It is a centrally acting analgesic used to treat moderate to severe pain. During preclinical investigations into the safety of drugs and chemicals, many are found to interfere with the reproductive function of the female rat (Yuan and Foley 2002).This interference is commonly expressed as a change in normal morphology of the reproductive tract or a disturbance in the duration of particular phases of the estrous cycle. Male Reproduction Veterian Key. » Product Support At fertilization, the chromosomes in one male gamete, called a sperm (or spermatozoon), combine with the chromosomes in one female gamete, called an oocyte. G L Rodríguez-González 1, C C Vega 1, L Boeck 1, NORMAL FEMALE REPRODUCTIVE TRACT HISTOLOGY Ovary 1.1 The paired ovaries of the rat are grape-like structures that vary in gross appearance and size, depending on the stage of the oestrous cycle.
