Which bacterial sti causes more complications in women than in men?
MrMuchimi

The correct answer is option (A) Chlamydia.

A typical sexually transmitted illness is chlamydia. Both men and women are susceptible. However, compared to men, women are typically more negatively impacted by its consequences.

Symptoms and reasons for Chlamydia

  • Chlamydia symptoms are sometimes mistaken for those of other diseases that afflict women.
  • Some signs, such vaginal ulcers, are difficult to see, making the infected unaware that they have the disease.
  • If addressed, this can result in even more serious issues including pelvic inflammatory disease, which then might have an impact on fertility.
  • It may harm a woman's reproductive system permanently. Later it becomes challenging for women to get pregnant as a result. Additionally, chlamydia can result in an ectopic pregnancy that may be fatal.

critically evaluate the role of a persons rights and responsibilities when executing freedom of expression during verbal interpe
Stells [14]

A person does have basic human rights and one is the freedom of expression. Though this is the case, we should understand that our right to freely express ourselves (from political to religious views), it does not necessarily give us the right to impede another person’s. A play with words can easily hurt or even harass other people, and in return may be a form of human right violation.
