Evaluation of the postcoital test in cycles involving exogenous gonadotropins

Abstract

To evaluate the hypothesis that a postcoital test, optimally performed in the periovulatory period of cycles in which gonadotropin-induced superovulation was used, correlates with cycle fecundity. Of 1135 total consecutive cycles, 367 first cycles were analyzed from the reproductive endocrinology and infertility service of a university medical center. This referral population had a mean age of 34.6 years for the female partner, a nulliparity rate of 81%, and a mean length of infertility of 4.8 years. Postcoital tests were performed 36-40 hours after hCG administration in gonadotropin-stimulated cycles. Clinical pregnancy was defined as fetal cardiac activity as seen on transvaginal ultrasound examination. Couples with no sperm observed per high-power field in the cervical mucus achieved a 16% fecundity rate (21 pregnancies in 129 cycles), one to ten sperm a 18% fecundity rate (28 pregnancies in 154 cycles), and more than ten sperm a 15% fecundity rate (13 pregnancies in 84 cycles). There was no significant difference between groups (n = 367, P = .85); the power to detect a statistically significant difference was .82. As validation of optimal cervical mucus, fecundity rates were compared with these postcoital test values across...Continue Reading

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.
