Organization, Nature of Business, and Liquidity [Abstract]
Organization and Nature of Business	Organization and Nature of Business Femasys Inc. (the Company or Femasys) was incorporated in Delaware on February 19, 2004 and is headquartered in Suwanee, Georgia. The Company is a leading biomedical company focused on addressing significant unmet needs for women worldwide with a broad portfolio of in-office, accessible, and innovative therapeutic and diagnostic products, including a lead revolutionary product candidate and FDA-cleared products. The Company’s mission is to provide women with superior minimally-invasive, non-surgical product technologies, accessible in the office, improving patient care and overall health economics focused on servicing the reproductive health needs for those seeking solutions for infertility issues (FemaSeed® and FemVue®) or permanent birth control (FemBloc®). The Company currently operates as one segment with an initial focus on servicing the reproductive health needs for those seeking solutions for infertility issues or permanent birth control. Femasys has an expansive intellectual property portfolio which covers both utility and design patents in the U.S. and significant ex-U.S. markets for each product initiative. Femasys has taken concepts internally conceived and protected through development, including domestic and foreign regulatory approvals, and production, through in-house manufacturing. The Company received approval to sell FemaSeed, a solution which enables directed intratubal insemination to improve on historic intrauterine insemination (IUI) and provides a lower cost and safer option to in vitro fertilization (IVF) methods, from Health Canada, the Public Health Agency of Canada (Health Canada) in April 2023. In September 2023, the Company received 510(k) clearance from the FDA for FemaSeed intratubal insemination to market in the United States. A pivotal clinical trial was still ongoing at the time of receiving regulatory clearance, however, enrollment was completed in November 2023. In June 2024, the Company received European Union Medical Device Regulation (EU MDR) certificates and CE Mark certification for four products: FemaSeed, FemVue, FemCerv® and FemCath®. FemVue, a solution that enables fallopian tube assessment with ultrasound as an alternative to the radiologic approach (hysterosalpingogram) for the diagnosis of infertility, is approved for sale in the U.S., Japan, and Canada. FemCerv is a solution for complete tissue sampling with minimal contamination of the endocervical canal in a virtually pain-free procedure as an alternative to the single biopsy method for diagnosis of cervical cancer and is approved for sale in the U.S. and Canada. FemCath, allows for selective evaluation of an individual fallopian tube as an alternative to the traditional intrauterine catheter that is undirected, is approved for sale in the U.S. and Canada. In August 2024, the Company announced receipt of CE Mark certification and product approval from Health Canada for our compact, eco-friendly FemVue® MINI for fallopian tube assessment. In September 2024, the Company announced receipt of 510(k) clearance from FDA for FemChec®, a controlled contrast generating device. The Company received CE mark approval for FemChec in September 2024. FemBloc®, the Company’s solution for permanent birth control, is based on the Company’s platform technology for delivery and in June 2023 Femasys received FDA approval of our IDE to evaluate the safety and efficacy of FemBloc, our non-surgical, non-implant, non-hormonal in-office solution for permanent birth control in a pivotal clinical trial. In August 2023 Femasys announced the initiation of enrollment in the FINALE [Prospective Multi-Center Trial for FemBloc Intratubal Occlusion for TranscervicAL Permanent Birth Control] pivotal trial designed to evaluate the safety and efficacy of FemBloc. This prospective, multi-center, open-label, single-arm study design includes pregnancy rate as the primary endpoint, which will be analyzed once 401 women have relied on FemBloc for one year for permanent birth control. In addition, the study is designed as a roll-in beginning with enrollment of 50 women for a clinical readout primarily of preliminary safety data prior to enrolling the remaining subjects. An interim analysis of clinical data endpoints is planned once 300 women have used FemBloc for permanent birth control for one year. Follow-up will continue annually for five years post-market.
Basis of Presentation	Basis of Presentation The Company has prepared the accompanying condensed financial statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to these rules and regulations. These condensed financial statements should be read in conjunction with the Company’s audited financial statements and footnotes related thereto for the year ended December 31, 2023 included in our Annual Report on Form 10K filed with the SEC on March 28, 2024 (the Annual Report). There have been no material changes to the Company’s significant accounting policies described in Note 2 to the financial statements included in the Annual Report. In the opinion of management, the unaudited financial statements include all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the Company’s financial position and the results of its operations and cash flows at the dates for periods presented. The results of operations for such interim periods are not necessarily indicative of the results to be expected for the full year.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting periods. Estimates for these and other items are subject to change and are reassessed by management in accordance with U.S. GAAP. Actual results could differ from those estimates.
Liquidity	Liquidity As of September 30, 2024, the Company had cash and cash equivalents of $7,611,210. The Company plans to finance its operations and development needs with its existing cash and cash equivalents, additional equity and/or debt financing arrangements, and revenue primarily anticipated from the sale of FemaSeed and FemVue to support the Company’s research and development activities, primarily focused on FemBloc. There can be no assurance that the Company will be able to obtain additional financing on terms acceptable to the Company, on a timely basis, or at all. If the Company is not able to obtain sufficient funds on acceptable terms when needed, the Company’s business, results of operations, and financial condition could be materially adversely impacted. For the nine months ended September 30, 2024, the Company generated a net loss of $13,692,944. The Company expects such losses to increase over the next few years as the Company advances FemBloc through clinical development if and until FDA approval is received and is available to be marketed. The financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has incurred net operating losses in every year since inception and has an accumulated deficit as of September 30, 2024 of $122,074,573 and expects to incur additional losses and negative operating cash flows for at least the next twelve months. The Company’s ability to meet its obligations is dependent upon its ability to generate sufficient cash flows from operations and future financing transactions. Although management expects the Company will continue as a going concern, there is no assurance that management’s plans will be successful since the availability and amount of such funding is not certain. Accordingly, substantial doubt exists about the Company’s ability to continue as a going concern for at least one year from the issuance of these financial statements. The accompanying financial statements do not include any adjustments to reflect the possible future effects on the recoverability of assets or the amounts and classifications of liabilities that may result from the possible inability of the Company to continue as a going concern.
