Relation between indices of semen analysis and pregnancy rate in infertile couples

Fertility and Sterility
K D SmithE Steinberger

Abstract

Both partners of 198 consecutive infertile couples were evaluated. Studies in the female included clinical evaluation of ovulation for a minimum of two menstrual cycles, investigation of tubal patency, and evaluation of sperm survival in cervical mucus. Six semen specimens were analyzed from each male. Laparoscopy, scrotal exploration, and testicular biopsies were performed as required. Where indicated, the female was treated intensively. The only therapy offered to the males was ligation of varicoceles, if present. The couples were grouped on the basis of sperm counts, total sperm counts, motile sperm counts, and total motile sperm counts, and the incidence of pregnancy was computed. Pregnancy rates of approximately 50% occurred in couples where sperm counts or total sperm counts were in the range of 5 to 60 million/ml or 25 to 200 million/ejaculate, respectively. When sperm counts were over 60 million/ml or total sperm counts over 200 million/ejaculate, pregnancy rates increased to above 70%. These observations emphasize the importance of considering infertility as a problem of a couple rather than as a specific disorder of one of the partners. These data also demonstrate a lack of direct correlation between sperm density in ...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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.
