Chemical inducers of ovulation are frequently used to reestablish a normal hypothalamic-ovarian function in the sterile woman. At present, several types are available and it is useful to evaluate comparatively their efficacy. In this paper we present our results in 396 cases treated with some of these drugs. Clomiphene citrate was administered to 307 patient. Ovulation was obtained in 85.99% and pregnancy in 35.50%. There were 16 abortions (14.68%) among the 109 pregnancies obtained. Cisclomiphene was used in 11 cases. The ovulation rate was 81.81%, with 54.5% of pregnancies. Thirty-eight patients were treated with Cyclophenil. Ovulation was obtained in 71.05% of the cases and pregnancy in 23.68%. In forty cases Tamoxifen was administered: the ovulation rate was 95% and the pregnancy rate was 35%, but the abortion rate was 35%. Tolerance was good with all medications. They had similar adverse side effects (mild and rare). None produced overstimulation. With Cyclophenil and specially with Tamoxifen the cycles were longer. The incidence of abortion in the 131 pregnancies obtained was 14.68% with Clomiphene; none with Cisclomiphene; 11.11% with Cyclophenil, and 35.10% with Tamoxifen. We conclude that Clomiphene is the drug which g...Continue Reading

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.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration
