In nearly all animals from a laboratory breeding colony that were examined (85/86) the right ovary was significantly larger than the left. Although primordial follicles were present in both ovaries, Graafian follicles and CL were noted only in the right ovary. The left ovary usually had a much less prominent intraovarian vascular supply, and it is suggested that this may play a central role in limiting the ability of follicles to grow on that side. Many of the bats examined very soon after the introduction of stud males had well-developed CL, sometimes of 2-3 different ages, and uteri that had probably been subjected to stimulation by luteal hormones. Such observations made on females that had been housed with a stud male only for 24 h indicate that the black mastiff bat is a spontaneous ovulator with a functional luteal phase. It was common to observe an extended period after the introduction of a stud male during which spermatozoa were present in the vaginal smears from a female almost every day. Most of the ovulations that resulted in pregnancies appear to have occurred during this period. Of the 72 bats with CL, 11 possessed 2 or more CL of the same age, indicating that multiple ovulations can sometimes take place. The right ovaries of all females examined during advanced pregnancy had non-atretic, vesicular or Graafian follicles in addition to the CL of pregnancy.
在几乎所有来自实验室繁殖群体且接受检查的动物（85/86）中，右侧卵巢明显大于左侧。尽管两侧卵巢均存在原始卵泡，但只有右侧卵巢发现有格拉夫卵泡和黄体。左侧卵巢的卵巢内血管供应通常不那么显著，有人认为这可能在限制该侧卵泡生长能力方面发挥核心作用。许多在引入种雄后很快接受检查的蝙蝠有发育良好的黄体，有时有2 - 3个不同年龄的黄体，并且子宫可能受到了黄体激素的刺激。对仅与种雄共处24小时的雌性所做的此类观察表明，黑獒蝠是自发排卵且有功能性黄体期的动物。在引入种雄后的一段较长时间内，常见的情况是雌性的阴道涂片几乎每天都有精子。大多数导致怀孕的排卵似乎都发生在这段时间。在有黄体的72只蝙蝠中，11只拥有2个或更多相同年龄的黄体，这表明有时会发生多次排卵。在妊娠后期接受检查的所有雌性的右侧卵巢，除了妊娠黄体外，还有未闭锁的囊状或格拉夫卵泡。
