Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On November 26, 2025, the Company filed a Certificate of Change (the “Certificate of Change”) with the Secretary of State of the State of Nevada to effectuate a 1-for-8 reverse stock split (the “Reverse Stock Split”) of the Company’s issued and outstanding and authorized shares of Common Stock. The Reverse Stock Split became effective at 12:01 a.m., Eastern Time, on Friday, November 28, 2025, and the Company’s Common Stock began trading on a split-adjusted basis when The Nasdaq Stock Market (“Nasdaq”) opened on November 28, 2025.

When the Reverse Stock Split became effective, every 8 shares of Common Stock issued and outstanding were automatically reclassified and combined into one share of Common Stock, without any change in the par value per share, and a proportionate adjustment was made to the Company’s authorized shares of Common Stock such that the Company now has 6,250,000 shares of authorized Common Stock. In addition, a proportionate adjustment has been made to the per share exercise price and the number of shares issuable upon the exercise of all outstanding stock options and warrants to purchase shares of Common Stock and the number of shares reserved for issuance pursuant to the Company’s equity incentive compensation plans. No fractional shares of Common Stock were issued in connection with the Reverse Stock Split. Stockholders who otherwise would have been entitled to receive fractional shares of Common Stock had their holdings rounded up to the next whole share.

The Company’s Common Stock will continue to trade on The Nasdaq Capital Market under the existing symbol “IVF”, but the security has been assigned a new CUSIP number (44984F807).

The foregoing description of the Certificate of Change does not purport to be complete and is qualified in its entirety by reference to the full text of the Certificate of Change which is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 8.01 Other Events

On November 25, 2025, the Company issued a press release announcing the Reverse Stock Split. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
