Sterility and fecundability estimation
Journal of Theoretical Biology, 1983The percentage of steriles and the fecundability of non-steriles among a given population can be estimated by a probabilistic model from observations made on delays to first conception. The maximum likelihood method of estimation that was used takes into account all available information, though some of these observations may be incomplete due to a ...

To the Editor .—In the September issue of theArchives(110:1133, 1975), the following statement caught my attention: "Nonspecific colitis proximal to an obstructing colonic carcinoma has appeared in the surgical literature for over 20 years." Maybe that is why some of the surgical literature "stinks."

Abstract A computerized probability model of family-building, FERMOD, is described and then utilized in an investigation of relations between family planning and fecundity as applying to white couples of the contemporary United States. Models of this type that formulate reproductive performance as a stochastic process permit one to explore relations ...

Recent attempts to estimate the probability of pregnancy resulting from a single act of coitus and the length of the fertile period have depended on estimates of the mean fecundability (i.e. the probability of becoming recognizably pregnant during a single menstrual cycle) of groups of married women not using contraceptive techniques.

The evolutionary significance of multiple matings or polyandry in social insects like honeybees has been a matter of considerable debate for many years because the phenomenon does not accord with the theoretical advantages that monandry appears to offer to fitness (Hamilton 1964). Nonetheless, Oldroyd et al.

The decline of fecundity with age
Maturitas, 1988PIP: Historical studies all indicate a decline in fertility with age. The artificial insemination data from a program carried out in France since 1973 related to women whose husbands were permanently sterile because of azoospermia. During the first 2 cycles only 1 insemination was performed per cycle using frozen semen from married donors aged 45 years

As classically conceived, the idea of transcendence is self-contradictory. The subject that transcends is swept away in its transcendence; it does not transcend itself. If, instead of reducing itself to a change of properties, climate, or level, transcendence would commit the very identity of the subject, we would witness the death of its substance.
