                                 PROXY STATEMENT

                          -----------------------------


INFORMATION CONCERNING SOLICITATION AND VOTING

     The enclosed  proxy is  solicited on behalf of the Board of Directors  (the
"Board") of Human  Pheromone  Sciences,  Inc.,  a  California  corporation  (the
"Company"). The proxy is solicited for use at the annual meeting of shareholders
(the "Annual  Meeting") to be held at 10:00 a.m. local time on June 20, 2002, at
the offices of Heller Ehrman White & Mc Auliffe,  275  Middlefield  Road,  Menlo
Park,  California.  The  approximate  date on which  this  proxy  statement  and
accompanying notice and proxy are being mailed to shareholders is May 15, 2002.

Record Date and Shares Outstanding

     Only  shareholders  of record at the close of business on May 3, 2002,  are
entitled to notice of, and to vote at the Annual Meeting and any adjournments or
postponements  thereof.  At the close of business on that date,  the Company had
outstanding  3,429,839  shares of Common  Stock,  1,433,333  shares of Series AA
Preferred  Stock  (which are  entitled  to 613,945  votes) and 17,448  shares of
Series BB Preferred  Stock (which are entitled to 732,816  votes).  Holders of a
majority  of the  outstanding  shares of common  and the  outstanding  shares of
preferred  stock of the  Company,  either  present  in person or by proxy,  will
constitute a quorum for the transaction of business at the Annual Meeting.

Revocability of Proxies

     Any  shareholder  giving  a  proxy  in the  form  accompanying  this  proxy
statement has the power to revoke the proxy prior to its  exercise.  A proxy can
be revoked by an instrument of revocation  delivered prior to the Annual Meeting
to the Secretary of the Company,  by a duly executed  proxy bearing a later date
or time  than the date or time of the  proxy  being  revoked,  or at the  Annual
Meeting  if the  shareholder  is  present  and  elects to vote in  person.  Mere
attendance at the Annual Meeting will not serve to revoke a proxy.

Voting and Solicitation

     On all matters that come before the Annual  Meeting,  holders of the Series
AA  Preferred  Stock are  entitled  to 1/3 of a vote for each share of Series AA
Preferred  Stock held and holders of the Series BB Preferred  Stock are entitled
to 42 votes  for each  share of  Series  BB  Preferred  Stock  held;  all  other
shareholders  are  entitled to one vote for each share held.  In the election of
Directors,  the holders of Series AA  Preferred  Stock are entitled to elect one
director,  and the holders of Series BB Preferred  Stock and Common Stock voting
together as a single class elect the remaining four  directors.  Mr. Kaufman has
been nominated for election by the holders of the Series AA Preferred Stock, and
the other four  nominees  have been  nominated for election by holders of Common
Stock and Series BB Preferred.

     A shareholder has the right to request  cumulative  voting for the election
of directors by giving notice of such shareholder's  intention to cumulate votes
at the meeting prior to the voting.  Cumulative  voting allows a shareholder  to
cast that number of votes which  equals the number of directors to be elected by
such  shareholder  multiplied  by the  number of votes the  Shares  held by such
shareholder are entitled to and to distribute  those votes among the nominees as
the shareholder may choose.  However,  no shareholder  shall be entitled to vote
for more than one  candidate to be elected by the Series AA  Preferred  Stock or
more than four candidates to be elected by holders of Common Stock and Series BB
Preferred,  and  votes  may not be cast  in  favor  of a  candidate  unless  the

                                      -2-




candidate's  name has been  placed in  nomination  prior to the  voting.  In the
election of Directors, the candidate receiving the highest number of affirmative
votes of the Series AA Preferred Stock and the four other  candidates  receiving
the highest number of affirmative votes of the Series BB Preferred Stock and the
Common  Stock  represented  and  voting at the  Annual  Meeting  will be elected
directors.

     Abstentions and broker  non-votes will be counted in determining  whether a
quorum is present at the Annual Meeting.  Generally,  abstentions are counted as
votes  against a proposal for purpose of  determining  whether or not a proposal
has been approved, whereas broker non-votes are not counted for such purpose.

     The  Company  will  bear  the  entire  cost  of   solicitation,   including
preparation,  assembling and mailing this proxy  statement,  the proxies and any
additional material,  which may be furnished to shareholders.  The Company will,
upon request,  reimburse the reasonable charges and expenses of brokerage houses
or other  nominees  or  fiduciaries  for  forwarding  proxy  materials  to,  and
obtaining  authority  to  execute  proxies  from,  beneficial  owners  for whose
accounts they hold shares of Common Stock. The original  solicitation of proxies
by mail may be supplemented by telephone,  telegram and/or personal solicitation
by directors,  officers or employees of the Company. No additional  compensation
will be paid for such services.

                                      -3-

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

     The following table sets forth certain information regarding the beneficial
ownership  of the  Company's  Common  Stock  (including  shares of Series AA and
Series BB Preferred Stock, on an as-converted to Common Stock basis) as of March
31,  2002 by: (i) each  person who is known by the  Company to own  beneficially
more  than 5% of the  outstanding  shares  of  Common  Stock;  (ii)  each of the
Company's executive officers named in the Summary Compensation Table; (iii) each
of the Company's directors;  and (iv) by all directors and executive officers as
a group.  In computing the number of Shares  beneficially  owned by a person and
the  percentage  of ownership of that person,  shares of Common Stock subject to
options held by that person that are currently exercisable or exercisable within
60 days of March 31,  2002 (see  notes (1) and (6) for  exceptions)  are  deemed
outstanding. Such shares, however, are not deemed outstanding for the purpose of
computing  the  percentage  ownership of each other  person.  The  percentage of
beneficial ownership is based on 3,429,839 shares of Common Stock outstanding as
of March 31, 2002. Except as otherwise indicated,  the Company believes that the
beneficial owners of the securities listed below, based on information furnished
by such owners, have sole investment and voting power with respect to the Common
Stock shown as being beneficially owned by them:

Board Compensation

     Directors  currently are not compensated for attending Board meetings,  but
are  reimbursed  for their  reasonable  expenses  incurred  in  attendance.  The
Company's  Non-Employee  Directors'  Stock Option Plan (the  "Directors'  Plan")
provides for the automatic grant of 8,333 shares of Common Stock if a person who
is neither an officer nor an employee of the Company and who has not  previously
been a member of the Board is elected or  appointed  director.  Each such option
will  become  exercisable  at the rate of  one-twelfth  of the  number of shares
covered  by the option  each  month  following  the grant  date,  so long as the
individual  is  serving  as a  director,  with full  vesting  over one year.  In
addition,  in June of each  year,  the  Company  is  required  to  grant to each
non-employee director a 10-year Non-Qualified Option to purchase 3,333 shares of
the Company's  Common Stock at an exercise  price equal to the fair market value
of Common Stock on the date of the grant.  These  options will vest  one-twelfth
per month  after the date of grant,  as long as the  individual  is serving as a
director,  with full  vesting over one year.  The exercise  price of all options
granted  pursuant  to the  Directors'  Plan  is the  fair  market  value  of the
Company's  Common  Stock at the time of  grant.  A total of  145,00  shares  are
reserved for issuance under the Directors' Plan.

Board Meetings and Committees of the Board

     The Board of Directors met six times in 2001. Each director participated in
at least 75% of the meetings of the Board.

     The Board of Directors has an Audit Committee and a Compensation  and Stock
Option Committee.

     The  Audit  Committee  of the Board of  Directors,  whose  members  are Mr.
Kaufman,  Dr.  Grosser,  and Mr. Marx,  held one meeting  during 2001,  with all
director members in attendance at such meeting. The Audit Committee's purpose is
to consult with the Company's independent auditors concerning their audit plans,
the results of the audit, the Company's  accounting  principles and the adequacy
of the Company's general accounting controls.


                          REPORT OF THE AUDIT COMMITTEE


     The Audit committee of the Board of Directors of Human Pheromone  Sciences,
Inc serves as the representative of the Board of Directors for general oversight
of the Company's financial accounting and reporting process,  system of internal
controls,  audit process,  and process for monitoring  compliance  with laws and
regulations.  Each of the  members of the Audit  Committee  is  independent,  as
defined under the listing  standards of NASDAQ.  The committee  operates under a
written  charter  adopted by the Board of Directors.  HPS management has primary
responsibility  for  preparing the Company's  financial  statements  and for the
Company's financial reporting process.  HPS independent  auditors,  Singer Lewak
Greenbaum & Goldstein,  LLP, are  responsible  for  expressing an opinion on the
conformity  of  the  Company's  audited  consolidated  financial  statements  to
accounting principles generally accepted in the U.S.

