In accordance with a World Well being Group (WHO) examine (2017), about half of all infertility is because of males. Semen evaluation is taken into account important for prognosis of male infertility, however is just not available at medical establishments apart from these specializing in infertility therapy, and there’s a excessive threshold for receiving it.
On this examine, a bunch led by Affiliate Professor Hideyuki Kobayashi of the Division of Urology, Toho College College of Drugs, Tokyo, Japan developed an AI mannequin that may predict the danger of male infertility with out the necessity for semen evaluation by solely measuring hormone ranges in a blood check. AI creation software program that requires no programming was used for the mannequin, and the examine was reported within the British scientific journal Scientific Stories. The AI prediction mannequin was primarily based on information from 3,662 sufferers and had an accuracy price of roughly 74%. Specifically, it was 100% right in predicting non-obstructive azoospermia, essentially the most extreme type of male infertility.
The present examine collected scientific information from 3,662 males who underwent semen and hormone testing for male infertility between 2011 and 2020. Semen quantity, sperm focus, and sperm motility have been measured within the semen exams, and LH, FSH, PRL, testosterone, and E2 have been measured within the hormone exams. T/E2 was additionally added. Complete motile sperm rely (semen quantity X sperm focus X sperm motility price) was calculated from the semen check outcomes. Primarily based on the reference values for semen testing within the WHO laboratory guide for the examination and processing of human semen, sixth version (2021), a complete motile sperm rely of 9.408 X 106 (1.4 mL X 16 X 106/mL X 42%) was outlined because the decrease restrict of regular, assigning a worth of “0” if the whole motility sperm rely for a person affected person was above 9.408 X 106 and a worth of “1” when it was beneath. The accuracy of the AI mannequin was roughly 74%.
Subsequent, the AI mannequin was validated utilizing information from 2021 and 2022 for which each semen and hormone exams have been out there. Utilizing the information of 188 sufferers in 2021, the accuracy was about 58%, whereas accuracy utilizing the information for 166 sufferers in 2022 was about 68%. Nonetheless, non-obstructive azoospermia may very well be predicted with a 100% accuracy price in each 2021 and 2022.
In accordance with Affiliate Professor Kobayashi, “This AI prediction mannequin is meant solely as a major screening step previous to semen testing, and whereas it’s not a substitute for semen testing, it may be simply carried out at services apart from these specializing in infertility therapy.”
The AI prediction mannequin used on this examine was significantly correct in predicting non-obstructive azoospermia, which is a extreme type of azoospermia. When the prediction mannequin detects irregular values, since sufferers might probably have non-obstructive azoospermia, this must be a set off for them to bear detailed testing at a specialist infertility clinic and obtain acceptable therapy.”

CreaTact, Inc. (Mito Metropolis, Ibaraki Prefecture, Japan; President: Iori Nakaniwa) is conducting software program improvement and information evaluation to develop a business authentic AI prediction mannequin for the above objective. “Sooner or later, we hope that scientific laboratories and well being checkup facilities will use our AI prediction mannequin to display screen for male infertility, thereby making testing for male infertility, extra accessible by overcoming hurdles to it,” stated Affiliate Professor Kobayashi.
The examine was revealed in Scientific Stories on 31 July, 2024.
