(1) Multiple spawnings of individual females were also observed during the spawning period affecting the relative fecundity of the eggs.
(2) Haematological and blood biochemical changes in the sheep, as well as fecundity of gastrointestinal nematodes, suggested the hosts were immunosuppressed.
(3) Effect of microsporidiosis on the fecundity of hosts A. c. caspius was studied.
(4) Fecundability was only 12% lower for women in the 30-39 year age interval than for women up to 29 years of age.
(5) Data in relation to evolution cycle, period between emergency of adults and first oviposition, fecundity, fertility, amount of blood ingested and fast resistance, are presented.
(6) We conclude that cycle fecundity rates and cumulative pregnancy rates are significantly greater using a combination of hMG and IUI compared with either modality alone in the treatment of male factor, cervical factor, endometriosis, or unexplained infertility.
(7) A model of functional epistasis is proposed in which it is assumed that coupling and repulsion genotypes differ in metabolic efficiency and thus in development time and net fecundity.
(8) We show by genetic crosses that each gene makes an equivalent contribution to the fecundity and fertility of the female and they do not individually provide unique functions to the embryo.
(9) were significantly higher in Booroola ewes containing a major fecundity gene (FF and F+ ewes) compared to those values in Booroolas with no copy of the gene (++ animals; P less than 0.025).
(10) Fecundity among genotypes was not different, although there was an effect on the total number of offspring suggesting differences in egg-to-adult survivorship.
(11) The higher fecundability of more recent cohorts is the most consistent observation.
(12) Electrophoretic partition of the semen plasma of dogs with fecundity disturbances also showed the presence of three fractions, whose migration path and protein concentration are identical with those found in the semen plasma of fertile dogs.
(13) mortality was high), while the nymphal instars showed an adverse effect on ecdysis and adults which emerged from the treated last nymphal instar were characterized by high mortality, abnormal behaviour and reduced fecundity and viability.
(14) Thus, parity had little effect on fecundity in aging females, whereas the cessation of regular ovulatory cycles during aging greatly decreased both the incidence of fertility and the litter size.
(15) Neither sex nor the age of the host was found to influence the fecundic life span or the survival of female adult worm.
(16) The viabilities and fecundities of these same lines were determined by a segregation test using the SM5 balancer chromosome.
(17) The numbers of vitellogenic oocytes in the ovary during the entire study also suggested that atresia of vitellogenic oocytes does not play a prominent role in determining fecundity.
(18) Fecundability of 104 healthy women attempting to become pregnant was halved by consumption of the equivalent of 1 cup of brewed coffee or more daily.
(19) A possible relation between prenatal exposure to cigarette smoking and adult fecundability in women was explored, with the use of data from a prospective study of 221 North Carolina couples.
(20) The processes, connected with the population's reproduction fecundity and the birth number play a great part in the health formation of different populations.
