The aim of the study was to assess patient, treatment and cycle characteristics in relation to the risk of multiple conception following ovulation induction in order to reduce the prevalence of this complication of treatment. We performed a retrospective analysis of 208 pregnancy cycles achieved in the Middlesex Hospital outpatient fertility unit. These pregnancies were achieved in 175 anovulat...

the present study was designed to investigate the impact of exogenous administration of gnrh (receptal vet®, intervet pharmaceuticals ltd., india) on serum progesterone profile and conception rates during mid luteal phase of estrous cycle in buffaloes. estrus was induced using cyclix 2 ml. i/m. (intervet india pvt. ltd., india) and animals were bred naturally during observed estrus. the buffalo...

The treatment of infertility has developed rapidly, and the anaesthetist may be involved in many aspects of the patient’s treatment, which may be complex. The harvesting of oocytes needs to take place within a defined period of time, or ovulation may have occurred and oocytes will be lost. Couples presenting for infertility treatment are generally anxious and often the women are emotional at th...

Genetic increases in twinning of cattle could result in increased frequency of triplet or higher-order births. There are no estimates of the incidence of triplets in populations with genetic levels of twinning over 40% because these populations either have not existed or have not been documented. A model of the distribution of litter size in cattle is proposed. Empirical estimates of ovulation ...

Analysis of routinely published abortion and fertility data for England and Wales between 1968 and 1980 shows that the age-specific abortion rates increased from 1968 until about 1973 when the rates peaked for all ages; rates then declined until 1977 but have subsequently returned to higher levels. Two factors are implicated: (1) the recent changes are related to parallel changes in the fertili...

Philosophy Compass. 2018;e12494. https://doi.org/10.1111/phc3.12494 Abstract How should knowledge be analyzed? Compositionally, as having constituents like belief and justification, or as an atomic concept? In making arguments for or against these perspectives, epistemologists have begun to use experimental evidence from developmental psychology and developmental linguistics. If we were to conc...

Two experiments were performed to determine the effectiveness of different progestogens contained in intravaginal devices, different doses of eCG and subsequent hCG treatment on the reproductive performance of estrus-induced mature Lori ewes. In the first experiment, 88 ewes were allocated into two groups, and were treated with either fluorogestone acetate (FGA) sponges or Controlled Internal D...

the exchange rate unification is one of the most important instruments of economic adjustment, which is used in many countries. this paper shows the effects of the exchange rate unification on price level (inflation), gross domestic production (gdp), non-oil exports, private conception, government expenditure and stock of money. the data, is used related to the period 1959-2000. to analyze the ...

backgrownd: studies in regions with seasonal climatic variations have revealed a correlation between human natural conception and birth rates. holidays and other cultural activities probably have influence on conception, but the ambient temperature and emotional influences on the female hormones related to fertility may play an important part in the seasonal variation in conception. objectives:...

Service-sire conception rate (SCR) evaluations were implemented for the United States in August 2008. Only inseminations from the most recent 4 yr of breeding records are used for SCR evaluations, and all inseminations must have occurred ≥ 70 d before the data submission deadline for an evaluation. In April 2012, edits for SCR were modified so that all inseminations must have occurred ≥ 70 d be...
