Abstract Background Myrianthus arboreus P. Beauv. (Cecropiaceae) is a medicinal plant used to treat female infertility. The aqueous extract of M. arboreus leaves was found to improve the fertility of healthy female Wistar rats. In the present study, we proposed evaluating the effects of such an extract on an animal model of infertility caused by polycystic ovary syndrome (PCOS), in order to bring scientific evidence to the curative action of this plant against female infertility. Methods Following a 21-day administration (gavage) of letrozole (1 mg/kg), animals with PCOS, indicated by overweight and an estrous cycle blocked in the diestrus phase, were co-treated with letrozole (1 mg/kg) and the aqueous extract of M. arboreus leaves at doses of 20, 110 and 200 mg/kg. The positive control received clomiphene citrate (1 mg/kg) and metformin (200 mg/kg). The negative control received distilled water. Each group of animals was made up of 10 female rats. Vaginal smear was examined 7 days before and during co-treatments. Co-treatments were orally administered for 30 consecutive days and 5 animals per group were sacrificed thereafter for biochemical and histological analyses. The 5 remaining animals in each group were crossbred with males of proven fertility for 5 consecutive days. The daily examination of vaginal smears allowed evaluating fertility index. Following parturition, gestation rate was calculated. Results The aqueous extract of M. arboreus leaves reversed letrozole effects by decreasing body weight, abdominal fat accumulation, and serum levels of LH and testosterone (p < 0.001). Ovarian dynamic was improved and the number of tertiary, Graafian follicles (p < 0.001) and corpus luteum increased while that of cystic (p < 0.001) and atretic follicles (p < 0.01) decreased. These effects were associated with increased serum levels of estradiol, decreased ovarian oxidative stress, the resumption of the estrous cycle, the hypertrophy of uterine epithelial cells and increased fertility index and gestation rate. Conclusions These results justify at least in part, the traditional use of M. arboreus against female infertility and suggest that this plant could be a promising alternative treatment to improve symptoms associated with different PCOS phenotypes.

This study was designed to investigate the effect of penicillin on reproductive function in female Wistar rats. Fifteen female rats (120 – 160 g) were used for the estrous cycle and histopathological studies. Penicillin (17.14 mg/kg) was administered orally on daily basis for 21 and 50 days respectively for the estrous cycle and histological studies. Estrous cycle was carried out using the technique of Marcondes et al., histologies of the ovaries and uteri were also carried out. Data were analysed using descriptive statistics and student’s t-test at p=0.05. Treatment of rats for 21 days with penicillin (17.14 mg/kg) produced significant (p<0.05) increments in the estrous and metestrous phases as well as a significant (p<0.05) reduction in the proestrous phase of the estrous cycle relative to their respective controls. The histopathological study presented with a moderate endometrial congestion. It can therefore be concluded that penicillin probably has a pro-fertility effect with a moderate deleterious effect on the uteri at histological level in female Wistar rats.

The present study aimed to determine if gossypol interferes with ovarian follicles in rats. Twenty-four female Wistar rats were assigned to two equal groups: one control group and the other dosed with gossypol (25 mg/kg/day, subcutaneously) for 15 days. Ovarian follicles were histologically classified according to the stage of development and as normal or atretic. Gossypol treatment reduced the length of estrous with an increase in the duration of the diestrus phase. This compound was responsible for reduced serum levels of T4 and progesterone. Treatment with gossypol was responsible for a significant reduction in the number of normal ovarian follicles and a significant increase in the number of atretic follicles, both in all stages of development. Thus, treatment of rats with gossypol was responsible for reduction in the number of viable follicles and changes in hormone levels that resulted in interference of the estrous cycle.

This study was designed to investigate the effect of artesunate on reproductive function in female Wistar rats. Fifteen female rats (120 – 160 g) were used for the estrous cycle and histopathological studies. Artesunate (1.43 mg/kg) was administered orally on daily basis for 21 and 50 days respectively for the estrous cycle and histological studies. Estrous cycle was carried out using the technique of Marcondes et al., histologies of the ovaries and uteri were also carried out. Data were analysed using descriptive statistics and student’s t-test at p=0.05. Treatment of rats for 21 days with artesunate (1.43 mg/kg) produced significant (p<0.05) increments in the estrous and metestrous phases as well as a significant (p<0.05) reduction in the proestrous phase of the estrous cycle relative to their respective controls. The histopathological study presented with ovarian medullar that is severely congested (hemorrhagic) including expanded lumen of the endometrial glands. It can therefore be concluded that artesunate probably has pro-fertility effect with deleterious effect on the ovaries at histological level in female Wistar rats.

