Performance of 1/2-Suffolk, 1/2-Rambouillet (Western) and 1/2-Suffolk, 1/4-Rambouillet, 1/4-Finnsheep (1/4-Finn) ewes was compared in three different lamb production systems over 3 yr. System 1 (56 ewes) involved late fall lambing over 84 d. System 2 (51 ewes) involved January and February lambing for 60 d. System 3 (47 ewes) involved March and April lambing for 45 d. Pregnancy rates for yearli...

The influence of thawing procedures on fertility of semen in .25-ml Continental 3 straws was investigated in a series of eight trials utilizing 1,634 cows. The following pregnancy rates were obtained: Trial 1, 38.6 vs 23.0% (P<.05) for semen thawed in 75 C water/7 sec vs "in the cow"; Trial 2, 29.7 vs 22.2% (P>.10) for semen thawed in 75 C water/7 sec vs "in the cow"; Trial 3, 82.8 vs 61.6% (P<...

Fertility awareness based methods (FABMs) can be used to ameliorate the likelihood to conceive. A literature search was performed to evaluate the relationship of cervical mucus monitoring (CMM) and the day-specific -pregnancy rate, in case of subfertility. A MEDLINE search revealed a total of 3331 articles. After excluding articles based on their relevance, 10 studies and were selected. The obs...

In this series we present the results of a retrospective analysis of 66 vasovasostomy procedures performed between 1983 and 1991. Obstructive intervals and serum antisperm antibodies were correlated with pregnancy and patency rates. With obstructive intervals of less than 5 years a patency rate of 100% (31/31) was obtained. Even more than 10 years after reversal, pregnancy occurred in 25% (2/8)...

BACKGROUND The addition of recombinant LH (rLH) to controlled ovarian hyperstimulation (COH) shows a beneficial effect on ongoing pregnancy rates in poor responder women, with an increase of ongoing pregnancy rate. Next to this possible beneficial effect, there are two potential drawbacks of adding rLH to COH; women have to administer extra injections, and daily rLH injections generate addition...

Unintended pregnancy rates typically include all women in the denominator. This understates adolescent rates because many adolescents are not sexually active. When rates are recalculated including only sexually active people, adolescents aged 15-19 years have the highest rates, arguing for a continued focus on adolescents in efforts to reduce unintended pregnancy.
