Medical Corporation Shokokai 'Tennoji Ekimae Gynecology Nare Clinic' (Tennoji-ku, Osaka / Director: Takashi Henmi) will introduce the 'LOX Test', a new test for fertility treatment that evaluates 'natural pregnancy potential (fertility)' on a 7-point scale by measuring the percentage of senescent cells (LOX cells) in the blood.
It supports rational treatment choices without regrets: whether to proceed with artificial insemination (IUI) or in vitro fertilization (IVF).

## Background
Many patients feel that fertility treatment is a race against time.
Especially when undergoing fertility treatment past the optimal reproductive age, the accumulation of choices to 'just try it out' directly leads to the consumption of time, making it easy to feel physical and mental stress.
Repeating artificial insemination multiple times without results means that by the time they move on to the next step, they have aged further.
During that time, there is anxiety that the quality of eggs is gradually declining. We often hear consultations that repeating the cycle of hope and disappointment surely exhausts the mind, not just the financial cost.
At our clinic, with the desire to reduce such 'detour fertility treatments', we focused on the 'natural pregnancy potential (fertility)' which could not be seen with previous tests, and decided to introduce the LOX test developed by TL Genomics Co., Ltd.

## What the LOX Test Reveals
The higher the LOX value, the more it is a sign that aging is progressing. And according to research, **it has become clear that women with high LOX values tend to have difficulty conceiving naturally.** The relationship between the ease or difficulty of natural conception and aging has been reported in a joint study by the National Cerebral and Cardiovascular Center and Osaka Metropolitan University.
With this test, **you can examine how much physical aging has progressed** and **whether you are in a condition where natural conception is likely (natural pregnancy potential).** The results are communicated in terms like 'equivalent to early 20s' or 'equivalent to 30s'.
*Even if the LOX value is high, it is not related to the success rate of in vitro fertilization (IVF).
