This study evaluated for the first time the effects of different doses of the anabolic steroid nandrolone decanoate (ND) on the expression of ovarian steroid receptors (AR, ER-α (ESR1) and ER-β (ESR2)) and related sex hormones after treatment and recovery periods in adult rats. The animals were injected subcutaneously with doses of ND (1.87, 3.75, 7.5 or 15 mg/kg b.w.) or mineral oil (control group) for 15 days, and the experimental groups were divided into three periods of evaluation: (a) ND treatment for 15 days, (b) ND treatment and recovery for a period of 30 days and (c) ND treatment and recovery for a period of 60 days. Estrous cycle was monitored daily. At the end of each period, rats were killed for collection of blood and ovaries. Persistent diestrus occurred in all rats during ND treatment and after 30-day recovery. The highest dose of ND was able to maintain all rats arrested at diestrus until 60-day recovery. The expression of steroid receptors varied in a dose- and period-dependent manner, having a more pronounced response with the dose of 15 mg ND/kg. ND treatment increased serum levels of testosterone, 17β-estradiol and dihydrotestosterone, especially at the highest doses of 7.5 and 15 mg ND/kg. No change was observed in the levels of follicle-stimulating hormone (FSH), whereas levels of the luteinizing hormone (LH) varied according to the dose and period. In conclusion, the ovarian sex steroid receptors and sex hormones were restored only at lower doses of ND and after a longer period of recovery.

This study aims to evaluate serum levels of the Dehydroepiandrosterone sulfate (DHEA-S) and its relationship with some sex hormones such as Follicle stimulating hormone (FSH), Luteinizing hormone (LH), prolactin and testosterone hormone and the infertility type in some infertile Iraqi men. Blood and seminal fluid samples from (60) idiopathic male infertile and (60) healthful individuals as a control group aged (18 to 60 year) were collected from private clinics. Serum hormones (DHEA-S, FSH, LH, prolactin and testosterone) were measurement using Enzyme Linked Immunosorbent Assay (ELISA). The levels of DHEA-S, FSH, LH and prolactin are significantly higher (P≤0.01) expect of the testosterone level was significantly decreased (P≤ 0.01) in the infertile men as compared with control group. High significant differences (P≤0.01) were recorded when comparing the hormonal levels (DHEA-S, FSH, LH, prolactin and testosterone) according to the age groups. There are significant differences (P≤ 0.01) in levels of (DHEA-S, FSH, LH, prolactin and testosterone) in the infertility period.  Smoker infertile men have high levels (P≤ 0.05) in the DHEA-S and LH while have low levels in the prolactin hormones compared with control. Patients with family history have shown significant differences (P≤0.05) in the levels of DHEA-S, FSH, LH and prolactin. In conclusion, this study revealed significantly increase in the DHEA-S levels in the infertile men and negative correlation between DHEA-S and FSH. Therefore, DHEA-S has important role in the diagnosis and follow up of the male infertility.
