A new technique for intrauterine insemination

International Journal of Fertility
J Kremer


The 5-cm long endpiece of a soft Nelaton's catheter, ch 6-8, splinted with a rigid polyethylene cannula, proved to be a suitable instrument for intrauterine homologous inseminations. Sixty couples were treated; indications for intrauterine insemination were subfertile semen, poor postcoital test, antisperm antibodies in male or female, and unexplained infertility of more than 5 years. Seventeen pregnancies occurred, that is 28%. The best results were obtained in the group with unexplained infertility and in the group with poor postcoital tests, combined with a good result of the in vitro sperm penetration tests. Complications of the inseminations were rare. The method did not elicit sperm agglutinins in the female; however, if sperm agglutinins were already present in the female, the titre level increased after the intrauterine inseminations.

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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
