Fallopian tube sperm perfusion: first clinical experience

Human Reproduction
J A KahnK Molne


We have developed an insemination method using a large (4 ml) volume of the inseminate. This method incorporates ovarian stimulation, isolation of an optimal number of motile spermatozoa and, finally, Fallopian tube sperm perfusion (FSP). In a clinical study, 139 couples with various causes of infertility, had a total of 239 treatment cycles. The pregnancy rate per treatment in groups with endometriosis, ovulation disorders, tubal impairment, combined male and female factors and subnormal sperm quality were low, ranging from 2.7% to 7.7%. In patients with unexplained infertility, the pregnancy rate per treatment was 26.9% and for this group, the pregnancy rate in the first treatment cycle was 37.3%. In the cervical hostility group, two pregnancies occurred after five treatments. FSP seems to be a favourable treatment for couples with cervical hostility or unexplained infertility. About half of the women in these groups conceived after three treatment cycles. FSP is easier to perform and is less expensive than other methods of assisted procreation, such as in vitro fertilization and gamete intra-Fallopian transfer.

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.

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.

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.


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.
