Rising number of infertile males in India provokes the need of evidence-based comprehensive formula addressing unattended causes of male infertility. There is an innovative product*, a combikit available in Indian market, containing 30 tablets of antioxidant, multivitamin, amino acid and mineral tablets, with documented evidence on ingredients in treatment of male infertility, and 25 tablets of clomiphene citrate which is a timetested drug in treatment of male infertility (in particular oligospermia and/or asthenospermia). In order to assess efficacy of the product in Indian infertile male patients, we undertook phase IV multicentric clinical study, at 18 centers across India in 100 patients.Very high couple pregnancy rate of 53% was reported. As first line treatment of male infertility (in particular oligospermia and/or asthenospermia), the use of this innovative product therefore holds a strong promise.

The performance of a refrigeration cycle driven by a liquid refrigerant injected compressor is investigated to examine its energy saving characteristics and performance improvement. Mathematical models of the compressor, the condenser and their combination in a complete cycle are used. The model shows an increase of the suction mass flow, an associated increase of the compression power and a small change of the overall efficiency due to the reduced temperatures of the refrigerant discharge and the compressor body. A condenser fed with refrigerant of lower superheat and greater mass flow shows an improvement in performance due to an increase in the two-phase region, though the improvement depends on the secondary fluid flow conditions. The thermal capacity and coefficient of performance of the total cycle increases with the injection ratio due to the combined effects of the compressor and the condenser.
