Oxidative stress and mitochondrial dysfunction of granulosa cells in polycystic ovarian syndrome.

Polycystic ovarian syndrome (PCOS) is one of the leading causes of anovulatory infertility in women, affecting 5%-15% of women of reproductive age worldwide. The clinical manifestations of patients include ovulation disorders, amenorrhea, hirsutism, and obesity. Life-threatening diseases, such as endometrial cancer, type 2 diabetes, hyperlipidaemia, hypertension, and cardiovascular disease, can be distant complications of PCOS.

Stem Cell-Based Therapy for Asherman Syndrome: Promises and Challenges.

Asherman syndrome (AS) has an adverse effect on reproductive health and fertility by affecting endometrial regeneration. Stem cell-based therapies hold promise for future use in activating non-functional endometrium and reconstructing the endometrium in vivo. It has been postulated that various endometrial stem cells (EnSCs) are responsible for endometrial regeneration.

[on oligozoospermia and asthenospermia].

Objective: To observe the clinical effect of Yihechun Capsules (YHC) on oligozoospermia and asthenospermia.

Methods: A total of 181 male patients with infertility were randomly divided into a YHC+Levocarnitine (LC) group (n = 93, including 42 cases of oligozoospermia, 20 cases of asthenospermia and 31 cases of oligoasthenospermia) and an LC control group (n = 88, including 39 cases of oligozoospermia, 22 cases of asthenospermia and 27 cases of oligoasthenospermia), the former treated with YHC (［0.3 g per capsule］, once 4 capsules, bid, 30 minutes after meal) combined with LC oral liquid (2－3 g/d, tid, at mealtime) and the latter with LC oral liquid only (2－3 g/d, tid, at mealtime).

[Compound Amino Acid Capsules combined with clomiphene for severe oligospermia].

Objective: To study the effect of Compound Amino Acid Capsules (CAAC) combined with clomiphene in the treatment of severe oligospermia.

Methods: A total of 104 patients with severe oligospermia admitted to our Center of Reproductive Medicine from January to September 2018 were randomly assigned to a trial (n = 60) and a control group (n = 44), the former treated by oral administration of CAAC combined with clomiphene and the latter with clomiphene only, both for 12 weeks. Comparisons were made between the two groups of patients in the sperm concentration, and the percentages of progressively motile sperm (PMS) and total motile sperm (TMS) before and after 4, 8 and 12 weeks of medication as well as the pregnancy rate during the treatment.
