摘要:

Conception is a matter of chance. A couple's monthly probability of conceiving naturally is known as their fecundability. The average “normal” fecundability (as a proportion) is approximately 0.2. This means that most young couples can expect to have children and will conceive within 12 months of attempting pregnancy. This article examines the causes of infertility and the results that can be achieved by conventional treatment among couples with a single cause for their infertility. The difficulties that are faced when conventional infertility treatment is applied to infertility with multiple causes or with no apparent cause are explained.

摘要:

From July 1975 to June 1985, 14 630 sera from patients in New South Wales were tested for serological evidence of leptospirosis. Among these, 361 sera contained evidence of past infections and 150 of these 361 specimens had evidence of recent or current infections. Serologically‐diagnosed cases of leptospirosis were distributed mainly in the central and eastern parts of the State.Pomona, hardjoandicterohaemorrhagiaewere the most common serovars to be detected; male abattoir workers and farmers were the most common occupational groups that were infected. An increase in seropositive cases occurred from 1981, largely due tohardjoand to a lesser extentpomonainfections among farmers. Clinical histories indicated that most cases presented as pyrexias of unknown origin or as febrile illnesses; however, four patients were reported to have presented with renal failure; three patients were reported to have presented with meningitis; and 10 patients were jaundiced at presentation.

摘要:

It is claimed that Japan has the highest incidence of pineal neoplasms in the world. To test this hypothesis, we reviewed all pineal neoplasms and third‐ventricular teratomas that were diagnosed histopathologically and treated neuro‐surgically over 10 years (1975‐1984) in Niigata City, Japan (12 patients) and in Perth, Western Australia (9 patients). The age‐standardized incidence rates per million person‐years were 0.61 for Niigata and 0.70 for Western Australia; thus, the contention that Japan has the highest incidence in the world of pineal neoplasms is not confirmed.

摘要:

Assisted conception with in‐vitro fertilization and related reproductive interventions is the only practical way of treating many infertile couples. This article examines the cost‐effectiveness of in‐vitro fertilization procedures, the importance of not isolating these procedures from the general management of infertility, and the urgent need to clarify the ethical justification for research on the early human embryo.
