BACKGROUND The men's attitudes towards family planning and on the use of family planning method may affect not only their wives intention to use contraception but also the choice of a particular family planning method. This focus of this study is to assess the educated men's role, belief, practice and their participation in family planning. METHODS A cross-sectional data on 150 university mal...
INTRODUCTION Gender equality has been a priority area of demographic research. One of the major reasons for high fertility and low acceptance of family planning is the prevalence of gender preference among couples. The objectives of this study were to identify the determinants and examine the extent of gender preference on fertility. METHODS This is a cross-sectional study carried from June 2...
More than a quarter of couples worldwide depend on male contraception.1 Yet, vasectomy aside, male contraceptives are not very reliable. The unintended pregnancy rate with condoms, for example, is 15% to 20% a year.2 This unreliability probably helps explain why more than half of men might try a male hormonal contraceptive (MHC).3 Indeed, new male contraceptives seem to be popular across all ra...
METHODS — The only effective method available for male contraception is vasectomy, which divides the vas deferens in a minor surgical procedure [1]. The procedure takes about 15 minutes and can be performed in an appropriately equipped office or ambulatory surgery center [2]. No-scalpel vasectomy is the preferred vasectomy technique in the United States (US) because of its lower complication ra...
The recent discovery of nonsteroidal selective androgen receptor modulators (SARMs) provides a promising alternative for testosterone replacement therapies, including hormonal male contraception. The identification of an orally bioavailable SARM with the ability to mimic the central and peripheral androgenic and anabolic effects of testosterone would represent an important step toward the "male...
BACKGROUND This study was performed to assess spermatogenesis suppression and safety of a new combination of an etonogestrel (ENG) implant combined with testosterone undecanoate (TU) injections for male contraception. This is the first large placebo-controlled study for male hormonal contraception. DESIGN AND STUDY SUBJECTS In this double-blind, multicenter study, we randomly assigned 354 hea...
Urokinase-type plasminogen activator (uPA) is closely related to male reproduction. With the aim of investigating the possibility for uPA as a potential contraceptive target, in the present work, Kunming male mice were immunized by human uPA subcutaneous injection at three separate doses for 3 times. Then the potency of the anti-human uPA antibody in serum was analyzed, and mouse fertility was ...
The blood-testis barrier (BTB) is one of the tightest blood-tissue barriers in the mammalian body. It divides the seminiferous epithelium into the basal and the apical (adluminal) compartments. Meiosis I and II, spermiogenesis, and spermiation all take place in a specialized microenvironment behind the BTB in the apical compartment, but spermatogonial renewal and differentiation and cell cycle ...
Novel male contraceptives have been in development for almost as long female methods, yet there are no products available on the market. Hormonal approaches tested clinically to date include use of oral, injectable, implant and transdermal methods. The study attitudes toward contraception has inconsistent systematic reviews drawing these data together. We conducted a review evidence acceptabili...
Semen analysis as an integral part of infertility investigations has a surprisingly long history, emerging only slowly, from under a cloud of disrepute and occupying a solitary niche outside conventional pathology tests, until relatively recently. From origins in the 19th century when spermatozoa were only identified as present or absent in cervical mucus samples from postcoital tests, even the...
