It has been previously demonstrated that 7,12-dimethylbenz(a) anthracene (DMBA) is an initiator of ovarian granulosa cell tumors. It is also known that DMBA leads to destruction of primordial oocytes, and that tumor induction may involve the interaction of pituitary gonadotropins. However, the effects of DMBA on ovarian steroidogenesis and uterine growth in relation to the tumorigenic process have not been investigated. Therefore, the present study was conducted to examine these parameters using adult C57Bl/6N mice treated in proestrus and diestrus II with 0.1 ml corn oil with or without 1.5 mg DMBA and killed 44 hours later. The uteri and …

Fifty-six semen samples from males under examination for suspected subfertility were examined to determine if alterations in specific semen parameters could be associated with the presence or absence or Ureaplasma urealvticum. Twenty-seven (48.2%) of the specimens cultured positive for U· urealyticum in U9B urease broth and A-7 differential agar. Both positive and negative specimens have a normal average motility rating. Overall sperm counts (millions per ml) were slightly lower and ejaculate volumes higher in U. urealvticum positive samples. Morphological abnormalicies were not found more frequently in U. urealyticum positive samples. No statistically significant difference between seminal parameters of U. …
