Pregnancy prevention

There does not appear to be any clinically significant delay in return of fertility after discontinuation of progestogen-only contraceptives. Although there have been no large studies, data from several small studies suggest no effect. Furthermore, because progestogen-only contraceptives prevent ovulation in only about half of cycles, and because the pregnancy prevention effects fall rapidly if a tablet is taken late, the normal reproductive physiol-ogy presumably returns quickly after tablet discontinuation. 

In conclusion, contraception therapies with vaginal rings present excellent efficacy with little risk of side effects and appear to be as effective as oral contraception and IUD, in terms of pregnancy prevention [42]. Moreover, rings are characterized by important benefits like ease of use, long-term schedule, and user-controlled application. These versatile drug delivery systems appear to be safe, effective, and acceptable.

S.M.A.R.T. ) and the Accutane Pregnancy Prevention Protocol (PPP) to be used in conjunction with the prescription of Accutane. Management of toxic effects involves monitoring by the appropriate specialist and discontinuation of the exposure where indicated. Isotretinoin-related depression may require long-term monitoring. 

I pneumocytes and blood-air barriers often occur (Maritz et al., 1994). On the other hand, ascorbic acid supplementation during pregnancy prevents the inhibition of glycolysis in the neonatal lung (Maritz, 1987, 1993). This implies that ascorbic acid can prevent these cells from damage related to the inhibition of glycolysis. 

The history of the development of condoms precedes a review of the use of natural latex mbber condoms, with details of some of the problems encountered by users, and the subsequent development of a polyurethane condom by London International Group. The use of condoms for both pregnancy prevention and as a barrier to sexually transmitted diseases, including AIDS, is discussed, and the effectiveness of both latex and PU for this purpose. The use of polyurethane condoms as an alternative to latex by those experiencing latex sensitivity, either due to the protein in the rubber or vulcanising agents is proposed, since polyurethane has been shown to be non-allergenic. Test methods for condoms are examined, and results of in-use studies of the Avanti condom made from Duron brand PU are discussed. 3 refs.
