The ethanol extracts of leaves Alianthus altissima, Carrisa grandiflora, fruits of Citrullus colocynthis and aerial parts of Ruta graveolens was tested against fourth instar larvae of the mosquito, Culex pipines molestua Forskal through sublethal doses at the concentrations 5, 10, 15 and 20 ppm. The extracts of C. grandiflora, A. altissima and R. graveolens were prolonged IV-P time with 9.7, 10.3 and 12.8 days at 20 ppm. Whereas, the period shorted to 4.3 days for C. colocynthis in comparison with control 7.3 days. All the plant extracts extended pupal period with significant time, but not more 3.1 days, and 2.1 days for untreated pupae. The reproductive parameters as egg laying hatchability, fecunidity, fertility and sterility percent were showed significant values of emerged adults treated with the plant extracts at IV larval instar.

New approaches need to be pursued towards the assessment of sperm quality using biochemical markers and develop this markers to assess sperm function. The current study included analyzed 52 samples of human's seminal fluid wich classified into three classes: fertile normospermea (control), infertile oligospermea and azospermea. The percentage of dead sperms were obtaind by using eosin die in addition to the use of trypan blue to show the intact acrosome. The results of the study showed that the concentration of sperm in human's seminal fluid samples was (63x106/ml).The results showed ahigher level of creatine kinase CK  activity in human seminal plasma in an infertile oligospermic (113.3±17U/L) and azospermic cases (97.1±11U/L) in comparison to the control normospermic case (48.5±9U/L).

The present study aimed to investigate the effects of Phoenix dactylifera on reproductive system in male white albino rats Rattus norvegicus. 24 adult male albino rats were used, 18 were treated orally with Phoenix dactylifera at dose 100, 200, 300 mg/kg body weight for 6 weeks, 6 rats were treated with distal water served as control group. The results show that relative weights of epidydimous, seminal vesicles, prostate gland and rate of body weight, are significantly none changed. The result showed increased significantly in the weight of the testes for group treated at dose 200 mg/kg body weight.Increased sperm count and life sperm %, while decreased in dead sperm % and non change in the abnormal sperm %significantly. The result show increased in serum blood level of testosterone hormone in treated rat with Phoenix dactylifera at dose 300mg/lg body weight for 6 weeks, and there is no change in serum blood level of testosterone hormone in treated rats with Phoenix dactylifera at doses 100, 200 mg/kg body weight.

The present investigation was conducted to reveal the effect of oral administration of diazepam (2.5-5 mg/kg B.W.) orally daily for 6 weeks on sperm concentration, the level of live sperm, dead and abnormal sperm and the relative weight of testis, prostate, seminal vesicles and epidydimus (head, body, tail). Furthermore measurement of testosterone hormone level in time interval (0,3,6 weeks) in adult albino male rats with age between 2.5-3 months and average body weight (222±16.79gram). The results showed that diazepam at doses (2.5-5 mg/kg) body weight caused a significant decreas in sperms count and the percentage of live sperms with a significant increased in the percentage of dead sperms and morphologically abnormal sperms.
Furthermore a significant decreas in serum testosterone, average weight of testis, prostate glands and tail of epididymis associated with significant increased in average body weight during period 2,4,5,6, weeks in rats treated with diazepam at two doses 2.5,5 mg/kg of body weight compared with control group. It is concluded from the present study is that diazepam has adverse effect on sexual efficiency in adult male.
