Subsequent Events [Abstract]
Subsequent Event	Note 11 – Subsequent Event During July and August 2015, Aytu closed on note purchase agreements with institutional and high net worth individual investors for the purchase and sale of convertible promissory notes with an aggregate principal amount of $5.2 million. The sale of the notes was pursuant to a private placement. Aytu intends to use the net proceeds of the offering to conduct clinical studies for both Zertane^® and RedoxSYS™ and for working capital to begin commercializing FDA-approved ProstaScint^®, as well as general corporate purposes. The notes are an unsecured obligation. Unless earlier converted, the notes will mature 18 months from their respective dates of issuance which will be on January 22, February 11 and February 28, 2017, with an option to extend up to six months at our discretion (provided that in the event Aytu exercises such extension option, the then applicable interest rate shall increase by 2% for such extension period). Aytu does not have the right to prepay the notes prior to the maturity date. Interest will accrue on the notes in the following amounts: (i) 8% simple interest per annum for the first six months and (ii) 12% simple interest per annum thereafter if not converted during the first six months. If there has not been a registration statement on Form S-1 filed with the SEC for the registration of the shares of common stock underlying the notes by the expiration of the first six-month period then (a) the interest rate will increase to 14% for the remainder of the period in which the notes remain outstanding and (b) any notes held by officers and directors of the Company will be subordinated to the remaining notes. Interest will accrue, is payable with the principal upon maturity, conversion or acceleration of the notes and may be paid in kind or in cash, in Aytu’s sole discretion. The notes are convertible at any time in a noteholder’s discretion into that number of shares of Aytu common stock equal in an amount equal to 120% of the number of shares of common stock calculated by dividing the then outstanding principal and accrued interest by $4.63. A holder of notes will be obligated to convert on the terms of Aytu’s next public offering of its stock resulting in proceeds to it of at least $5,000,000 in gross proceeds (excluding indebtedness converted in such financing) prior to the maturity date of the notes (a “Qualified Financing”). The principal and accrued interest under the notes will automatically convert into a number of shares of such equity securities of the Company sold in such financing equal to 120% of the principal and accrued interest under such note divided by the lesser of (i) the lowest price paid by an investor in such financing or (ii) $4.63. In the event that Aytu sells equity securities to investors at any time while the notes are outstanding in a financing transaction that is not a Qualified Financing, then the noteholders will have the option to convert in whole the outstanding principal and accrued interest as of the closing of such financing into a number of shares of Aytu capital stock in an amount equal to 120% of the number of such shares calculated by dividing the outstanding principal and accrued interest by the lesser of (i) the lowest cash price per share paid by purchasers of shares in such financing, or (ii) $4.63. Newbridge Securities Corporation, Member FINRA/SIPC, through LifeTech Capital, acted as sole placement agent for the institutional portion of the offering. Aytu sold the balance of the notes to individuals and entities with whom Aytu has an established relationship. For notes sold by the placement agent, Aytu paid the placement agent 8% of the gross proceeds of notes sold by the placement agent and a warrant to purchase shares of Aytu’s common stock equal to 8% of the gross proceeds of the notes sold by the placement agent divided by the price per share at which equity securities are sold in Aytu’s next equity financing, in addition to a previously paid non-refundable retainer fee of $20,000. The placement agent warrant has a term of five years, will have an exercise price equal to 100% of the price per share at which equity securities are sold in Aytu’s next equity financing, and provides for cashless exercise. On August 19, 2015, Aytu entered into a 37 month non-cancellable operating lease for new office space effective September 1, 2015. The new lease has initial base rent of $8,500 per month beginning in October 2015, with the total base rent over the term of the lease of approximately $318,000 which includes rent abatements. The Company recognizes rental expense of the facility on a straight-line basis over the term of the lease. Differences between the straight-line net expenses on rent payments are classified as liabilities between current deferred rent and long-term deferred rent.

During July and August 2015, Aytu closed on note purchase agreements with institutional and high net worth individual investors for the purchase and sale of convertible promissory notes with an aggregate principal amount of $5.2 million. The sale of the notes was pursuant to a private placement.

Aytu intends to use the net proceeds of the offering to conduct clinical studies for both Zertane^® and RedoxSYS™ and for working capital to begin commercializing FDA-approved ProstaScint^®, as well as general corporate purposes.

The notes are an unsecured obligation. Unless earlier converted, the notes will mature 18 months from their respective dates of issuance which will be on January 22, February 11 and February 28, 2017, with an option to extend up to six months at our discretion (provided that in the event Aytu exercises such extension option, the then applicable interest rate shall increase by 2% for such extension period). Aytu does not have the right to prepay the notes prior to the maturity date. Interest will accrue on the notes in the following amounts: (i) 8% simple interest per annum for the first six months and (ii) 12% simple interest per annum thereafter if not converted during the first six months. If there has not been a registration statement on Form S-1 filed with the SEC for the registration of the shares of common stock underlying the notes by the expiration of the first six-month period then (a) the interest rate will increase to 14% for the remainder of the period in which the notes remain outstanding and (b) any notes held by officers and directors of the Company will be subordinated to the remaining notes. Interest will accrue, is payable with the principal upon maturity, conversion or acceleration of the notes and may be paid in kind or in cash, in Aytu’s sole discretion.

A holder of notes will be obligated to convert on the terms of Aytu’s next public offering of its stock resulting in proceeds to it of at least $5,000,000 in gross proceeds (excluding indebtedness converted in such financing) prior to the maturity date of the notes (a “Qualified Financing”). The principal and accrued interest under the notes will automatically convert into a number of shares of such equity securities of the Company sold in such financing equal to 120% of the principal and accrued interest under such note divided by the lesser of (i) the lowest price paid by an investor in such financing or (ii) $4.63. In the event that Aytu sells equity securities to investors at any time while the notes are outstanding in a financing transaction that is not a Qualified Financing, then the noteholders will have the option to convert in whole the outstanding principal and accrued interest as of the closing of such financing into a number of shares of Aytu capital stock in an amount equal to 120% of the number of such shares calculated by dividing the outstanding principal and accrued interest by the lesser of (i) the lowest cash price per share paid by purchasers of shares in such financing, or (ii) $4.63.
