Boys and Girls with Ambitious

Our lab is interested in reproductive biology. Many things remain unknown in this field. For example, the number of oocytes ovulated at one time in mammals is determined by species (one in humans and about 10 in mice). How is this determined? Biologists have been seriously challenging with this question for a long time. However, the answer has yet to be found. Even the mechanism of ovulation, which seems much simpler than this question, has yet to be clearly explained in mammals (our laboratory's research has elucidated the molecular mechanism of medaka ovulation, but not in mammals, which are still the subject of much more research).

In recent years, the field of reproductive medicine (e.g., infertility treatment, older childbearing) has become more important due to the declining birthrate and later marriages, and reproductive biology has also contributed greatly to the development of these fields. Uncovering and understanding the underlying mechanisms of living organisms is an important step toward the applications that will follow. In other words, reproductive biology is an important discipline that provides the basic information for applied research.

A long time ago, endocrine disrupting hormones (environmental hormones) became a social concern. Although less of a concern today, the issue still remains a major concern in the field of reproductive biology. It has been pointed out that environmental hormones have adverse effects on the reproductive organs of organisms and, in extreme cases, can be critical to the survival of the species. However, when it comes to the question of how these substances disrupt reproductive functions, it is difficult to answer correctly. The main reason for this is that many of the fundamental issues in reproductive biology remain unanswered.

We are always thinking about what we can do now for the future, 100 or 200 years from now, as we conduct our daily experiments. 

We are welcome curious young researchers who are willing to conduct research with us.

If you are interested, come join us and set off on an adventure into the unknown!
