BACKGROUND On January 1, 2000, Texas began enforcement of a law that requires physicians to notify a parent of a minor child seeking an abortion at least 48 hours before the procedure. METHODS We assessed changes in the rates in Texas of abortions and births (events per 1000 age-specific population) before enforcement of the parental notification law (1998 to 1999) and after enforcement (2000...

This study was designed to test the treatment with prostaglandin F2α (PGF2α) plus equine chorionic gonadotrophin (eCG) and GnRH 48 h later (PEG protocol) followed by fixed-time AI (FTAI) in dairy cows with silent ovulation (cows with a mature corpus luteum and no signs of estrus detected in the preceding 21 days). In Experiment I, ovulation following the PEG protocol monitored in 24 cows with s...

Detection of estrus (heat) is often cited as the most costly component and undoubtedly, the major limiting factor to the success of A.I. programs on many dairy farms. Incorrect detection of estrus is related to loss of income due to extended calving intervals, milk loss, increased veterinary cost, increased heifer rearing cost, and slowed genetic progress. To achieve excellent heat detection, m...

Purebred Hampshire, Duroc and crossbred (H x D, D x H) boars were studied to evaluate reproductive characteristics. One hundred seventeen boars were castrated at 7Y:! months of age to evaluate testicular weights and sperm numbers. Seventy-eight additional boars were studied to evaluate conception rate and embryo numbers when mated to Yorkshire gilts. Rate of gain and backfat probe were also ava...

OBJECTIVE To assess mid-luteal estradiol (E2) levels in poor and good responders and determine its effect on the outcome after intracytoplasmic sperm injection (ICSI). METHODS The current study was carried out in females who underwent ICSI from June 2011 to September 2013 in "Islamabad Clinic Serving Infertile Couples". They were categorized into good and poor responders on the basis of femal...

OBJECTIVES To determine whether a history of a previous aneuploid conception increases the rate of aneuploidy among women having preimplantation diagnosis (PGD). METHODS Preimplantation embryos were tested for aneuploidy using FISH probes specific for chromosomes 13,15,16,17,18,21,22,X and Y. Using logistic regression to control for maternal age, we compared the rates of aneuploidy and other ...

The aim of the present study was to study the effect of parity on the efficacy of Ovsynch protocol in buffalo. Out of 686 buffalo heifers (HE) and 273 cows (BC), 8 heifers and 9 cows were used to monitor and evaluate ovarian follicular dynamics and serum progesterone profile during this protocol while the rest of animals were used to compare the conception rate following the application of this...

The aim of the present study was to determine the conception rate and litter size in sows after fixed time intra-uterine insemination using frozen-thawed boar semen in a commercial swine herd in Thailand. Sixty-nine Landrace multiparous sows were randomly allocated into two groups, including control (n=36) and treatment (n=33). The control sows were inseminated with extended fresh semen (3 × 10...

We study whether the relationship between the state unemployment rate at the time of conception and infant health, infant mortality and maternal characteristics in the United States has changed over the years 1980-2004. We use microdata on births and deaths for years 1980-2004 and find that the relationship between the state unemployment rate at the time of conception and infant mortality and b...
