Head of Department, Physiology
Email: 

Dr. Oyeyipo is a Senior Lecturer, the pioneer full-time staff and current Head of Department of Physiology.  He obtained his Ph.D from the University of Ibadan, Nigeria in 2014 and won a postdoctoral fellowship the same year at Stellenbosch University, South Africa. He was admitted as a fellow of the Institute of Basic Medical Sciences (UK) in 2015. Dr. Oyeyipo was on internship at the Centre for Reproduction Medicine and Andrology, University of Muenster, Germany in 2012 and holds other academic and professional qualifications, obtained from the Nigerian Institute of Management, Earth Institute at Columbia University and Johns Hopkins School of Public Health. He is an active member of several professional associations within and outside Nigeria and has won several research and academic grants.  Dr Oyeyipo has attended and presented over 25 scientific papers in local and international conferences and has over 35 publications to his credit.

As an academic staff in the University, I am actively involved in teaching, invigilating, assessing and collating students’ results. I am also involved in research from the stage of conceptualization of ideas, publication of findings and ensuring that studies translates into community development through enlightenment talks and counselling.
As Head of Department, I coordinate the day to day administrative and academic activities and oversees the conduct of both staff and students in the Department. I also organise all lectures and coordinate all examination as the chief examiner.

My research activities focus mainly on male reproductive toxicity. In the last decade, I have investigated the effects of some pharmacological agents such as antimalarial agent, oral contraceptives, antidepressant and additives alongside their mechanisms of action with implication for fertility/infertility in both in vivo and in vitro experimental models.
My studies established that Nicotine, Norgestrel, Quassin, Arthemeter and Amitriptyline inhibited sperm functions in animal and human studies. Inhibition of testicular steroidogenesis was the major focus of their actions. They also impacted negatively on male reproductive functions through hypothalamao-hypophyseal- gonadal axis. This could be a major factor among others, attributed for the decline in sperm quality and quantity and thus declined fertility potential in man over the last century.

Mr Adeleke Opeyemi Samson is a lecturer in the Department of Anatomy, College of Health Sciences, Osun State University, Osogbo. He joined Osun State University work force in the year 2015 as an Assistant Lecturer. He had his first degree (B.Tech) in Anatomy (Second Class upper division) from Ladoke Akintola University of Technology Ogbomoso and Masters of Science (M.sc.) degree in Anatomy from University of Ilorin, Ilorin, Kwara State, Nigeria. He is currently pursuing his Ph.D. programme in the field of Reproductive Anatomy at the University of Ilorin. Mr Adeleke is a Member of Anatomical Society of Nigeria (ASN), Member, Society of Experimental and Clinical Anatomists of Nigeria (SECAN) and also Member, Red Cross Society of Nigeria.

Mr. Adeleke Opeyemi is committed:
To train students in Topography Anatomy/Macroscopic and Microscopic Anatomy knowledge that will be sufficient for them to proceed for further studies in related fields of specialization and enable them to apply the course to life situations.
To train and supervise student projects and help them to be skillful at using the basic research instruments that will make them competitive globally in the field of Anatomy.
Set and mark assignments and set examination questions as well as assessing the work and progress of students by reference to defined criteria and provide constructive feedback to students.

My area of research interest are Reproductive Biology and Endocrinology and my research so far has contributed to the establishment of the toxicity profiling of some Antipsychosis drugs (Chlorpromazine and Rawoulfia vomitoria), Antihypertensive drugs (Methyldopa and Moringa oleifera) and Chemicals/Metals (Pyrethroids and Aluminum) which are widely used drugs and chemicals. The findings of these studies have helped to establish the safety or otherwise effects of these drugs and chemicals on male fertility to the users and medical personnel. Moreover, my research so far has helped to showed high beneficiary effects of some natural products and supplements (Rauwolfia vomitoria, Moringa oleifera and Riboceine) on male fertility (as Fertility enhancer).
Some of the research work are; Sperm parameters and histopathological expression in animal model testes after exposure to Aluminum and Pyrethroids. Ameliorating effects of D-ribose-L-cysteine on the reproductive parameters; GnRH and Bax protein expression in hypothalamus and testes respectively after exposure to antipsychotic drugs; DBY gene expression in psychotic patient treated with herbal antipsychotic drugs; Steroidogenic enzymes, DAZ gene and p53 protein expression after exposure to different ranges of electromagnetic radiation from Smartphone.

 Carrying out administrative duties has assigned by the Head of the Department, some of which include student liaison officer and Department examination officer

Carrying out research that will positively impact the University and Communities at large.
