Contraceptive vaginal ring--a rising star on the contraceptive horizon

Abstract

Two studies were carried out at AIIMS to judge efficacy, side-effects and acceptability of the contraceptive vaginal ring, a Silastic ring with an inner core containing 6.0 mg levonorgestrel mixed with Silastic and an outer core of Silastic only. It releases levonorgestrel at a constant rate of 20 micrograms/day and remains effective for 90 days. The first study of 50 women lasted for 12 months and the second study of 46 women lasted 24 months. Menstrual irregularity in 36% of women was the commonest reason for discontinuation. The majority of women experienced menorrhagia or irregular spotting per vaginum. Vaginal irritation or increased vaginal discharge was the second commonest reason for discontinuation and was noted in 23% of subjects. Repeated spontaneous expulsions accounted for discontinuation in 6% of subjects. No method-related failure was noted in the study. Follow-up study revealed users to be happier with the ring than with any other method and no spouse complained of feeling the ring during coitus. With its ease of administration, absence of gastrointestinal side-effects and a high success rate, the contraceptive vaginal ring is a promising contraceptive method for the last decade of the 20th century.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
