Contraceptive Methods

The prevention of pregnancy remains an important part of the practice of medicine. Contraception can occur at a number of points in the basic reproductive biological process and through a number of contraceptive product options. Pharmacists are health care providers appropriately positioned to assist patients in suitable contraceptive product selection based on their personal situations and lifestyles. This article provides an overview of available products for prevention of pregnancy and associated risks and benefits. Contraceptive products are categorized by their hormonal content and method of action. Hormonal options include oral contraceptive pills, contraceptive patch, implants, injection, intravaginal, and intrauterine devices. Barrier products prevent pregnancy by creating a physical obstacle to the successful fertilization of an egg by sperm. All products and methods are associated with benefits and potential complications that must be considered as patients, and health care providers select the most satisfactory option.

Why do couples refuse or discontinue ART?

The first child born after in-vitro fertilisation, (IVF)-treatment, just passed its 26th birthday in July 2004. Since that birth-assisted reproduction techniques (ART) became a practicable technology, they had been used all over the world, and more than 2 million children were born after IVF-treatment. Despite all success in this field, ART is neither accepted nor used for all infertile couples, although this might be the only possibility of becoming pregnant. Two different kinds of ART refusal are distinguishable: the primary refusal being for financial, psychosocial, moral, ethical and medical reasons including the risk of severe ovarian hyperstimulation syndrome, the risk of multiple pregnancies and the risk of malformations. The secondary refusal includes dropouts after one or more unsuccessful IVF-treatments mainly influenced by the outcome of previous cycles (prognostic factors: oocyte and embryo count, embryo quality, females age) associated with psychological and emotional aspects. However, financial factors seem to be the most potent reasons for ART-refusal.

Oral contraceptives: current status

During the past four decades, oral contraceptives have remained a safe and effective method of birth control. Reductions in the estrogen and progestin dosages have significantly decreased the incidence of cardiovascular complications. The association between oral contraceptives and breast cancer appears to be primarily because of detection bias or possibly a promotional effect. Despite the changes in formulation, the problems related to side effects have not been totally solved. Because compliance and successful use is strongly affected by side effects, improvement in this area is probably the biggest challenge faced by developers of oral contraceptives. It is also clear that there are a growing number of significant noncontraceptive benefits that accrue in oral contraceptive users. Unfortunately, many women do not know about these benefits. Thus, one of the issues that providers need to continue to address is how to provide better information about oral contraceptives and contraception in general to patients.
