Summary
Brazil
Area of Science:
- Public Health
- Sexual Health
- Reproductive Health
Background:
- Brazil's Ministry of Health initiated a nationwide female condom (FC) introduction in public health services (1998-99).
- A preparatory study was conducted across 20 sites in six cities to assess FC feasibility.
Purpose of the Study:
- To evaluate the adoption, acceptability, and impact of the female condom (FC) in Brazilian public health settings.
- To determine factors influencing FC use and effectiveness in promoting safer sex practices.
Main Methods:
- Training clinic health workers to conduct the study and educate participants.
- Recruiting 2382 women volunteers to use the FC and attend 15-day and 90-day follow-ups.
- Assessing FC usage, user satisfaction, and changes in barrier method use at last intercourse.
Main Results:
- At 90-day follow-up, 1453 women had used the FC, with 1296 liking it and desiring continued use.
- Barrier method use (male or female condom) at last intercourse more than doubled from baseline (33%) to 90 days (70%).
- Clinics with active health education showed higher follow-up rates and FC acceptability.
Conclusions:
- Introduction of the FC in Brazilian public health centers can achieve high initial adoption and sustained use.
- The female condom (FC) is effective in increasing safer sex practices.
- Health education levels and clinic type significantly influence the success of future FC programs.

Birth Control Methods
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although vasectomy...
External Female Genitals
The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more pigmented, and hairless. While the...
Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Vagina
The vaginal canal is a tubular structure averaging about 10 cm in length that acts as the entryway to the female reproductive system and the passageway for menstrual flow and childbirth. The interior walls of the vagina exhibit concentric folds called rugae and are topped by an area known as the fornix, which connects with the protruding cervical portion of the uterus. This canal is comprised of an external fibrous layer, a muscular middle layer, and an inner lining with mucosal rugae, which...
Socioemotional Experience and Gender Development
Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...
Infertility in Females
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
