Abstract:
<em>Spermicides are agents that immobilize or kill the spermatozoa in the vagina and exert their contraceptive effect. However, recent clinical trials have shown that detergent spermicides do not provide any protection against sexual transmitted diseases and auto immune disorders but may in fact even promote their transmission. Currently</em><em>, there were various types of contraceptives developed having dissimilar mechanism of action. These contraceptives are prepared from natural as well as synthetic sources. These contraceptives act by avoiding the fusion of sperm into ovum, alteration in

Abstract:
Sexually transmitted infections (STIs) and human immunodeficiency virus (HIV), the causative agents of acquired immunodeficiency syndrome (AIDS), are two great concerns in the reproductive health of women. Thus, the challenge is to find products with a double activity, on the one hand having antimicrobial/antiviral properties with a role in the reduction of STI, and on the other hand having spermicidal action to be used as a contraceptive. In the absence of an effective microbicide along with the disadvantages of the most commonly used spermicidal contraceptive worldwide, nonoxynol-9, new emph

ABSTRACT: In view of the need for improved vaginal formulations that are contraceptive, that may prevent transmission of sexually transmitted infections, or both, a new delivery system (base formulation; called Long Acting, Sustained Release of Spermicide, or LASRS) was developed that contains bioadhesive and other ingredients with a long history of safety, and was designed to provide long‐lasting vaginal retention of the formulation and to minimize possible vaginal irritation caused by incorporated active ingredients.

Anti-HIV activity was tested by measuring viral p24 antigen production as a marker of viral replication in HIV-1-infected human peripheral blood mononuclear cells.

Sperm motility was completely inhibited within 20 s at a minimum effective concentration (MEC) of 120 μg/ml.

Abstract:
The inhibitory effect of Old Coke, caffeine-free New Coke, New Coke, Diet Coke and Pepsi-Cola on human sperm motility was studied with a trans-membrane migration method. None of them could decrease sperm motility to less than 70% of control within one hour. A previous study which claimed a marked variation of spermicidal potencies among different formulations of Coca-Cola could not be confirmed. Even if cola has a spermicidal effect, its potency is relatively weak as compared with other well-known spermicidal agents.

The shape, size and number of sperm males produce and the characteristics of the reproductive tract through which they must travel have been shaped by a multitude of evolutionary forces. The selective pressures acting on sperm and the female tract have produced a wide variety of forms, some of which are unusual to the point that they appear maladaptive. This thesis uses a range of behavioural, physiological, morphometric and theoretical techniques to investigate the evolutionary causes and consequences of non-fertile sperm and spermicide in the Drosophila obscura species group.

It also includes those substances which alter the physiological functions of the body, examples of which would be contraceptive substances, such as the spermicidal compound nonoxynol-9, and the progestagen used as an oral contraceptive.

Chelation is one of chitosan's most useful characteristics. It can selectively bind to specific substances, including protein, tumour cells, metal ions, lipids, and cholesterol. Additionally, because it is biodegradable by nature, it does not result with allergic responses or rejection.

Community-based distribution (CBD) is the use of nonprofessional local distributors or agents to provide family planning (FP) methods—typically condoms, pills, and spermicides—and referral for other services. FP programs in Africa, Asia, and Latin America have implemented CBD programs for the past 30 years. There is a large body of evidence on the effectiveness, cost, and sustainability of CBD models. Most evidence supports using CBD where appropriate conditions exist. However, major changes have taken place in the context in which programs operate, including the onset of the HIV/AIDS pandemic