     In this context and in connection with the audited  consolidated  financial
statements  contained in the Company's  Annual Report on Form 10-KSB,  the Audit
Committee:

     o    reviewed and discussed the audited  consolidated  financial statements
          with the Company's  management,  including a discussion of the quality
          of the accounting principles;

     o    discussed with Singer Lewak Greenbaum & Goldstein,  LLP, the Company's
          independent  auditors,  their  judgment  as  to  the  quality  of  the
          Company's accounting principles, as well as certain matters related to
          the  conduct  of the audit,  as  required  by  Statement  of  Auditing
          Standards No. 61, Communications with Audit committees;

                                      -7-




     o    met  with  the  independent  auditors,  with  and  without  management
          present,   to  discuss  the  results  of  their   examination,   their
          evaluations  of the  Company's  internal  controls,  and  the  overall
          quality of the Company's financial reporting;

     o    reviewed the written  disclosures  required by  Independence  Standard
          Board Standard No.1, "Independence Discussions with Audit Committees,"
          discussed with the auditors their  independence from the Company,  and
          concluded  that the  non-audit  services  performed  by  Singer  Lewak
          Greenbaum &  Goldstein,  LLP are  compatible  with  maintaining  their
          independence; and

     o    instructed the independent  auditors that the Committee  expects to be
          advised if there are any subjects that require special attention.


     Based  upon the  Audit  Committee's  discussions  with  management  and the
independent   accountants,   and  upon  the  Audit  Committee's  review  of  the
representations  of  management  and  the  independent  accountants,  the  Audit
Committee  recommended  to the Board of  Directors  that the  audited  financial
statements  for the fiscal  year ended  December  31,  2001 be  included  in the
Company's  Annual  Report on Form  10-KSB,  for filing with the  Securities  and
Exchange Commission.


                                            Audit Committee:


                                            Michael D. Kaufman,
                                            Bernard I. Grosser,
                                            Robert Marx

                            Non-audit services                 $22,650


     Audit-related  services  include  review  of SEC  registration  statements,
issuance of comfort letters and consents, consultations regarding the effects of
various accounting transactions and changes in professional standards. Non-audit
services  include tax  consultations  and  preparation  of Federal and State Tax
Returns.  Neither  Singer Lewak  Greenbaum & Goldstein,  LLP nor BDO Seidman LLP
provided  any  services  related to  financial  information  systems  design and
implementation during 2001.

     As reported on Form 8-K,  dated June 15, 2001,  the Audit  Committee of the
Company authorized the termination of BDO Seidman LLP as auditors of the Company
effective  June 15,  2001.  The  reports  of BDO  Seidman  LLP on the  Company's
financial  statements  for the prior two fiscal years did not contain an adverse
opinion or a  disclaimer  of opinion  and were not  qualified  or modified as to
uncertainty, audit scope, or accounting principles.

                                      -8-




     In connection  with the audits of the Company's  financial  statements  for
each of the two fiscal  years ended  December 31,  2000,  and in the  subsequent
interim  period  through June 15,  2001,  there were no  disagreements  with BDO
Seidman LLP on any matters of  accounting  principles  or  practices,  financial
statement disclosure, or auditing scope and procedures which, if not resolved to
the  satisfaction  of BDO  Seidman LLP would have caused BDO Seidman LLP to make
reference to the matter in their report.

     As reported on Form 8-K,  dated June 29, 2001,  the Company  engaged Singer
Lewak Greenbaum & Goldstein LLP as the Company's independent auditors to replace
BDO Seidman LLP.

     The Company does not anticipate that  representatives from these firms will
be present at the annual meeting.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

          In 1991, the Company transferred to Pherin Corporation  ("Pherin"),  a
     newly formed  California  corporation,  all of the Company's  rights to its
     human  pheromone  technology  for use other than in the  consumer  products
     field,  together  with $2 million in cash, in exchange for all of the stock
     of Pherin. Upon approval by its shareholders at the Annual Meeting, held in
     August 1991, the Company  distributed to its  shareholders all of the stock
     of Pherin. Certain stockholders  identified under "Principal  Stockholders"
     above are also stockholders of Pherin.

          HPS and  Pherin  have  been  parties  to a  research  and  development
     agreement  and a supply  agreement  since  1996.  In 2001  under  the R & D
     agreement,  HPSI paid to  Pherin  $250,000  for  research  and  development
     services.  As a result of the initial third party supply agreement  entered
     into in December 1998, the Company required  significantly  more production
     of the  synthesized  human  pheromones  than were  needed  in the past.  In
     January 1999, HPS and Pherin  contracted with two independent  laboratories
     to manufacture  kilogram  quantities of the  synthesized  human  pheromones
     under the  direction  of  scientists  working on behalf of the  Company and
     Pherin.  One of these  laboratories  was  capable of  supplying  all of the
     pheromone needs of the Company in the year 2001.
