the temporal organization of the sexual cycle by changing the activity of the gonadotrophic axis. Cyclic oestrous behaviour usually appears in the ewe at the end of summer or the beginning of autumn and finishes in winter or at the very beginning of spring. Seas...

Opioid peptides have been localized in a variety of peripheral tissues like placenta, thyroid, pancreas, gastrointestinal tract, in the reproductive tract of male and female and in the testes of rats. Immunoassayable material was detected in extracts of gonads, reproductive tract and accessory reproductive organs. Studies with naloxone have suggested that beta-endorphin may have an important ro...

Climate change, human disturbance, and disease can have large impacts on the dynamics of a species by affecting the likelihood of survival and reproduction of individuals. We investigated the roles of precipitation, off-road vehicle (ORV) alteration of habitat, and infection with Sin Nombre virus on the survival and reproductive probabilities of deer mice (Peromyscus maniculatus). We used gener...

OBJECTIVE The primary objectives of the present study were to (1) contrast reproductive hormone levels and ratings of menstrual distress of female migraineurs with those of a control group in each menstrual cycle phase, (2) examine correlations between hormone levels and migraine frequency, severity, and migraine-related disability, and (3) examine correlations between menstrual distress and mi...

Differences in individual locomotor activity patterns may be linked to a number of ecological factors, such as changes ambient temperature or photoperiod. Observations on subterranean mammals suggest that they exhibit diel rhythms despite the lack visual cues their underground burrows, but it is unknown how seasonality and characteristics affect activity. In this study we use RFID technology mo...
