Various chemical, honnonal, vas based and herbal contraceptives have been examined and few of them have reached the stage of clinica1 testing. Promising leads have been obtained from testosterone bucic1atelundecanoate, alone or in combination with levonorgestrel butanoate or cyproterone acetate, RlSUG, an injectable intra vasal contraceptive and a few herba1 products, particularly the seed products of Carica papaya.

Testosterone is the most important naturally existing sex hormone for men and is used for its anabolic effects providing increased muscle mass. Testosterone is taken orally or by intramuscular injection in its ester form and are available illegally in different forms of esters. Anabolic androgenic steroids are today analyzed only in urine. To differentiate between the human natural testosterone and exogenous supply the quote natural testosterone and epitestosterone is used.

  • Male Contraception: Expanding Reproductive Choice
    Indian Journal of Experimental Biology Vol. 43. November 2005. pp. 1032-1041 Review Article Male contraception: Expanding reproductive choice M RajaJakshmi" Department of Reproductive Biology. All India Institute of Medical Sciences. New Delhi 110 029. India The development of steroid-based oral contraceptives had revolutionized the availability of contraceptive choice for women. In order to expand the contraceptive options for couples by developing an acceptable. safe and effective male contraceptive. scientists have been experimenting with various steroidal/non-steroidal regimens to suppress testicular sperm production. The non-availability of a long-acting androgen was a limiting factor in the development of a male contraceptive regimen since all currently tested anti-spermatogenic agents also concurrently decrease circulating testosterone levels. A combination regimen of long-acting progestogen and androgen would have advantage over an androgen-alone modality since the dose of androgen required would be much smaller in the combination regimen. thereby decreasing the adverse effects of high steroid load. The progestogen in the combination regimen would act as the primary anti-spermatogenic agent. Currently. a number of combination regimens using progestogen or GnRH analogues combined with androgen are undergoing trials. The side effects of long-term use of androgens and progestogens have also undergone evaluation in primate models and the results of these studies need to be kept in view. while considering steroidal regimens for contraceptive use in men. Efforts are also being made to popularize non-scalpel vasectomy and to develop condoms of greater acceptability. The development of contraceptive vaccines for men. using sperm surface epitopes not expressed in female reproductive tract as source.

However, the Petr Pavek, Charles University, enzymes involved in the hydrolysis of the esters have not been identified. There is one Czech Republic study indicating that PDE7B may be involved in the activation of testosterone enanthate.

ABSTRAK Tujuan: untuk mengetahui keamanan dan efektivitas dosis hormon testosteron undecanoate (TU) dan depot medroxyprogesterone acetate (DMPA) guna mengembangkan potensi kontrasepsi pria. Metode: dilakukan penekanan kadar sperma tikus melalui peningkatan apoptosis sel germinal secara in vivo melalui pemberian androgen kerja panjang yang merupakan kombinasi TU dan DMPA. Tikus jenis Sprague-Dawley dewasa diberi TU dengan dosis 2,5 mg setiap 6 minggu dan DMPA 1,25 mg setiap 12 minggu selama 60 minggu, yakni suatu regimen pengobatan yang diketahui dapat mempercepat penurunan produksi progesteron oleh testis dan menyebabkan azoospermia dalam waktu 12 minggu. Data tentang kadar sperma ditransformasi dalam bentuk log terlebih dahulu sebelum dianalisis. Hasil dinyatakan dalam bentuk nilai rerata±SEM. ANOVA yang diikuti oleh uji post hoc digunakan dalam penelitian ini untuk menentukan perbedaan lintas waktu dan fase. Uji T dilakukan untuk menentukan perbedaan antar dua kelompok. Hasil: ditemukan apoptosis dalam bentuk peningkatan sel-sel germinal (80%) yang mengalami apoptosis secara bermakna ketika tikus diberikan TU+DMPA. Sel-sel germinal yang mengalami apoptosis dapat ditemukan pada beberapa spermatogonia (20%), spermatosit (30%), dan spermatid (50%).

The primary nonclinical review was submitted to DARRTS on April 18, 2008. An amended nonclinical review was submitted to DARRTS on April 12, 2013 and it contains the nonclinical executive summary, a more extensive summary of the nonclinical program, and changes/corrections to the original nonclinical review. Nonclinical Conclusion/Recommendation The Applicant’s nonclinical program, supplied references, available literature and general knowledge of testosterone provide reasonable assurance of the safety of testosterone undecanoate (TU) in hypogonadal men from a nonclinical perspective. Recommended Labeling Current nonclinical recommendations for labeling are provided below. Recommended labeling in the original nonclinical review of April 18, 2008 should be ignored because the Sponsor has submitted revised labeling since the original submission.
