National Blood Service Refutes "Scientifically Inaccurate" Claims Linking Ejaculation to Blood Loss

The National Blood Service (NBS) of Ghana has officially debunked widespread misconceptions suggesting that ejaculation during sexual activity leads to a depletion of a man’s blood volume. In a formal statement released on August 20, 2026, the NBS characterized these claims as "scientifically inaccurate" and potentially harmful to public health awareness. The intervention, signed by the NBS Chief Executive Officer, Dr. Shirley Owusu-Ofori, aims to stem the tide of misinformation that has circulated regarding the physiological relationship between reproductive health and the circulatory system.

Central to the correction is the biological distinction between the fluids involved. The NBS clarified that semen and blood are entirely separate fluids produced by distinct biological systems within the human body. Specifically, the Service rejected a popular but erroneous mathematical comparison suggesting that the volume of a single ejaculation could be equated to the loss of a pint of blood. According to the NBS, ejaculation does not deplete blood supply, and there is no physiological mechanism that would cause sexual activity to diminish the body's blood reserves in the manner described by recent public commentary.

The Service’s response was prompted by misleading statements made during a "Prime Morning" television discussion, as well as a subsequent article that amplified these claims. By addressing these specific instances, the NBS highlighted the dangers of health misinformation, which can create unnecessary fear or influence behaviors related to sexual and prostate health. The Service emphasized that spreading such unfounded assertions could mislead the public and create a false sense of medical crisis regarding routine biological functions.

Moving forward, the National Blood Service has urged the public and media organizations to verify health-related information with qualified medical professionals before dissemination. Correcting these misconceptions is vital for maintaining public confidence in health systems and ensuring that men have accurate information regarding their reproductive well-being. The NBS reaffirmed its commitment to providing evidence-based information to safeguard the nation’s health and encouraged citizens to rely on scientific facts rather than myths.