This study was designed to investigate the effect of methotrexate on reproductive function in female Wistar rats. Eighteen female rats (120 – 160 g) were used for the estrous cycle and histopathological studies. Methotrexate (0.071 mg/kg) was administered orally on daily basis for 21 and 50 days respectively for the estrous cycle and histological studies. Estrous cycle was carried out using the technique of Marcondes et al., histologies of the ovaries and uteri were also carried out. Data were analysed using descriptive statistics and student’s t-test at p=0.05. Treatment of rats for 21 days with methotrexate (0.071 mg/kg) produced significant (p<0.05) reductions in the proestrous and estrous phase of the estrous cycle as well as significant (p<0.05) increments in the metestrous and diestrous phases of the estrous cycle relative to their respective controls. The histopathological study revealed that treatment of rats with methotrexate (0.071 mg/kg) for 50 days presented with ovarian medullary part that is congested and oedematous as well as with multiple foci of hemorrhage within the endometria. It can therefore be concluded that that methotrexate probably has dominant pro-fertility effect, but also probably induced deleterious effects on the ovaries and uteri in female Wistar rats.

The biochemical and toxicological effects of aqueous extract of Parquetina nigrescens leaves (AEPNL) at the doses of 50, 100, and 200 mg/kg body weight on mifepristone-induced in Polycystic Ovarian Syndrome (PCOS) was investigated in female Wistar rats. Sixty female Wistar rats (190.00 ± 13.00 g) were assigned into 6 groups (A - F) of ten each: animals in group A received 0.5 ml of distilled water orally on daily basis for 30 days while the mifepristonized rats in groups B, C, D and E also received orally 0.5 ml of distilled water, 7.14mg/kg of metformin (reference drug) and same volume of the extract corresponding to 50, 100, and 200 mg/kg body weight of AEPNL respectively after which levels of some biochemical and toxicological indices were determined. AEPNL aggravated mifepristone-treatment related increases in albumin, total protein and liver aspartate aminotransferase activity and mitigated the increases in globulin, total bilirubin, urea, creatinine, liver and serum alkaline phosphatase and alanine aminotransferase activities, and no treatment-related histoarchitectural changes occurred in the liver, kidney and uterus of the female rats. Therefore, the aqueous extract of Parquetina nigrescens leaves attenuated and also aggravated some biochemical parameters in the serum, liver and kidney but with no histological changes in the liver, kidney and uterus of the mifepristonized female Wistar rats.

Aim: The increasing rate of infertility in humans has necessitated the need to assess commonly used medicinal plants to ascertain their effects on reproductive functions. The aim of this study was to determine the effects of tetrapleura tetraptera fruit extract on reproductive hormones and fertility in females. Methods: A total of seventy two (72) adult female wistar rats weighing 160-180 g were randomly assigned into four groups of 18 animals each. Group1 (control) was administered distilled water, groups II, III and lV were daily treated with the extract at doses of 75, 150 and 300 mg/kg body weight, respectively, orally for 28 days. Thereafter, 6 rats from each group were sacrificed during oestrous phase and serum used for analyses of reproductive hormones; while remaining 12 females from each group were each cohabited with males (2:1), sacrificed at gestational age16 and fertility parameters were determined. Results: The results show that in the test groups, there was significant (P < 0.05 ) reduction in the levels of FSH, LH and Estrogen, with a significant (P < 0.05 ) increase in progesterone, when compared with the control. Also, the number of pregnant female rats, number of foetuses, and fertility index significantly (P < 0.05 ) increased in the test animals, compared with the control. Conclusion: We concluded that Tetrapleura. tetraptera fruit extract impairs reproductive hormones and fertility parameters in female rats, and therefore should be consumed with caution.

The histopathological study presented with no visible lesions on the ovaries and uteri, but few endometrial glands have expanded lumen. It can therefore be concluded that chloramphenicol probably has pro-fertility as well as exhibits non-deleterious effects on the reproductive tissues of female Wistar rats.

Fifteen female rats (120 – 160 g) were used for the estrous cycle and histopathological studies. Clindamycin (8.57 mg/kg) was administered orally on daily basis for 21 and 50 days respectively for the estrous cycle and histological studies. Estrous cycle was carried out using the technique of Marcondes et al., histologies of the ovaries and uteri were also carried out. Data were analysed using descriptive statistics and student’s t-test at p=0.05.

The histopathological study presented with no deleterious effects on the ovarian and uterine tissues in the rats. It can therefore be concluded that clindamycin probably has pro-fertility effect without deleterious effects on the ovaries and uteri at histological level in female Wistar rats.

ABSTRACT The mechanisms involved in the prolongation of the oestrous cycle following LH administration were studied in 4-day cyclic female Wistar rats. In females injected with LH on the morning of dioestrus I there was an increase in ovarian venous blood progesterone as compared with non-injected animals. In both LH-treated females, and those injected with progesterone on the morning of dioestrus I, a slowing up in follicular growth was observed from the afternoon of dioestrus I. The size of follicles greater than 400 urn present in LH or progesterone injected animals on the third day of cycle was similar to the size reached by the same range of follicles in non-injected animals on the second day of the cycle. Hence, the increase in endogenous ovarian progesterone elicited by LH was considered as the cause of the slowing up of follicular growth and therefore of the lengthening of the oestrous cycle duration in female rats injected with LH at the beginning of 4-day cycle.
