A male-sterile insertion in the mouse
Cytogenetic and Genome Research, 1983Is(7;l)40H was found in the daughter of a male mouse given spermatozoal X-irradiation. It is a non-inverted insertion of about half of chromosome 7 into chromosome 1, generating a long somatic marker chromosome. Breakpoints are in bands IB, 7B1, and 7F1; linkage tests show that these breakpoints are about midway between <i>fz </i>and <i ...

Abstract Male and female sterilization is used in many countries worldwide as a permanent method of contraception. Failure rates for female sterilization are affected by age at sterilization and by the method of tubal occlusion. Laparoscopic sterilization has low complication rates but is not available in parts of the developing world due to the lack

Cytoplasmic inheritance is of theoretical importance-it may be of even greater practical importance, for, when it involves malesterility-as in many instances it does-it may make hybridization easier. It may also make possible the use of heterosis in plants otherwise difficult to hybridize.

Abstract Using Farris' technique of examining semen specimens for determining the potential degree of the male's fertility, 200 semen analyses were done on 178 husbands in 178 unselected infertile couples. It was found that 123, or 69 per cent, of these men had an absolute motility of 80,000,000 or more sperm and therefore were potentially fertile ...

Abstract Male sterility research has been directed toward two goals: identifying genes required for the pollen development pathway and, more practically, identifying genetically stable lines that can be used in hybrid seed-breeding programs. The present resurgence of interest in male sterility remains true to these goals, but in addition seeks a ...

Surgical Correction of Male Sterility
Journal of Urology, 1961A series of 157 patients were subjected to surgical exploration to d etermine the mechanical causes of male sterilty. Factors causing sterility included congenital absence of the epididymes surgical division of the vasa deferentia for sterilization purposes and gonococcus or some unspecific pyogenic organism causing bilateral epididymitis.

Abstract Male and Female sterilization are permanent methods of contraception. While female sterilization is far more common than male sterilization, vasectomy is safer, simpler, about half the cost of female sterilization, and is more effective. Female sterilization, in the form of laparoscopic sterilization is the more common procedure being done ...
